Do-it-yourself supply valves for plastic windows

Ventilation is needed in almost any room, especially in those rooms where high humidity can lead to mold and destruction of the wall surface. Although a well-ventilated bathroom will not only increase the life of the finish and reduce the likelihood of mold growth, it will also improve air quality. After all, it is the lack of oxygen and excess carbon dioxide in enclosed spaces that make staying in them not so comfortable. A properly installed ventilation grille in the bathroom door will eliminate several problems at once.

The importance of ventilation in bathroom walls has been noted by builders for a long time. However, not every one of them also provided door ventilation in such a room. It was ensured by the presence of:

gaps between the canvas and the jamb;
structural irregularities;
porous structure of wood (the main material for door panels).

Thanks to modern technologies, it is possible to produce doors without defects. This means that you have to make holes in the canvas yourself or choose the already built-in ventilation in the bathroom doors. By installing a door leaf that does not provide fresh air flow, you can significantly worsen the conditions in the room. While taking a bath or performing other hygiene procedures, a person begins to feel uncomfortable. Small savings on ventilation can lead to serious problems.

Options for ventilation devices in bathroom doors

There are many options for ventilated bathroom doors. Their features depend primarily on the material of the door leaf:

Types of valves

There are 4 main types, differing in installation method and some functional features:

folded;
slotted;
invoices;
valve handle.

How to choose the right plastic windows

Folded

The most affordable and easiest to install option. The advantage of this type is that installation does not require removing and disassembling the window. To install, it is enough to make small cuts in the window narthex through which air from the street will pass.

The throughput capacity of such valves is small, ventilation can sometimes be insufficient, but the sound insulation is not reduced at all. The air flow is regulated manually using a special valve.

Slotted

Provide more efficient ventilation compared to rebated valves due to increased throughput. This type of valve also does not require dismantling the windows during installation.

The gap for air flow measures 1.2-1.6 cm in height, 17-40 cm in width. The device is protected from dust and insects by a special access block installed on the outside of the window.

Invoices

Valves of this type can only be installed simultaneously with the installation of plastic windows, since they require a special place on the frame. Installation into an existing double-glazed window is not possible.

Overhead ventilation valves are characterized by increased throughput and provide an excellent level of ventilation, but impair sound insulation and heat savings.

Handle valve

An original solution to the ventilation problem, which has a number of advantages:

The direct-flow device prevents freezing of the window profile and the formation of condensation when cold air enters
When combined with an exhaust system, the valve reduces humidity and maintains a comfortable microclimate in the room.
The device provides natural air flow, which makes use comfortable in the cold season.
Ventilation of this modification does not degrade the design of the windows.

In addition, a special air filter protects the room from dust. The filter requires regular replacement (every 6 months).

Types of ventilation grilles in bathroom doors

There are only two options for installing ventilation grilles. The first method is to install the grille in a rectangular hole cut to size. The second is the installation of small round through rings at the bottom of the door. Such grilles and meshes must match the color scheme of the main part of the door leaf. A large selection of suitable elements simplifies this selection. The grilles, almost merging with the structure, are invisible against the general background. They are made from the same material as the door itself or from painted plastic and metal.

A round vent in the bathroom door is an additional option that is most often chosen for installed structures. In addition, this method will be more profitable and will require the installation of several plastic rings rather than a rectangular grille. Sometimes they are left empty to improve ventilation. However, most often they are protected with a special mesh - to increase the sound-absorbing properties and improve the aesthetic characteristics of the door.

In addition to grilles and openings (or instead of them), simpler ventilation can be provided (see). It is a small (5-10 mm thick) gap under the bathroom door. Although the efficiency of this option is less than that of the others, the gap itself is rarely left by apartment owners for fear of flooding the property.

Making your own ventilation in the bathroom door

Despite the wide range of options for doors with ventilation grilles and openings, finding the right one for a specific apartment and environment is not easy. It will be much easier:

buy a suitable canvas, matching it to the design of the bathroom and, possibly, also the corridor;
select the ventilation grille option;
install ventilation yourself or contact specialists.

Cutting a hole and installing gratings (rings) is a relatively simple process, although special tools may be required. It is most difficult to carry out such work for glass doors; they should be entrusted to a professional. Plastic and wooden structures are much easier to drill and saw. The grille parts are installed into the cut hole on both sides, securing them using the method specified by the manufacturer. Some of the gratings are glued, the rest are mounted on self-tapping screws. For round hole rings, there is only one option - glue.

The resulting door as a result of such installation usually turns out to be no less effective for creating additional air exchange in the bathroom than the finished structure. At the same time, it looks more profitable thanks to the selection and installation of the grille after purchasing the canvas. And in terms of price, including labor and materials, it costs about the same as a door with already built-in ventilation.

The lack of fresh air in the house can cause residents to feel unwell, since carbon dioxide accumulates in a room that is unventilated for a long time, and a sufficient amount of oxygen is required for normal human well-being. In addition, household chemicals and finishing materials release toxins into the air, which, when accumulated, can also be harmful to health.

If we talk about ventilation in the bathroom, then the situation here is even more serious. In the absence of air movement in a humid environment, mold fungi form, the surface of walls, doors, and furniture accumulate moisture and become unusable.

The problem of bathroom ventilation has become especially relevant over the past few years due to the appearance on the market of new noise-, hydro- and heat-insulating materials. Finishing with such materials makes the bathroom more comfortable and beautiful, but many of them do not allow fresh air into the room. When installing a fan in the bathroom, effective ventilation of the room will only occur when the door is open, since a draft is needed for the fan to work well. According to the rules, there should be a small gap between the bottom of the door and the floor, but most people find this approach inconvenient and unaesthetic and install doors that close very tightly, leaving no gaps.

All these problems can be solved by a ventilation grill installed on the door. Today on sale you can find doors with a built-in grille or with special ventilation holes-rings. But if the door is already installed and there is a problem with air circulation, then you just need to purchase and install a grille.

The need to install ventilation in the door leading to the bathroom

Many people believe that the bathroom is the cleanest and safest in an apartment or house. But that's not true. During operation, a lot of moisture is formed in it. Over time, it, unable to find a way out, settles on the surrounding walls, ceiling, towels and causes the appearance of mold or mildew. To prevent this from happening, you need to properly install the ventilation system in the bathroom in advance.

Thanks to modern technologies, you can find different options for exhaust devices. They can be either complex, multi-component, or ordinary: ventilation grilles on a wooden door to the bathroom.

Installation of exhaust ventilation

When the bathroom has an area of 15 square meters or more, then in this case it is advisable to install exhaust ventilation. The main work in this system will be performed by a centrifugal fan. It is installed in the ventilation shaft. Installation does not require skills, and you can install it yourself without any problems after reading the instructions.

Exhaust system

Before starting installation work, you need to check the ventilation shaft for draft. The centrifugal fan is installed exclusively in a vertical position and is inserted deep into the hole. It is fixed to the wall using self-tapping screws. When the installation is complete, power is supplied to the exhaust system. To do this, you need to run a power cable and install a switch in a suitable place. It is recommended to connect the wires to the general network in a de-energized state.

Another condition for installing exhaust ventilation will be the installation of a glass door in the bathroom. On the one hand, it perfectly withstands temperature changes and is not affected by hot steam and humid air. On the other hand, due to its tightness, there is no natural escape of humid air through such a door, which can lead to its accumulation in the room. Therefore, in a bathroom with a glass door it is necessary to install exhaust ventilation.

Installation of an overhead fan

In small bathrooms, you can ensure the removal of humid air by installing an overhead fan. The main point here is the exact choice of the power of the device, otherwise there will be no use from it. To determine the power, you need to use expert calculations. For a family of three, the bathroom area must be multiplied by six. The resulting number is the required fan power. When more than three people live in an apartment, the area is multiplied by eight.

Overhead fan

Fan installation begins with mounting the box. Power is connected to it through a small cross-section cable using contact terminals. The next step is to fix the device box. For this, no auxiliary devices are required, since the base is equipped with special latches. When the installation work is completed, check the operation of the unit. Surface-mounted fans have different designs and will fit into the bathroom interior.

The fan can be installed either vertically or horizontally. It can be safely mounted on a suspended ceiling.

Creating Vents

Ventilation in the door installed in the bathroom is one of the elements of the ventilation system. It may take the form of a small hole through which moist air is removed from the room. In some apartments and houses, such holes are the only solution to the problem.

Ventilation holes in the door

Ventilation holes are often made at the bottom of the door leaf and are a through window in the form of a circle or oval. To decorate such windows, you can use special decor in the form of rings. Decoration elements can be made of various materials (metal, plastic, wood), depending on the type of door. Work on creating ventilation holes is carried out in the following order:

First, markings are made. A decorative ring is placed at the bottom of the door and outlined with a pencil. For high-quality ventilation in the bathroom, at least three holes must be installed in the door leaf;
the next step is to drill the holes. This is done using a drill with a crown;
Upon completion of drilling work, rough areas should be thoroughly sanded with sandpaper. When the surface is well cleaned, you can coat it with varnish. Thanks to it, the door will not deform and swell from exposure to moisture;
The final stage is the installation of decorative rings.

Decorative rings for ventilation holes come in a variety of variations. Nowadays, in addition to simple and aesthetic rings, you can find mesh components coated with soundproofing or soundproofing material.

A variety of decorative rings

Round holes in the door are not the only solution to the issue of providing ventilation in the bathroom. In everyday use you can find unique gratings. Unlike rings, this system has angled louvres that prevent drafts from getting through.

Ventilation grille at the bottom of the door

The grille is an order of magnitude larger than the ventilation rings. On the one hand, this provides better ventilation in the bathroom, and on the other hand, it is very noticeable. To smooth out this drawback, you should choose a grille exclusively to match the color of the door leaf.

Installation of the ventilation grille is carried out in the same way as the holes. Only it should be located exclusively in a vertical position.——-

Bathroom door material

Due to the huge selection of materials for the manufacture of interior doors, we can highlight those that are especially suitable for bathrooms.

Doors made of natural wood. One of the most suitable options, since the ventilation of the room in this case is much better. To prevent the door leaf from being damaged by moist air and steam, it is necessary to treat the surface with several layers of varnish.

Glass sheets perfectly tolerate hot steam and moisture, but hermetically seal the room. In this case, there is no point in talking about natural ventilation. It is necessary to install forced.

Plastic doors, like glass ones, are not afraid of moisture and retain internal heat well. In the price category, they are cheaper than their predecessors, but do not have an aesthetic appearance.

Budget doors made from chipboard and MDF are perfect for any interior design. Since their surface is coated with special solutions, they can easily withstand exposure to humid air.

Providing ventilation is a necessary requirement to create a normal environment in the bathroom. Absolutely anyone can build the necessary device. The above options are perfect for living rooms. Provided that all installation work was carried out in compliance with all norms and regulations, the removal of moist air will be carried out efficiently and uninterruptedly. Therefore, if you are not particularly confident in your abilities, then it is necessary to attract specialists to carry out such work.

Types of ventilation grilles

Today on the construction products market you can find many different variations of ventilation grilles. All these designs have differences in shape, purpose, design and color materials, sizes, and prices.

The primary classification feature that determines the types of gratings is the method and location of their installation. On this basis they are divided into:

inlet;
internal;
external.

Supply grilles are used for installation on doors. They are made from the following materials:

aluminum;
plastic;
tree;
steel and others.

Ventilation grilles made of plastic have high corrosion resistance and an affordable price. But when exposed to direct sunlight, the plastic loses its attractive appearance and may begin to deteriorate over time. Therefore, plastic grilles are best used for interior doors located inside the house.

Aluminum gratings are quite durable, light in weight, and not afraid of sunlight, but they are somewhat more expensive than plastic ones.

Wooden grilles are designed for indoor installation. Their advantages: environmental safety, external presentability, allowing them to fit harmoniously into the interior of the room. However, it should be borne in mind that natural wood requires special regular care, in the absence of which the product may lose its appearance and deteriorate. The cost of wooden ventilation grilles is high compared to other analogues.

Steel gratings are heavy and expensive, but at the same time they are considered the most durable and durable. Such structures are most often installed on entrance doors, since they are too heavy for interior doors.

When installing a grille on the front door, you must choose a model with a protective mosquito net to prevent mosquitoes and flies from entering the house.

Ventilation grilles allow very little light to pass through and virtually eliminate the possibility of visibility; through such a structure it is impossible to see the person behind the door. These products can be round, square or rectangular in shape, but the latter option is the most common.

Rectangular door grilles

Rectangular grilles are installed on kitchen doors, bathrooms and toilets. This allows air flow to circulate properly inside the rooms. In addition, such products are also used for mounting in window sills so that the warm air masses emanating from heating radiators are evenly distributed throughout the room.

These structures are made of high quality and durable plastic. Some models are equipped with insect screens or a movable damper that controls air flow. Also, if desired, you can install a grille with a built-in fan - in this case, the ventilation effect will be the best. Today there are various color and design options on sale, so for each door you can choose a grille that matches the color and style.

Round grates

The design of round gratings is practically no different from rectangular ones. Such products are also equipped with a mosquito net and may have movable dampers or a built-in fan. The size of round structures, as a rule, does not exceed 15-20 cm in diameter, and for their installation, round holes are made in the door according to the size. Products up to 10 cm in diameter are installed several pieces in a row along the bottom of the door. Larger bars can be placed on the sides of the bottom or top of the door. If there is moisture and mold inside furniture cabinets, such grilles are installed on the cabinet doors. In this case, glue and mounting ribs are used for installation.

Installation

If there is no proper air circulation in the office production room, as well as in the private bathroom, kitchen or toilet, ventilation grilles must be installed on the doors. You can do this yourself or seek help from specialists who will perform the following steps:

Building codes will determine the optimal grille size required for your door. The size depends on the internal dimensions of the room and its purpose.
They will make a hole of the required size in the door and install a grill.

For self-installation you will need the following tools:

Ruler and pencil;
jigsaw;
screwdriver or glue.

Work order:

First, using a ruler, you need to measure the dimensions of the purchased grilles (as a rule, there are always two of them in the set).
Next, you need to mark the places on the door where the grilles will be located. In this case, the holes should be approximately 1-2 mm larger than the length and width.
Then four round holes are made in the corners of the marking with a large drill.
Inserting the jigsaw blade into one of the holes, carefully cut out a rectangle of the appropriate size according to the markings. You need to cut carefully so that the material does not break off. Most indoor doors are filled with paper honeycomb inside. Please note that the jigsaw is suitable for doors made of wood or wood processing materials. For other materials, appropriate tools are used.
Now attach the gratings to both sides of the hole. If they fit too tightly, then enlarge the hole by sharpening it with a file or rasp.
If the product's operating instructions indicate that the grilles are attached with glue, then they will be attached using construction adhesive. Before applying glue to the surface of the door, it must be treated with a cleaning agent to remove dirt and grease. Otherwise, the grille may come off after some time. Most models designed for doors are fixed with self-tapping screws.

Fresh indoor air is the key not only to human health, but also to the safety of many finishing materials. In most rooms, the problem of oxygen flow is solved simply by ventilation. The bathroom has no windows, so it requires both forced and natural.

To create the first, fans are used, and with the second, doors with ventilation can help. Wooden and metal door ventilation grilles, which can be easily installed with your own hands, will help improve an already installed solid door. There are several options for door ventilation - which one is better to choose?

There are the following material options for making bathroom doors:

Glass
. Frosted glass doors are great for wet rooms - they are resistant to moisture and high temperatures, and they look good. They also easily withstand a large number of heating and cooling cycles, which is quite typical for a bathroom that is constantly filled with hot steam. If ventilation holes are not made in such a door in advance, it will not allow air to pass through.
Plastic
. The cheapest option, inferior to analogues in aesthetic characteristics. It withstands all aggressive influences just as well as glass. If you have certain skills, you can equip such a door with a ventilation grill.
Solid wood
. It is less resistant to moisture and temperature changes, but is best suited for organizing door ventilation.
Woodworking products
- laminate, chipboard, MDF - after treatment with special impregnations, withstand moisture well, and it is easiest to install ventilation in them. Like plastic models, this option is very cheap.

Thus, despite the worse resistance to moisture, wood options are better suited for organizing a constant flow of air - then you can even cut the ventilation grilles for the bathroom door with your own hands.

Methods of organizing ventilation

According to the standards for the bathroom, natural ventilation is provided - for this there must be a gap near the floor. However, in practice, this gap is usually closed with thresholds or a seal to avoid leaks during a flood. That's why bathroom doors with built-in ventilation have become widespread. There are two options for organizing it. You can also use a silent fan with a check valve - read more about the benefits

Ventilation grates

This option is a window cut out at the bottom of the door, covered with a plastic, wooden or metal grill.

Ventilation rings and grilles in doors

It is done from below because cool fresh air sinks to the floor due to convection.

Such gratings have a number of advantages:

variety of designs;
opacity;
the curtains create an obstacle to the continuous flow of air - there will be no draft in the room
, but oxygen will still continuously flow into the bathroom.

Grilles can have a variety of sizes and be installed in different quantities: one, across the entire width of the door, or several in a row - it all depends on the designer’s imagination.

Ventilation grille in the door

When installing it yourself, it is important to take into account this point: the overhead ventilation grill must be level, at right angles to the floor.

Ventilation rings

The location of such ventilation holes is similar to grilles - they are located at the bottom of the door, at a short distance from the floor. Essentially, these are simple holes in the door

, inside which plastic or metal rings are inserted, performing two functions:

improve aesthetics;
protect the cut from moisture and temperature.

The design of such devices is simple and less varied than that of gratings, but there are options here too.

Door manufacturing materials

Before installing the first door you come across in the bathroom, you need to understand whether it is suitable for organizing ventilation - whether it allows air to pass through on its own, and, if not, whether a grille or ventilation rings can be installed. Find out also about the optimal door sizes for a bathroom.

How to choose ventilation for a bathroom door

The easiest way is to choose a door that is factory equipped with vents. There is also a problem with this option: it can be difficult to find a model that fits the existing interior. But you don’t have to think about the material and choose any door you like.

The second way is to make holes with your own hands. In this case, you will have to look towards wooden models, since cutting glass at home is difficult, and besides, this requires a special tool.

Round ventilation holes in the door

Cutting plastic is simply dangerous - it is very easy to ruin such a door without the skills and experience of such work.

There is also a third option. If you can’t find a ready-made door with ventilation for the bathroom, and you don’t have the time or desire to tinker with the work yourself, you can use the simplest way to organize the flow of fresh air. Namely, cut off the door from below, making a gap between it and the floor. With due care, this will not spoil its aesthetics in any way, and the ventilation will be no worse than if there were special holes in the array.

DIY ventilation

Having decided on the option for organizing ventilation, you can get to work - making holes in wood or plastic will not take much time and effort, and you will only need the most basic tools for this.

You will need the following equipment and materials:

Ruler and pencil;
level;
drill, jigsaw or glass cutter;
grille or ventilation rings for the door;
mounting glue or self-tapping screws, depending on the ventilation model.

Installation is carried out in the following order:

The grid or rings are measured if the dimensions are not indicated in the documentation for them.
Markings are applied to the door leaf. Of course, you can simply attach a grid or ring and trace with a pencil, but accuracy in this case may suffer. Please note that a couple of millimeters on each side should be added to the ventilation size.
Using an appropriate tool, holes are drilled or sawed in the canvas.
The sections are carefully sanded with sandpaper and then varnished. This will further protect the material and improve the appearance of the door.
The rings are lubricated with glue and inserted into the holes; the grilles are screwed on with self-tapping screws on both sides. It is worth checking the evenness of the installation using a water level.

When working, be sure to follow safety precautions - use gloves and safety glasses.

If you are not sure that you can do everything correctly, it is better to entrust the work to a professional.

Thus, ventilation in the bathroom door is not a whim, but a necessity. Without it, the comfort of using the bathroom will be incomplete and even more - it will be simply dangerous. There is no point in avoiding organizing a constant flow of fresh air into this room - choosing the appropriate option is very simple, and installing the grille or rings with your own hands takes no more than half an hour, even for a person without experience.

How to choose a door with ventilation for the bathroom?

Finding a ventilated bathroom door in a store that will suit both your doorway and the style of your premises in all respects is quite difficult. This is why most homeowners prefer to make bathroom door vents themselves. Doing this yourself is not so difficult if we are talking about doors made of wood or wood-processed materials. Of course, cutting a hole for ventilation in glass or plastic doors yourself is quite difficult - in the first case you will need special equipment, in the second - dexterity and no fear of ruining the door, since plastic is a very unpredictable material.

If you decide to make a hole for ventilation in the bathroom door with your own hands, then you have two options:

An easy way
is to trim the bottom of the door a few centimeters. This method is relatively simple, but quite effective. In addition, it will not cause significant damage to the aesthetics of your door.
A difficult method
is to install a ventilation grille in the door space. To do this, you will need to purchase ventilation grilles (usually they are sold in pairs), measure them, apply markings to the door, adding a couple of millimeters to all four sides of the product. Depending on the door material, select a tool to cut a hole in the door leaf and carry out the procedure. After this, you need to install the bars on both sides of the door and fix them.

This way you can quickly and easily transform your bathroom into a space accessible to fresh air.

Ventilation is one of the ways to maintain an optimal internal microclimate. There are many devices that can improve air movement. All use ventilation grilles installed as guides.

DIY ventilation

You will need the following equipment and materials:

Ruler and pencil;
level;
drill, jigsaw or glass cutter;
grille or ventilation rings for the door;
mounting glue or self-tapping screws, depending on the ventilation model.

Installation is carried out in the following order:

The grid or rings are measured if the dimensions are not indicated in the documentation for them.
Markings are applied to the door leaf. Of course, you can simply attach a grid or ring and trace with a pencil, but accuracy in this case may suffer. Please note that a couple of millimeters on each side should be added to the ventilation size.
Using an appropriate tool, holes are drilled or sawed in the canvas.
The sections are carefully sanded with sandpaper and then varnished. This will further protect the material and improve the appearance of the door.
The rings are lubricated with glue and inserted into the holes; the grilles are screwed on with self-tapping screws on both sides. It is worth checking the evenness of the installation using a water level.

When working, be sure to follow safety precautions - use gloves and safety glasses.

If you are not sure that you can do everything correctly, it is better to entrust the work to a professional.

To ensure the movement of air from one room to another, you can use transfer grilles. This is a simple and cheap alternative for those who do not have a gap under the door: in this case, normal ventilation of the room may be disrupted.

Why exactly a grille is needed, what it can be like and how it is installed - we’ll look into it below.

Possible installation options

Forced ventilation in a window can be implemented in three ways, which vary greatly in complexity.

The most difficult method is adjusting the size of the opening

The most labor-intensive and costly method involves installing the above-mentioned overhead elements. They are mounted as follows:

The existing glass unit is removed.
The opening is expanded by the amount of the lining.
The glass unit is installed back.
An overlay is installed into the resulting gap.
The cracks are covered with cement mortar (or something similar).

The technique looks deadly labor-intensive and unreasonable. Therefore, no one does the work in this order, because it is fraught with cosmic expenditures of effort, time and money. It is necessary to take care of additional ventilation in advance, that is, before installing the double-glazed window.

Related article: Round windows with opening

The most thoughtful people, when ordering PVC windows, immediately plan to install additional air flow. To do this, the opening is made a little wider than the glass unit requires. This technique is the most effective, and most importantly rational.

Installation instructions for Aereco models

However, what to do if the double-glazed window is already in place? Models from Aereco are installed using a simpler method. It consists of the following:

A location for installing the channel is selected. If possible, this should be the least visible area.

Please note: additional window fittings should not interfere with installation. Take this fact into account when choosing a location.

Then marking is done.
We screw the bar to the selected location using special self-tapping screws for PVC structures.
We mark the location of the technological grooves on the vestibule.
We remove the bar. Using a drill and an electric jigsaw, we cut holes in the sash and the frame itself.
Setting the bar again.
We secure the valve using special latches.

This procedure is relatively labor-intensive. In addition, it requires special tools, which almost everyone has. Another factor is that a person without proper experience will not be able to do the job accurately. Conclusion - it is better to entrust the installation of such a device to a specialist.

Air-box - installation without problems

There is another technique that anyone can handle. The air-box manufacturer has created a model that can be installed without the use of tools. The kit includes a special seal and PVC screws. The work is carried out in the following sequence:

Select the intended installation location.
We cut off the standard seal in this place (which is located on the sash).
Insert a new one (from the kit).
Remove the protective film from the valve.
We secure it in the place where the new seal is installed using special latches.
Close the flaps and make a mark on the frame along the length of the valve.
We cut off the existing seal in this place and install a new one in its place (the same one from the kit).

If something is unclear to you, you can watch a video from the manufacturer himself. It will allow you to clearly understand everything.

Purpose

Transfer grilles are mounted in a hole made in the interior doors (less often in balconies or partitions). Their purpose is to ensure the movement of air between rooms: to remove “waste” and make room for fresh air.

Door manufacturers often produce products that do not provide a gap at the bottom (between the leaf and the floor). This gap is necessary precisely for ventilation: air passes through it even when the door is tightly closed. If this gap is absent (or exists, but there is also a threshold that blocks it), then the air is “locked” in the room, and you will have to open the door to ventilate.

Thus, the door grill allows for normal ventilation in the room when the door is closed and does not have an undercut (slot). Air entering the room through a window (or through a supply valve or installation) will be able to exit into the corridor and be removed through a ventilation shaft or hood.

To summarize: it is important to use sharpening machines in the following rooms:

bathroom (bathroom, toilet) - they are usually kept closed, and if the humid air stagnates, mold will form inside;
kitchen - “exhaust” air is removed through the kitchen hood, giving way to fresh air, and therefore it is necessary to provide the air flow with an unobstructed path to the hood;
in any room in which there is no gap under the interior door.

The use of such grilles is relevant not only in residential premises, but also in any other premises - offices, classrooms, classrooms, regardless of their purpose.

Device and material

Structurally, the product consists of two frames: external and internal. Internal frame - inserted directly into the door leaf (into the hole in it) on one side. There are lamellas on it.

For transfer models they have the shape of a corner, V-shaped. This allows air to pass through without problems, but completely blocks the view.

The outer frame is essentially decorative. It is attached to the other side of the door leaf, covering the edges of the sawn hole.

Another version of the design is less common: when the product simply consists of two gratings, each of which has its own slats. They are attached on both sides of the door leaf, opposite each other. This option is especially relevant if the thickness of the canvas is greater than the common 3.5-4 cm.

The material of the grilles is most often plastic: it is both cheap and practical (does not rust, is not afraid of moisture, and is easy to clean). Less commonly, door grilles are made from:

wood: such products are practically impossible to find in stores; they are usually made to order (they cost even more and require careful care; it is better not to use them for bathrooms).

To protect metal grilles from moisture, powder paint is applied to them. This allows you to install them in bathroom doors, but if the paint coating is damaged, the product will have to be either tinted or replaced.

Some models are equipped with a silencer (example -). This is a useful thing if you need to muffle the sound (passing into the room or from the room, it doesn’t matter).

Shape and dimensions

The shape of door grilles is most often rectangular. Less often it is a square or a circle.

The main characteristic is the size

. Most often the door leaf has the following dimensions:

70 or 80 cm - for interior doors;
60 cm - for doors to the bathroom, utility rooms;
thickness - 35-40 cm.

Based on this, manufacturers make transfer grids with a smaller width (no more than 60 cm). They can be installed in doors with a thickness of 25 to 50 mm.

The size range is approximately this:

width - from 100 to 600 mm;
height - from 100 to 250 mm.

Larger grilles are usually not found in stores; if necessary, they will have to be ordered.

From minimum to maximum, dimensions increase in increments of 50 mm (that is, 100x100, 150x100, 200x100, 200x150, 300x200, 500x250, and so on). For some manufacturers, the pitch may be 25 mm (not common).

The most common options are:

350x150;
400x150;

500 x200.

How much air will pass through: about the cross-sectional area

Another characteristic of gratings is the cross-sectional area. This determines how much maximum air can pass through the regrinding.

For comparison: the area of the door gap is approximately 120 cm² (for a leaf 80 cm wide, with a gap height of 15 mm). With normally operating exhaust ventilation, creating a normal pressure drop of 10 Pa, about 100-110 “cubes” of air will pass through such a gap per hour. This is more than enough to remove all the “exhaust” air from the room with the door tightly closed (about 30 “cubes” are needed for 1 adult per hour).

Please note: for ventilation grilles you need to pay attention to the open cross-sectional area

(in the specifications it is indicated as F l.s.), that is, the “clean” area of air passage. This figure is always about 30-40% less than the total grating area - due to the lamellas.

Ideally, the living cross-sectional area of a door grille (or several grilles in total that stand in one door leaf) should be more than 30-40 cm². Grates with dimensions of approximately 300x250, or 350x200 have this area. This will be enough to ensure normal air flow from the room in which 1 person is located.

Here is an approximate table of areas (total - Fо, and free cross-section - F l.s.) for gratings of various sizes:

If the room is not always kept closed, then it is not necessary to pay special attention to calculating the cross-sectional area. “Exhaust” air will be removed from the room when the doors are opened.

Also keep in mind that no more air will escape through the grill than enters. For example, if fresh air enters the room through a supply valve, which lets through an average of 35 “cubes” per hour, installing grilles that are too large is simply useless.

Manufacturers and prices

Here is a list of manufacturers of transfer grids whose products can be found on the markets of the CIS countries:

There are also products from other manufacturers. The average cost of door grilles is approximately the same as in the price table for Arktos AP.

How to choose a ventilation valve

The optimal ventilation device option should be selected individually for each room, based on its characteristics and operating requirements. Important parameters when choosing:

Installation requirements: the choice depends on whether the valve needs to be installed in existing plastic windows, or whether a new double-glazed window with ventilation will be installed.
The desired control option is manual, mixed or fully automatic.
Climatic conditions. It is important to understand at what temperature conditions the valve will have to operate, so that it does not violate the requirements for thermal insulation, does not become overgrown with ice, and effectively performs its functions.
Intensity of air exchange - the design must provide sufficient air flow from the street. The standard is approximately 30 cubic meters per hour per person.
Degree of sound insulation.

7 ways to make a plastic window not sweat

Today there is a large selection of ventilation valves, allowing you to purchase the best option for each case.

For example, a line for windows called Air-Box from the Russian manufacturer - Mabitek.

The assortment is represented by three main classes:

Standard is the simplest option. It includes two main elements - an external air intake located at the bottom and an upper conductor into the room. The valve petals open when the exhaust ventilation is running due to the rarefaction of the air. This ventilation provides an air flow of about 6 cubic meters per hour.
Comfort - mounted in a rubber seal or in a window profile of your choice (with or without milling the window profile). The AirBox Comfort ventilation valve has good noise insulation properties.
Comfort S is a special development for non-opening window profiles. During installation, through drilling is required for straight-through operation.

Ventilation in this line is characterized by an optimal combination of efficiency, low cost, compact dimensions and ease of installation. All this allows it to lead the market for similar products.

Effective operation of flow-type valves is possible only if exhaust ventilation is fully functioning.

Another popular ventilation group was developed by the French company Aereco . Installation is possible either on the wall of the room or in the slot of the window block.

Air exchange in devices from this manufacturer is controlled automatically using a special sensor. The size of the ventilation hole depends on the humidity in the room - the higher it is, the wider the valve opens.

The category is represented by several models, differing in noise insulation and throughput, for example:

EMM is a popular model, available in three colors - white, oak and teak. The air exchange of the valve is from 5 to 35 cubic meters per hour, regulation is carried out by a humidity sensor.
ENA2 - characterized by increased throughput - from 5 to 50 cubic meters per hour and increased sound insulation - 42 dB.

How to get rid of mold on walls

French vent valves belong to a higher price category, but do not require manual adjustment.

Ventilation holes in doors

To ventilate the apartment, special openings are provided in the doors, which are often decorated with grilles. Sometimes air circulation occurs through a small gap that remains between the door and the floor.

Ventilation holes in doors must be located according to certain rules:

They must be in dry rooms - bedroom, living room, office.
Exhaust holes are made in rooms with high levels of humidity - in the toilet, bathroom and kitchen.

Proper ventilation will ensure a constant flow of fresh air.

And so that there are no obstacles in its path, additional ventilation holes are made in the interior doors.

Main advantages and reviews of fresh air valves

As practice shows, more and more people are now inclined to purchase this useful device. It is not only healthy, but also very convenient. The main advantages of this device:

Ensuring an influx of fresh air from the street in a volume of up to 35 m3 per hour;
Reducing indoor carbon dioxide levels;
Providing a healthy and pleasant microclimate;
Elimination and prevention of such an unpleasant phenomenon as condensation on glass;
Complete elimination of the formation of fungus and mold on windows;
Air enters the room from above the window, so the movement of its masses is practically imperceptible;
Reduced heating costs;
Ventilation improves well-being and prevents oxygen starvation;
Installation takes place on an existing double-glazed window without first dismantling it.

Positive reviews from many consumers indicate that this is a very profitable purchase, which significantly improves the microclimate in the apartment.

Ensuring high-quality air exchange in a living space is essential for the health of all its inhabitants. This allows you to reduce the percentage of accumulation of microorganisms, toxins and radon gas, which have an extremely negative impact on human health.

Bathroom door with ventilation

There must be ventilation holes in the rooms, because in this room the air humidity is always high. There are several options:

Ventilation rings
- they cover the through holes drilled at the bottom of the door, they look neat and beautiful. Wood, metal, and plastic are used to make them. The simplest rings form ventilation holes and nothing else. But you can buy rings with a protective mesh or noise-absorbing properties. The latter are often installed in the bedroom.
Ventilation grilles
are mounted at the bottom of the door and can have an interesting design. Their main advantage is that the air does not flow through them directly, which means that there will be no drafts in your apartment.
Undercutting the door
is done in such a way that a small gap remains when closing. The cut area is covered with a special end edging.

If you are completely satisfied with the bathroom door, you can supplement it with ventilation ducts, which are sold separately. In all other cases, it is better to buy a bathroom door with ventilation.

How to ventilate a bathroom using a fan

Scheme for installing ventilation in the bathroom door.

If creating a gap under the bathtub does not help, then you can install a fan. Calculating the required power of the device is quite simple. To do this, the volume of the room is multiplied by 6 (if the number of people living in the house is no more than 3) or by 8 (if more than 3 people use the bathroom).

For example: if the bathroom area is 7 m², then the fan output should be 110 m³ per hour (if up to 3 people live) or 150 m³ per hour (if there are more than 3 people in the family). It is not recommended to install a fan that is too powerful; this can lead to rapid cooling of the air, increased noise levels and unwanted drafts.

You can mount the fan on the wall. The basic rule is that the fan should be located next to the ventilation hole. The store offers many models of fans that can be used for bathrooms. They should be hung out of reach of small children and animals. Its flat appearance does not spoil the appearance of the bathroom.

Diagram of the ventilation system.

For rooms larger than 15 m², it is better to hang a duct fan (installed inside the duct). When choosing it, it is better not to settle on overly powerful models, as it can redirect the air exchange of the entire apartment building. A powerful duct fan makes a lot of noise. It can only be installed in a private home.

For all fans, it is better to lay the wiring in the wall in advance (before laying the tiles) and connect it to a separate switch. Some people connect the fan to the light switch, so it turns on at the same time as the bathroom light. At the exit, when the light is turned off, the fan goes silent. If the noise of the fan is annoying, then it is better to turn it on after visiting the bathroom (by making a separate switch in advance).

Interior doors with ventilation grille

Doors equipped with a ventilation grill are a ready-made and convenient solution that is used in rooms such as:

Bathrooms;
Toilets;
Showers;
Locker rooms;
Industrial premises;
Laboratories.

Ventilation grilles with horizontal louvers are designed for free air circulation between rooms. They can have any shape, size and color, and be located at different heights.

The presence of a ventilation grille on the interior door prevents the formation of condensation and ensures long-term operation of paint and varnish and other coatings.

Pros of ventilation valves

Installing ventilation valves on plastic windows solves many problems and makes life noticeably more comfortable. Obvious advantages of their use:

Normalization of the microclimate of the apartment. A stable supply of air from outside reduces humidity, which prevents the formation of condensation and mold.
Ventilation occurs without dust and insects from the street entering the rooms. In addition, the noise level does not increase and dangerous drafts do not occur. There is no danger of children and pets falling out of the windows, as well as strangers entering from the street.
Fresh air is supplied around the clock, making it comfortable to stay in the room and easy to breathe.
If desired, you can manually adjust the ventilation intensity or completely close the ventilation valves.
In winter, the outside air heats up slightly as it passes through the device, which allows you to save heat with a sufficient supply of oxygen.
Easy to install and operate.

Air vents are a simple and inexpensive way to improve your quality of life.
