Holes in the bathroom door for fresh ventilation. Effective ventilation in the bathroom is the key to the health and well-being of the whole family. How to make ventilation on bathroom doors

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.

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:

frosted glass. It will not be possible to install a grille in such a door yourself, and there are practically no ready-made options. The only way to provide ventilation here is by drilling a hole;
plastic. The most cost-effective option, in which it is enough to simply install gratings (even on your own and without special skills);
tree. This material is less resistant to high humidity, but is still excellent for creating door ventilation. Thanks to the good workability of wood, it is relatively easy to embed a grille into such a door.

A bathroom door made of chipboard or MDF with a ventilation grill on its surface is one of the most profitable options (which bathroom door is best to choose, see). Its cost is lower compared to wooden and glass structures. Moreover, the aesthetic characteristics of this material are better than those of plastic.

Before cutting a hole for ventilation for bathroom doors, you need to apply markings to its surface in accordance with the dimensions of the grille. In this case, you need to add 1–2 mm to the length and width of the installed structure.

One of the most popular options is the combined door (see). That is, a structure made from two materials at once. For example, made of plastic and glass or wood and glass inserts. Ventilation is arranged in the wooden or plastic part of the door.

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.

Undercut in the bathroom door

Well, and the most inconspicuous option: undercutting the doors. The bottom of the bathroom door is trimmed a little so that even when closed there remains a small gap. And the cut site is covered with a special end edging.

If you are satisfied with your bathroom doors, you can simply retrofit them with ventilation ducts: these products are sold separately. But if you decide to buy a new bathroom door, choose a product with already built-in ventilation ducts.

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.

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.

Ventilation in the bathroom: two types of systems and how they work

There are two types of ventilation systems suitable for use in both large and small bathrooms - forced ventilation and natural ventilation.

A forced ventilation system in a bathroom can be an extensive network of pipelines that collect and remove exhaust air from the room. Moreover, this system removes polluted air not only from the bathroom - the kitchen, bathroom, and bathroom can be used in a single network. The heart of such a system is the exhaust fan. Several of them can be installed - each room has its own separate source of movement of air masses.
As for natural ventilation, it looks much simpler, and its operation does not involve any electrical elements (like fans). This system is familiar to almost everyone - in the wall of each bathroom there is an vent for air outflow. The inflow in such a ventilation system can be a gap under the door to the bathroom or a hole in its lower part. In another way, such a system is also called ventilation in the bathroom door.

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.

How do fresh air ventilation valves work in plastic windows?

The device looks like a compact plastic box attached to the top of the window. The box inside is equipped with “feathers”, which regulate the flow of air from the street. In good weather, the ventilation valve in PVC windows allows air flows to pass freely, but as soon as the wind gets stronger, the “feathers” are pressed down, preventing drafts.

The valves automatically regulate air exchange and, unlike forced ventilation, are cheaper, quieter and do not consume electricity.

Types of supply ventilation valves for PVC windows

There are different valve models

1. Seam		2. Slotted
Folded varieties have become widespread. They are so named because air passes along the rebates of the window profiles, entering the valve inlets.	Another popular model is slot valves, in which a wide slit up to 40 cm long and 1.6 cm wide serves as a source of fresh air. In this case, air exchange occurs more intensely.

Both rebate and slot valves can be installed on ready-made plastic windows.

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.

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.

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.

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.

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.

Do-it-yourself ventilation installation in the bathroom

First of all, you need to understand how the installation diagram works. The circuit includes a main air duct, to which branches are connected via tees to take air from the room. This scheme is most often used when installing communications. Installation of ventilation in an apartment or private house begins with the installation of a fan. It can be installed next to the vent or any opening that opens to the street. To prevent air from entering from the house hood, a check valve is installed in front of the fan.

After installing the fan, installation of air ducts begins. Pipe sections and structural elements are connected using silicone or other sealant. The first step is to install the main channel, then connect all the necessary tees and secure everything well. After this, check valves are installed. They are necessary to prevent air from one room from moving into others. Next, the air ducts reach the places where the air intakes will be installed. They are installed only after the suspended ceiling is made. After installing them, you can consider that the ventilation in the bathroom is done.

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.

How to hang vertical blinds

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.

Why do plastic windows sweat?

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.

Recommendations for room ventilation

The advantages of regularly ventilating rooms are undeniable, however, when ventilating by simply opening the doors, disadvantages may appear. Along with the influx of fresh air, noise, dust and sometimes moisture enter the rooms, and the temperature also drops sharply. Since condensation appears on windows mainly in the autumn-winter period, traditional methods of ventilation may not always be convenient and appropriate. That is why it is recommended to give preference to supply ventilation valves or a multi-stage micro-slit ventilation system, which neutralize the listed negative factors.

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.

Types of valves

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

folded;
slotted;
invoices;
valve handle.

Which horizontal blinds to choose for 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).

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.

Fire doors with ventilation grille

These products provide fire protection and necessary ventilation in enclosed spaces. Fire ventilation allows you to organize the safe evacuation of people in the event of a fire and avoid poisoning from dangerous combustion products.

Fire doors with ventilation grilles are installed where constant air ventilation and compliance with fire safety requirements are important. Such objects include:

Enterprises and organizations;
Children's institutions;
Medical institutions;
Securities storage facilities;
Library collections.

Have you ever read about that? You can learn about all the main protection factors and additional means of protection.

Ventilation grilles in the door perform two functions:

Providing air exchange in the room.
Stopping air access in case of fire.

The functionality of the doors is successfully combined with their design: the product organically complements any room interior.

Main advantages and reviews of fresh air valves
