Ventilation grilles for doors to bathrooms, rooms, rooms

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 need for door ventilation grilles

If there is no normal air exchange in the apartment, the well-being of the residents may leave much to be desired. The movement of air from one room to another is usually ensured by a door ventilation grille. This is the best option if the interior door fits tightly to the floor surface.

Purpose of the door grill

Transfer (door) grilles are installed in a hole made in the interior door leaf so that air can move freely between rooms. This eliminates the need to keep the door constantly open. As a result, the air entering through the window will penetrate into the corridor and further into the ventilation shaft. It is advisable to install such products in the following premises:

• Bathroom and toilet, if there is stagnation of humid air, mold may appear there.
• Kitchen. A ventilation grill is needed to provide air access to the hood.
• In other rooms, if there is no gap under the door.

Such products can be used in premises for any purpose, not only residential ones.

Material and shape

Usually rectangular-shaped products are produced, but there are round and even square door ventilation grilles. The model includes two frames. The inner one, on which the slats are placed, is installed in the door leaf. The shape of the slats is V-shaped, allowing air to pass through, but blocking visibility. The outer frame performs a decorative function and is installed on the back side of the door.

Transfer ventilation grilles are often made of plastic; they are very practical and cheap. A metal door ventilation grille is also available, but it is better not to install it in bathrooms if the metal is not stainless steel. Ventilated grilles are often powder coated to protect them from moisture. In the production room you can find any models of gratings.

Transfer grilles AP (for doors and interior partitions)

Transfer aluminum ventilation grilles AP are designed to redistribute air between rooms. Transfer ventilation grilles consist of two rectangular frames - external and internal. V-shaped horizontal blinds are fixedly fixed in the inner frame, obstructing the view through the grille. The outer frame is installed in a door or wall opening and secured with self-tapping screws. The internal frame of the ventilation grille is installed on the opposite side of the door or wall. The dimensions of the frames allow the installation of grilles on doors or walls with a thickness of 25 to 50 mm.

The flow ventilation grilles are made of aluminum and powder coated in white (RAL 9016). When making custom-made gratings, it is possible to paint them in any color according to the RAL catalog or texturize them.

The minimum size of the ventilation grille is 100 x 100 mm, the maximum is 1000 mm on one side, pitch 50 mm.

Data for selecting transfer aluminum ventilation grilles AP when supplying air to the room

* It is possible to produce custom aluminum ventilation grilles for doors of other sizes and colors. For more detailed information, please call in St. Petersburg (812)680-30-82.

Fastening with glazing beads or plinths

This method is used infrequently and is typical for rooms with wooden flooring.

For installing a ventilation grille by tightly fitting it using glue or clamps directly into the hole itself, it is quite easy to perform. For such fastening, assembly adhesive, silicone or liquid nails are suitable. Using a special glue gun, glue is applied with a small protrusion above the depression along the entire perimeter. Next, the grille is applied to the mounting location - the wall, and fixed. After 24 hours, the glue dries and the grille is securely fastened. It must be remembered that the wall must be dry before installation, and the fixation with glue must be without gaps.

As a rule, an industrial grille is attached using spacers on a spring to a prepared hole. This method is simple and does not take much time.

Do not forget that for residential premises it is worth choosing ventilation grilles made of environmentally friendly materials that are harmless to the human body. If the grille is located outside, the material must be weather-resistant.

Types of ventilation grilles

Depending on the location of installation, the gratings are divided into:

• external, installed on the external wall of the building at the exit of the ventilation hole;
• internal, usually located in the kitchen, bathroom and toilet in the openings of exhaust shafts;
• wall or door overflows that regulate air exchange between adjacent rooms.

Outdoor models are usually characterized by high strength, resistance to external weather conditions and relatively large weight. They are equipped with a rigid frame that fits inside the ventilation hole and is secured with anchors or factory spacers. This method ensures maximum reliability of installation and durability of the part.

Products for indoor installation are often chosen for aesthetic reasons. They are distinguished by their light weight, pleasant appearance and small size. In the bathroom it is better to install a ventilation grille made of lightweight waterproof materials.

Supply ventilation in the bathroom

If the natural exhaust system does not cope with its duties, a fan is installed in the bathroom. What to do if there is no influx? After all, in order for a fan to extract air from a room, it is necessary for that air to enter it. As you know, supply ventilation of a toilet or bathroom, and in most apartments, occurs naturally - through cracks in the doors. If your doors are very tight, there will not be adequate air flow. For normal flow to the toilet or bathroom in such cases, it is necessary to keep the doors open, which not everyone will like. Especially if you consider that the exhaust fan works when you take a bath and the influx is needed precisely at this moment. Therefore, for the normal functioning of fresh air ventilation in the bathroom, “door ventilation” is used.

The importance of proper air exchange

Air replacement is necessary for the following reasons:

• regulates humidity levels and temperature fluctuations in the room;
• ensures proper circulation and flow of fresh air into living spaces;
• removes toxic substances from the room.

Currently, finishing materials have high water and heat insulation properties. Therefore, ventilation grilles are increasingly being installed in doors to remove expired air and moisture from the room. Or choose any other design that needs some space. Otherwise, high humidity is created in the bathroom and toilet, which leads to the formation of fungi, mold, and destruction of plumbing products and finishing materials.

Insufficient ventilation in a room negatively affects the health of people in it:

1. Suffocation occurs;
2. fainted;
3. dizziness;
4. Drowsiness;
5. fast fatiguability.

Over time, a person may develop a chronic lack of oxygen. To avoid these problems, perform air exchange calculations and install high-quality products for room ventilation.

Purpose and role

In fact, the ventilation system is one of the most important engineering structures of any house, regardless of whether it is private or multi-apartment. It is ventilation that is responsible for proper air exchange, as well as for comfortable climatic conditions in each individual apartment or room. The system has its own ventilation ducts, at the inlet and outlet of which a grille is mounted.

It performs several functions at once, namely:

• protects the mines from possible clogging, as objects and animals may accidentally fall into them;
• correctly distributes air flows, especially for supply-type ventilation grilles;

Main varieties and purchase

The decor of the fireplace directly depends on which grate you choose. In turn, they can differ greatly from each other. The main difference is in the form, which can be:

1. Rectangular;
2. Square;
3. Round;
4. Oval;
5. Wrong.

The openings and gaps of ventilation grilles can be:

1. Slotted;
2. Round;
3. Square;
4. Rectangular;
5. Incorrect;
6. Tunnel.

When purchasing a ready-made grating, it is important not only to choose the most suitable shape, but also its dimensions. This is necessary for proper circulation of heated and cold air flows

You can calculate the dimensions of the grate and its holes based on the dimensions of the combustion compartment itself.

Ventilation in the toilet or bathroom door

As a rule, a classic of the genre when renovating is the following rule: a small opening is left between the floor and the bottom of the door to the bathroom, which is intended for natural ventilation. However, many homeowners do not fully appreciate the necessity and necessity of this opening, and recklessly seal it up during repairs. Most homeowners build a special threshold, install a seal, and so on, citing the fact that when flooding, water will not spread throughout the house.

Taking this trend into account, modern bathroom door manufacturers are making doors with a built-in ventilation hole. These can be either simple holes or ventilation grilles. The first option is simpler and less aesthetically pleasing, while the second looks harmonious in the space of the door. The holes are designed in such a way that it is unlikely to be possible to peek from the other side of the door, which will not in any way affect the intimacy of the bathroom space.

Door device options

There are doors with ventilation grilles and rings. In the first case, an opening is cut out at the bottom of the canvas according to the shape of the product and covered with a plastic, metal or wooden lattice. The advantages of such designs include:

1. large range of products;
2. opacity;
3. lack of draft, since there are obstacles to the movement of a continuous flow of air.

Such products are installed across the entire width of the door or in several places. It all depends on the interior design. During installation, the grille should be installed strictly parallel to the floor.

Another way to organize ventilation is to form rings in the door. This one differs from the previous version only in the absence of strips. A plastic or metal ring called a bushing is inserted into the hole. It allows you to protect the canvas from moisture and dirt. From an aesthetic point of view, this option looks better.

Basic installation methods

Installation of the ventilation grille does not require special knowledge and skills. It can easily be done by a home craftsman with patience and accuracy. Most industrial products consist of two parts:

• main body, mounted directly on a hole in the wall or door;
• a removable part inserted into the openings of the housing, which allows you to inspect and clean the channels of the ventilation system without any problems.

Begin to hang the internal ventilation grille from the first part, which plays the role of a frame. This is done using fastening materials or adhesives. Before this, the outer surface of the ventilation hole is prepared accordingly. It should be smooth and clean. Typically, the grille is placed on the wall after the finishing coat has been applied to it. This can be done in different ways:

1. Fastening with screws or self-tapping screws is carried out on a solid wall made of concrete, wood or plasterboard. To do this, through holes are drilled in the grill body in places covered by the removable part, which are countersunk to the shape of the cap. You will have to install dowels in concrete or brick in appropriate places using a drill. When constructing a grating without a removable part, after installation, the screw heads are puttied and painted to match the color of the base material.
2. Fastening with plinths or glazing beads is usually used for wooden products that fit well into a country-style interior made entirely of wood. In this case, self-tapping screws or finishing nails with a reduced head size are also used.
3. Industrial models with standard spring-pressed spacer elements included in their device can simply be inserted into the ventilation hole, which must have standard dimensions for this.
4. The easiest way to attach a plastic grill to any base is with glue. This is especially true for walls lined with fragile materials such as ceramic tiles. For this, compositions such as “liquid nails” are usually used. They are applied in a continuous stripe to the back side of the part, which is pressed against the wall and fixed with masking tape until completely dry. In this case, it will no longer be possible to dismantle the fragile part without destroying it.

The removable part of the grille is tightly inserted into the base fixed to the wall. In this case, for aesthetic reasons, it is better to rotate it so that the holes between the slats of the blinds are not visible to a casual observer standing on the floor of the room

When selecting and installing the transfer grids, pay attention to ensure that light rays do not directly pass through them. This can reduce sound insulation and does not look very nice

Plastic models usually include a thin mesh, which quickly becomes clogged with dust, reducing the effectiveness of the ventilation system. That's why most craftsmen don't install it. Otherwise, you will have to regularly clean the mesh.

DIY installation

To do the installation yourself, you will need to prepare the following tools:

• Ruler and pencil;
• building level;
• drill;
• jigsaw;
• assembly adhesive or self-tapping screws;
• bits of the appropriate diameter for the drill;
• chisels;
• sandpaper;
• screwdriver.

Since the product is extremely simple in design, there is no need to use any special tools. To complete the installation, you need to perform the steps in this order:

1. Measure the rings or grid. Measurements should be taken along the inner part that will be inserted into the door.
2. Mark the canvas. It is advisable to add 1-2 mm on each side so that the product fits easily into the groove.
3. Using a drill, holes are drilled in the canvas. If a rectangular grille is installed, make holes in the corners. Then the canvas is cut along the line with a jigsaw. When the device has an oblong shape, the opening should be selected in the door using a chisel.
4. The cut areas are cleaned with sandpaper and then varnished.
5. The rings are fixed with glue, which can be bought at any hardware store. PVA is also used. They need to be installed exactly level, since once the glue has hardened it will be difficult to make corrections.

The simplicity of the products and installation allows you to do the installation yourself. The main thing is to choose the right grille so that it fits harmoniously into the design of the room.

The most common grating options

The most common type is a plastic supply and exhaust grille. It is intended for wall or ceiling installation, promotes high-quality air distribution throughout the room and is used for decorative purposes.

This grille includes additional elements - latches for the removable inner part. Mounted with screws. Some models have inclined slats.

Supply and exhaust

You can also find plastic exhaust models. Serve for outdoor installation and decoration of the exhaust vent outside the house. Such models are mounted using screws and include blinds that serve to prevent reverse draft.

Often a combined type of grille is used, designed to connect the hood in the kitchen and for general ventilation of the apartment. The material used is durable plastic. The design includes a deviator that prevents backdraft through the bottom. Installation is carried out using screws. Cleaning channels with such a grille is not difficult, since its lower part is removable.

Door grilles are mounted at the bottom of the door and allow free movement of air between rooms. The material used is durable plastic. To protect against insects, a mesh is used, which is mounted with screws.

Door grill

Round grates

Round grilles for doors
The design of round grilles 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.

Varieties

Adjustable ventilation grilles are classified according to the location of installation and are external, internal and transfer.

Outdoor models are installed on air ducts on the outside of buildings and are often equipped with mosquito nets and a heating function. These products are further divided into several types:

• front grilles are designed to ensure ventilation of attics and are distinguished by an extended decorative edging;
• base models are installed on basement ventilation ducts and are characterized by a durable design and protection from rodents;
• door grilles act as a check valve and are used in natural supply systems;
• floor-standing models are installed in ventilation systems that supply air into the room from below, and are characterized by high strength and wear resistance.

Indoor models are installed indoors and are available in several modifications.

• Kitchen models. Such grilles are equipped with a check valve and have inertial louvers, which completely eliminates the reverse flow of exhaust air into the room.
• Fireplace models are used to circulate warm air from fireplaces or stoves into adjacent rooms.
• Slotted grilles are usually installed under the ceiling or placed between interior items. The models are distinguished by their small working surface dimensions and are practically invisible during installation.
• Overhead traditional models are used in any room and are distinguished by their modern design and low cost.

The gratings differ in the material they are made from. The lightest and most inexpensive raw material is plastic. Plastic models have a wide range, a wide variety of colors and aesthetic appearance. The disadvantages of such products include the inability to operate in conditions of high and low temperatures, as well as the likelihood of color models fading. It is worth noting that, in addition to plastic, brass, galvanized and chrome-plated steel, as well as aluminum are used to make grilles.

Metal grilles are characterized by a long service life and trouble-free rotating mechanism of the blinds. The disadvantages include heavy weight and the likelihood of rust. The most expensive and attractive are models with wooden cladding. The frame and blinds in such products are made of metal or plastic. Wooden options have an unusual appearance and are used for indoor installation.

Criteria for choosing window ventilation valves

For effective operation of the fresh air damper on plastic windows, the versatility of the device is necessary. To determine the class of vent valves, the following critical features exist:

• Provide the necessary air exchange parameters: The valve must operate with an external air supply of at least 30 m3 / h (per 1 person).
• Ensuring the required noise level: for standard plastic windows, this indicator is set to 30-35 dB.
• Specifics of winter operation: this parameter depends on the material of the valve structure, the difference between external and internal temperatures, and air flow parameters. For efficient operation of ventilation fittings and prevention of icing, it is important to maintain high quality thermal insulation of the fitting structure and use a so-called “thermal spacer” made of plastic between the outer and inner surfaces of its metal body.
• Type of regulation: it is possible to install a supply damper for plastic windows with automatic, manual and mixed regulation (tandem of the two previous types).
• Valve location: Installation options on windows and walls are possible. Installation on the wall significantly increases the cost of punching holes in the building envelope and disrupts the appearance of the facade due to the appearance of foreign elements. The window version is more economical, simple and discreet.
• Installation method: installation on an existing plastic window with insulated glass or replacement of the window with a double-glazed unit with insulated glass of a new smaller size.

Note: Valves not equipped with a control option should not be considered as the need to change the air supply is dictated by practice.

Attics - life under a roof

There is no doubt that the attic space should be insulated, otherwise there will be no comfort and coziness in the building. With good attic ventilation, fungus and mold will not appear, so the service life of the roof is significantly increased.

Ventilation helps proper heat exchange. In summer, the sun heats the roof up to 100°, and other rooms are heated by the attic. And in cold climates, condensation appears in the attic. This causes humidity to increase and wooden structures begin to rot.

Attic ventilation diagram - simple and clear

The ventilation system does not allow air to stagnate in the attic, but constantly mixes it with the outside air, because of this there will be no icicles and ice in the room.

Methods of regulation

Depending on the design of the valve mechanism, the flow of supply air on ventilated plastic windows can be adjusted or have constant parameters. Optimal indoor climate conditions can be created using a manual or automatic valve. The latter is more convenient, based on a humidity sensor that monitors the humidity value in the room. The humidity sensor measures air flow by changing the cross-section of the opening until the duct is completely closed. The maximum cross-section corresponds to the highest humidity value. This type of control reduces heat loss because the air is only ventilated when people are in the room and the humidity in the room is increased. When the room is empty and the humidity decreases, the valve closes completely.

Choosing a manual control method involves constant thought about how long to ventilate, in what order to ventilate the room, and when to open the valve needed to ventilate. Manual controls can only restrict airflow in gusty winds. This setting is coarser and may cause drafts in the room.

Types of adjustable grilles

There are several types of classification, based on which you can choose the optimal design for yourself.

Since the ventilation grille with louvers is the final element of the entire system, first of all you should consider the classification according to the installation site.

At the installation location relative to the street

Based on the installation location, they are divided into:

Internal. Installed at the point where ventilation pipes exit into the interior. Such devices must regulate both the strength and direction of the flow.

An aesthetic appearance that harmoniously fits into the interior of the room is also important to them.

External. Installed on air ducts outside the building. They must have increased wear resistance and also be resistant to moisture and low temperatures.

It is important to understand that they can be affected not only by unfavorable environmental factors. In some cases, heating is installed on them to prevent the formation of ice.

Transfer

They are installed in interior ceilings, as well as in doors located indoors. Their main function is to distribute air inside the building.

Transfer. They are installed in interior ceilings, as well as in doors located indoors. Their main function is to distribute air inside the building.

At the place of installation in the house

Floor ventilation
Frontal models. They are installed in attics or attics. A characteristic difference is the extended decorative edging.

Base type. This type of ventilation grille is used to supply air to basements

In this case, it is important to provide protection from rodents, so a metal adjustable structure is often used

The size and shape are strictly regulated. This type is available only in the shape of a rectangle with side dimensions of 15.24 × 37.5 cm.

Door ventilation. It works on the principle of a check valve.

Floor adjustable grilles. Installed on ventilation to supply air masses from bottom to top.

According to the specifics of installation

Slit ceiling ventilation

Based on the specifics of installation, adjustable ventilation grilles are divided into:

Adjustable exhaust and supply ventilation grilles of overhead type. Can be installed without restrictions in any premises. The flow is adjusted using lamellas.

Installed in the kitchen. They must have a check valve to prevent the spread of unpleasant odors.

Slotted. Their main advantage is invisibility. They are mounted under the ceiling or hidden with decorative interior details.

Fireplace supply units. Their main function is to supply warm air from the fireplace to other rooms.

Depending on the installation location, the products have different requirements.

According to the material of manufacture

There is also a classification according to the material from which the products are made:

Aluminum. Distinctive characteristics are low weight and high strength. However, during use they darken. The rather high cost is also not an advantage. To improve the appearance, a decorative coating is applied to such products.

Steel structures. The most durable of all offered in stores. They are well suited for both outdoor and indoor installations.

Disadvantages include susceptibility to oxidation. Stainless steel products do not have this drawback. However, such products are much more expensive.

Plastic adjustable ventilation grilles. The most popular materials: polystyrene and PVC. They are mainly used indoors, although outdoor installation is also possible.

They are light and cheap, but over time they lose their attractive appearance. Microcracks also begin to form on them. Because of this, the service life of the product is short.

Wooden. Used for decorative purposes. If the interior is dominated by wood products, then other materials will look ridiculous. Most often used in the construction of baths and saunas.

By design

The gratings are also divided according to their design:

• Products with blinds (adjustable and non-adjustable).
• Inertia ventilation type. They are equipped with gravity blinds, which close automatically when there is no air movement.

The shape of ventilation adjustable blinds can be round or rectangular. Round ones are more efficient, but rectangular ones are easier to install.

Why is apartment ventilation needed?

Ventilation of residential premises in most multi-storey buildings (both new and old, especially in Moscow) is carried out using exhaust vents, which the investor equipped the building with during its construction. Exhaust hatches can be seen in the kitchen, toilet and bathroom. The ventilation system of each apartment (in the kitchen and bathroom), like all other apartments, is directly connected to the central air duct. The ventilation duct starts in the basement and passes through the ceilings to the technical floor of the building, from where it is discharged outside.

The movement of air masses in central ventilation is caused by the difference in temperatures of external and internal air. Heated air masses are sucked from the apartment into the central air duct through ventilation hatches inside the apartment. Clean air is sucked in through the windows and doors of your apartment. This ventilation system existed before the widespread installation of sealed polyvinyl chloride (UPVC) exterior windows and doors.

Currently, due to the installation of window units and doors with increased tightness, the supply of clean air is severely limited, which leads to a deterioration in normal air exchange in a residential area. Dirty air in a living space is a sign of problems with the ventilation system. Deficiencies in air exchange can be corrected by installing window frames with a ventilation function, but in this case, installing a PVC structure becomes pointless (sound insulation deteriorates and street dust begins to penetrate). If, in spite of everything, we decide to install plastic windows, it would be nice to equip the apartment with a fresh air ventilation system.

Ventilation in a living space is necessary:

1. Freshen the air in the room.
2. Don't let dust or noise from outside enter your home through an open window.
3. To introduce fresh outside air into the home.
4. To stay awake in the morning.
5. There were no drafts and much more.

Before installing your first bathroom door, make sure it is ventilated—whether it allows air to pass on its own, and if not, whether you can install grilles or vent rings. Find out also what are the optimal door sizes for a bathroom.

There are the following material options for bathroom doors:

• Glass. Frosted glass doors are great for wet areas - they are resistant to moisture and heat, and they look great on top. They also easily withstand a lot 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 doors in advance, they will not let air through.
• Plastic. The cheapest option, inferior to analogues in aesthetic characteristics. Like glass, it can withstand all aggressive influences. With certain skills, you can equip such gates with a ventilation grille.
• Solid wood. It withstands humidity and temperature fluctuations the worst, but is best suited for door ventilation.
• Wooden products - laminate, chipboard, MDF - when protected with special impregnations, tolerate moisture well and it is easiest to install ventilation in them. Like the plastic models, this option is quite cheap.

Therefore, despite the low resistance to moisture, wooden options are better suited for organizing a constant flow of air - then you can even make cut ventilation grilles for bathroom doors yourself.

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:

1. 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.
2. 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.

Installation of a surface-mounted fan

In small bathrooms, removing humid air is much easier. To do this, simply install a standard surface-mount fan. The most important thing is to correctly determine the required power of the device, otherwise all efforts may be in vain. For a rough estimate, experts recommend using the following formula: the area of ​​the room should be multiplied by 6 if the room will be regularly used by less than 3 people, or by 8 if more than 3 tenants live in the house. The value obtained in this way will correspond to the required power of the device.

The device is installed with the power off. Start by attaching the floor box. Then connect the contact terminals to the mains using a two-core cable with a diameter of approx. 0.2 mm. Then you can begin installing the device body. Usually it is equipped with special latches, so it does not require additional fasteners. Upon completion of work, the effectiveness of the installed devices is checked. Surface fans differ from each other in design, but are assembled in accordance with the described scheme.

Types of exhaust grilles

Metal and plastic types of ventilation grilles, depending on the purpose and location of installation in the air duct, are: exhaust and supply. Depending on the installation location, these products are:

• external;
• internal;
• interchangeable.

Domestic

One of the most popular types on the market. Taking into account the features of functioning and fastening, they are:

overhead – used primarily in residential buildings, in systems where natural draft predominates. The presence of a mosquito net prevents insects from entering the premises. They are often equipped with a check valve. The throughput can be adjusted using movable slats;

• slot models - installation of ventilation grilles of this type is in demand primarily in areas where it is necessary to ensure the inconspicuousness of the product. Their design and appearance matches the room;
• models with check valve. Popular solutions equipped with inertial blinds and a reverse draft valve. Often used as a functional element for an exhaust device.

External

External products are available for sale in several types of designs:

• frontal models – installed mainly in attics. They are distinguished by a wide edging and a magnificent appearance;
• door models – functionally replace the supply valve, which is primarily relevant for those rooms where it is necessary to ensure natural air supply;

• floor-standing models are an ideal solution for organizing the supply of fresh oxygen to the lower part of the room. These can be fixed or adjustable solutions;
• plinth grilles - used primarily as a protective element against rodents. Installing a ventilation grill will protect basements, attics, and basement floors from small pests.

Internal transfer

As for internal transfer options, they can be different not only in color, but also in shape. They feature an attractive design. Among professionals, products of round and rectangular shapes are primarily in demand. Their main feature is the absence of valves.

Fireplace protective elements are widely used in fireplace rooms, which ensures the supply of heat to the room. The penetration of cold air masses is carried out through the lower part of the grille, and after warming it is redirected into the room.

Installation of several ventilation grilles within one fireplace is an important component of effective air exchange.

Note! Fireplace models are made from refractory and fireproof materials. Considering the variety of patterns and shades, they are classified as decorative

Combining ventilation and windows

People who care about their own health are wondering about the possibility of maintaining proper air exchange in an apartment with plastic windows.

There are many options for upgrading natural ventilation systems in residential buildings. Some of the most effective methods are those that are installed on the double-glazed windows themselves or are already attached to the window structure at the factory.

Windows with a window

The ventilation system for PVC windows, for example, from such companies, is most often used with a fan. Ventilation ensures a constant supply of clean air. It mixes with the air removed from the room, diffusion occurs, which normalizes the microclimate.

Natural ventilation prevents drafts and condensation on windows. The window sash can be fixed in several positions. However, this design has many disadvantages:

1. Ventilation for plastic windows is installed at the design stage of the window opening. Improving ventilation after installing the entire structure is impossible.
2. Such ventilation of plastic windows significantly increases the weight of the structure, which can negatively affect the house itself. Cracks may appear in the walls and window openings of a private home, so it is better to consult with specialists from a construction company before calling an appraiser.
3. Adding a vent increases the cost of the structure.
4. Increasing the plastic partitions in the window frame darkens the structure, and the light in the room becomes much less.

Plastic windows with self-ventilation

Plastic windows with a ventilation system using a self-ventilation system are the best solution for both residential buildings and private houses. A fan for plastic windows is also installed in industrial buildings, as it supports the operation of the main ventilation system.

Such ventilation in NRPVC windows is represented by slot holes in the upper or lower part of the NRPVC window frame. This slot ventilation ensures a constant flow of clean air into the room through the openings. And thanks to the special arrangement of the holes in the frame, cold air is heated and enters the already heated room.

Self-ventilation in windows has several disadvantages:

1. This ventilation mode does not work in apartments on the upper floors and in private multi-storey buildings. When installing ventilation after a home has been built, careful consideration must be given to how to improve ventilation on higher floors without using this method.
2. This ventilation system cannot be installed in already installed double-glazed windows, so the entire window structure must be changed.
3. High cost of self-ventilating windows. Manufacturers increase costs threefold or more due to the complexity of the production conditions of such structures.

Therefore, most people resort to using specialized ventilation valves in the form of plastic window handles or combs.

Ventilation in a private house with plastic windows is mandatory if the homeowner cares about the health of family members.

It is necessary to regularly ventilate the apartment, especially if another ventilation system does not give the desired effect. The best way to normalize air exchange in an apartment is to install ventilation valves on plastic windows.

The ventilation valve combines several functions, and for proper ventilation it is necessary to select the desired class of device.

Installation of the valve requires complete dismantling of the double-glazed window or replacement of the part of the window responsible for ventilation. Such modernization makes the structure heavier and significantly affects the cost of the window. However, installation takes place in less than an hour, and air exchange is normalized within 24 hours, which indicates the undoubted advantage of this design.

After installing the air intake valve, you will need to decide whether you want automatic, manual, or mixed control.

Manual ventilation mode allows the owner to independently control the movement of air masses in an apartment or house. Partial ventilation can be used in those parts of the house where it is really needed.

And in automatic mode, no owner participation is required. As soon as the sensors in the valve respond to a change in temperature, the system supplies fresh air. The temperature returns to normal, and with it the air exchange.

Mixed mode valve control allows you to switch between manual and automatic control as needed.

Handle valve for plastic window

Air exchange in sealed structures can be improved by installing a special valve with a window handle.

The handle with the valve is installed in the window profile instead of the traditional plastic handle. This installation system has many advantages:

1. The damper does not protrude beyond the window profile, does not load the structure and does not interfere with the free opening of the window.
2. Condensation often collects in places where the window profile is most vulnerable. The handle is drilled directly into the profile itself, and condensation collects there. The presence of a valve handle eliminates the formation of condensation and improves air exchange in the cold season.
3. When using forced ventilation, installing a damper will create additional comfortable conditions and completely eliminate stagnation of exhaust air.
4. The manual valve is a design with a direct flow of clean outside air into the room. With direct air supply, the valve does not freeze in winter due to the absence of condensation.
5. Only purified air will be sucked in from the street, since an air filter is installed on the valve, which can even remove allergens. Such a filter will not cause much trouble: even in a stuffy metropolis you will not have to change it more than a few times a year.

This method is new in the world of ventilation systems for PVC structures, so not all professionals know about its existence and the possibility of its installation.

However, this does not mean that installing a manual valve in itself is difficult. You can buy a template from large DIY stores and instructions are always included with it. By following the rules for assembling and drilling the profile, you can easily install a ventilation hole in a few minutes.
