Ventilation in the window sill: methods and detailed instructions for arranging window sill ventilation

Installation steps and rules

Do-it-yourself installation of a ventilation grill can be done in a plastic or wooden window sill - installation in a concrete "board" will require much more experience and other tools. Otherwise, the grille is mounted in the concrete window sill in the same way.

Consider the nuances and stages of work for a plastic or wooden board and the same lattice. It is not necessary to remove the window sill for work. The direction of the slats (if the holes are slit-like and the slats are installed at an angle) should be towards the window.

Cut a hole in the window sill for the ventilation grill

From the tools you will need:

Marking tool (marker, pencil).

Electric jigsaw or grinder.

Adhesive for plastic (not required).

Any heavy object that can be used as a press (needed if the grating will be glued).

The diameter of the drill for the drill must be greater than the width of the blade of the jigsaw (so that it can crawl into the drilled hole).

Stages of work

The process itself looks like this:

The place where the lattice will be located is marked.

Holes are drilled in the corners.

A jigsaw blade is inserted into the hole and a landing hole is cut out under the grate itself.

The product is installed in the hole - for "trying on".

The edges of the hole are coated with glue.

The grate is put in place and pressed.

The glue squeezed out along the edges is removed.

Any heavy object is installed on top of the grate - as a press.

Hole in the window sill for grating

Metal products (as well as some plastic and wooden ones) are attached not to glue, but to bolts.

The use of glue is not an ideal solution - in this case, the design will turn out to be one-piece. If necessary (for example, if the plastic lamella breaks), the grate will have to be torn off from the surface.

Glue can be omitted if the groove is perfectly even: so that the grate “sits” tightly in it without moving. In this case, if necessary, it can be pulled out - for replacement, repair or cleaning.

A kitchen with a combined table and window sill looks incredibly stylish. An additional work surface in front of the window and the absence of bulky radiators are now in vogue. But in such a situation, you have to cut a hole in the countertop for the passage of warm air. You can effectively close such an opening with the help of a decorative metal ventilation grill in the countertop.

Benefits of forced ventilation

The widespread fascination with plastic windows is explained by the desire of people to reduce heat transfer in the cold season and maximize heat retention. However, this also leads to difficulty in natural air exchange due to the tightness of windows with fiberglass packages. At the same time, waste products accumulate in the apartments - carbon dioxide and excess moisture. Considering that each person releases approximately 20 liters per hour. carbon dioxide, then in the absence of forced ventilation in an apartment with plastic windows, the concentration of harmful substances in the air exceeds all permissible sanitary and hygienic standards.

To ensure a comfortable, safe environment for the inhabitants of the apartment, the air exchange indicators must be no less than those given in the SNiP.

According to paragraph 31-01-2003 "Residential multi-apartment buildings", the air exchange rate is:

• For living rooms at the rate of up to 20 m2 of total area per person - no less than 3 m3 / h for each meter of living space;
• 30 cubic meters of air per person per hour, if each person has more than 20 m3 of total area;
• For premises using gas equipment (gas stoves, boilers) - 100 cubic meters of air per hour;
• For a kitchen with an electric stove - at least 60 m3 / h;
• For a bath, toilet or combined bathroom - 25 m3 / h.

List of Benefits

It is possible to ensure the regulatory requirements for providing residential premises with an influx of fresh air only by using forced ventilation.

The benefits are obvious:

• Forced ventilation does not depend on the season or the weather;
• Does not require complex engineering calculations when laying communications;
• Allows you to ensure the flow of the required volume of air into all living rooms and exhaust from rooms with high humidity, gas pollution and lack of natural ventilation (kitchen, bathroom, pantries, wardrobe, utility rooms);
• Helps to mix the indoor air with the incoming dry air, thus reducing the possibility of condensation.

Many apartment owners, where the usual wooden frames were replaced with fiberglass bags, complain about the formation of condensate. This is due to the occurrence of the so-called "dew point" - when the surface temperature of walls and windows drops to the level necessary for condensation to form at a certain humidity. The higher the air humidity, the higher the dew point temperature.

So, if the air temperature inside the room is +18 degrees Celsius, and the humidity is 50%, the dew point is 6.8. With an increase in humidity to 75%, this figure increases to 13.2. That is, with an increase in the humidity of the air inside the room, the indicator of the ambient temperature, favorable for the formation of condensate, increases.

It is possible to avoid such a phenomenon for an apartment equipped with plastic windows by providing forced ventilation of the supply and exhaust type.

How to embed a grate in a window sill: instructions

Installing a plastic grate in a plastic or chipboard window sill is quite simple and anyone who knows how to work with a “grinder” and a jigsaw can handle this process. In this case, the scope of work will be approximately as follows:

Make a markup on the windowsill - circle the bottom of the lattice with a pencil.
To make the lines even, correct with the help of a regular school ruler.
"Bulgarian" or electric jigsaw, along the marked lines, make cuts.
Remove the cut out part of the window sill.
Sandpaper to process the cuts, removing sharp burrs

Carry out the work carefully, without scratching the window sill itself.
Insert the grille into the slots in such a way that the blinds “open” towards the window frame and warm air is directed onto the glass.
The grid can be glued on polymer glue. But, in order not to complicate the care of her, it is recommended not to strengthen in this way

Such installation is not mandatory and therefore its implementation depends on the preferences of the customer.
Before the final installation of the ventilation grille, collect the dust from cutting holes with a vacuum cleaner.

You can mount the ventilation grill in a window sill made of plastic or wood with your own hands. Stone, concrete and other window sills - it is better to entrust qualified specialists.

Varieties of supply valves for apartments

Today on sale you can find many varieties of supply air valves - with heating, filters, fans and other functions. However, the main difference between devices of this type is the installation features. On this basis, supply ventilation valves are:

• window - installed inside the frame of the double-glazed window;
• wall-mounted - mounted in a special hole in the wall.

Both of these types have their advantages and disadvantages. In this section, we will analyze their differences in detail and try to make it easier for our readers to choose the right model.

Window models of ventilation valves

There are ventilation valves that are mounted on plastic windows.This provides good ventilation even in winter, when it is problematic to open the window due to too cold air outside.

The window inlet valve has excellent aesthetic characteristics, it is almost invisible on the frame of the double-glazed window. At first glance, this design seems to be the most acceptable for any home, but it has a number of disadvantages:

• high cost compared to wall counterparts (sometimes the price of a valve reaches 50% of the price of the double-glazed window itself);
• the valve is installed before or during the installation of a plastic window; it cannot be placed in a closed window opening;
• installation is carried out only by professional craftsmen;
• window valves, as a rule, are not equipped with filters and heating.

Wall ventilation valves

The supply valve installed in the wall is a simple and inexpensive, but very functional device. It is a plastic sleeve in which the filter and noise protection are installed. From the outside ventilation valve in the wall equipped with a mesh and rain protection, with an internal - decorative grille, in which a damper is mounted.

The wall supply valve compares favorably with window analogues and natural ventilation in the following parameters:

• low price, no need to buy a device with a window;
• better protection against noise and dirt;
• works great in winter;
• possibility of automatic or mechanical control;
• provides ventilation throughout the apartment.

The main disadvantage of the wall model is that to install it, you will have to make a hole in the wall of the house.This process is quite time consuming, but not difficult, from a technical point of view, anyone familiar with repair work can handle it. From the point of view of aesthetics, mounting the valve on the wall will not cause any particular trouble - both in the apartment and on the outer part of the wall, decorative shutters will make the device almost invisible.

Hardware stores offer customers a large selection of inlet ventilation valves into the wall. The design of the device is quite simple, so devices from different companies do not have serious external differences. The main one is the length and material of the ventilation duct pipe. All valves are equipped with a barrier that regulates the air flow into the room. Up to 40 m³ / h of air masses can pass through the device, this is quite enough to completely ventilate the apartment.

Developers supply supply valves with a whole range of additional functions. The first of these is the ability to control the air flow regulator. This makes it possible to provide airflow in conditions when ventilation of the room is especially necessary, for example, if damp laundry is being dried in the room or food is being prepared.

Management can take place in automatic or mechanical mode. In the first case, the device itself monitors the temperature and humidity of the air in the room and adjusts the level of the pipe barrier. In the second, the device is configured manually by the owners.

Valves on automation are more expensive than their counterparts, but they do not always correlate well with weather conditions. If in winter the automatic control function is very relevant, then in summer at the same temperature outside and inside the premises, it practically loses its significance.

Window sill ventilation methods

Depending on the initial depth of the window sill, the thickness of the outer wall and the depth of the window frame, there are two ways to ensure air circulation near the double-glazed window:

• using the natural passage of flows through the holes made in the window sill for ventilation;
• thanks to the installation of a separate ventilation duct with an inlet valve.

Each of the methods has its own characteristics both in the selection of materials and in implementation.

Ventilation through grille openings

The first method of improving air passage is quite simple and does not require special skills.

Even an inexperienced craftsman can make the necessary holes and fix the ventilation grill. The method is suitable for window sills of medium and large depth, the protruding part of which significantly overlaps the radiator. Ventilation grilles will allow air to pass through the window sill more freely and to flow to the double-glazed window in sufficient quantities.

The grilles themselves can be made of different materials: plastic, aluminum, steel and even wood. The most ergonomic are metal products coated with a special paint that is resistant to high temperatures. Plastic is found on sale no less often, however, this material can deform over time and lose its original shade, which also will not add aesthetics to it after a year of operation.

The dimensions of the grille for ventilation are selected based on the width of the window sill. In order for the window to warm up more evenly, it is better to install the grate along the entire window sill.

Particular attention should be paid to the living section of the grate - the size of the holes through which air will pass.The larger their area, the more efficient the circulation will be. The slats themselves can be static or adjustable.

The second option is more preferable for installation, as it allows you to more accurately adjust the angle of air direction or completely block the air exchange

The slats themselves can be static or adjustable. The second option is more preferable for installation, as it allows you to more accurately adjust the angle of air direction or completely block the air exchange.

Installation of a channel with an inlet valve

A more complex method that requires more skill during installation and knowledge to select a special complex - a window sill valve.

The method consists in arranging a special window sill ventilation system, which consists of:

• an inner box with gratings through which the exhaust air is taken;
• a ventilation duct in the form of a pipe that brings the flow out;
• external grille with filters that do not let in street dust.

The slats of the house box are usually adjustable, which allows you to change the intensity of the air intake. The channel itself is equipped with additional filters and reliable sound insulation, which will prevent too loud sounds from outside from penetrating into the room.

The design can also have an engine that will provide a more efficient capture of street air. To reduce heat loss, it is worth looking at devices with heat recovery.

Such ventilation systems are optimal for houses and apartments with thick walls and deep window sills.

The main advantages of the designs are:

• maximum and constant renewal of air in housing;
• the ability to avoid sudden changes in temperature or drafts that may occur when airing the room while opening the window;
• limiting the ingress of street dust during ventilation;
• reduction of heat losses.

However, a significant disadvantage of this method is that this measure will work properly only with properly functioning intra-house ventilation ducts.

If there are problems with the draft into the mine, they must be solved before the installation of window sill ventilation with an inlet valve. You may need to clean the ventilation.

To choose the optimal device for a particular room, it is worth focusing on the throughput of a particular system and the noise absorption coefficient. The usefulness of air exchange depends on the first parameter, the second affects the comfort of the inhabitants of the house. And the presence of soundproof membranes will significantly reduce the penetration of street noise into the apartment.

Window sills with holes for window ventilation

Address: st. Novocheremushkinskaya 57, between the metro stations Novocheremushkinskaya and Profsoyuznaya.

Problem: Window sills cover the radiator, therefore, poor air circulation around the windows, resulting in fogging of double-glazed windows.

Completed work: Holes were drilled in the window sills for ventilation. For aesthetic purposes, decorative mesh overlays are glued over the holes.

To eliminate window fogging, in this case, it was necessary to drill holes in the window sill for better air circulation. We used a regular screwdriver and a regular drill. In order to prevent drilling waste from flying around the room, we used a vacuum cleaner.

In functional terms, the work has been completed - warm air from the radiator will freely rise up parallel to the double-glazed windows, thereby draining the resulting condensate (appears due to the temperature difference between indoors and outdoors).

But, of course, we cannot leave window sills in this form. On top of the holes made, we glue a decorative lattice overlay, which copes well with the aesthetic part of the work.

As you can see, the holes in the window sill, covered with a decorative overlay, look quite organic. Window sills with ventilation will not only save the owners of the apartment from condensation, but also add a little zest to the interior of the windows.

Now let's add some colors and we're done. Of course, the flowers were arranged not by us, but by the owners of the apartment. It should be noted that the window sill has become much warmer and brighter.

The work has been completed. The cause of sweating has been eliminated. We hope for positive feedback and recommendations from the owners of the apartment.
