The limiter for opening plastic windows is a comb. Comb on a plastic window - do-it-yourself installation How to make a plastic window opening limiter

Plastic windows have long proved their practicality and functionality. One of their main advantages is the provision of tightness. However, this can also be considered a certain disadvantage, because the air in the room must be periodically updated. So you have to open the windows for ventilation. V winter period time is not very convenient, and at other times of the year too. To facilitate this task, the limiter for opening plastic windows is designed, which allows you to slightly open the hinged sash only at a certain angle. This will achieve normal level room ventilation.

Purpose of the limiter

You can define the device in question. Plastic window stop — this is a fitting element that allows you to install and fix the window sash in a certain open position. Structurally, this mechanism is a slotted bar, as well as a sash position lock. It allows you to change the position of the open window sash, usually within 1-10 cm. The slats that regulate the degree of opening of the sash are also called combs.

When such a device is installed on the window, the sash will not slam shut from a draft and will not swing open completely from a gust of wind.

Varieties of combs for windows

Comb for PVC windows may vary depending on the material of manufacture:

Limiters for windows also differ in the installation method: under the handle of the sash and in the overlap (end) of the sash.

Combs with fastening under the handle

Such a limiter for opening a plastic window consists of a comb and a pin (retainer), which is fixed under the window handle. The comb itself is mounted on a fixed frame. Depending on the design, the comb can be lowered or raised, taking up a minimum of space in the lowered position. This is the most convenient option. There are also combs that cannot be fully raised or lowered by pressing tightly against the frame. They are less convenient, as they constantly cling to the curtains, create obstacles near the window.

It is better to choose a metal retainer for windows, since plastic product can break very quickly. When choosing a retainer, make sure that its holes match the screw holes in the handle.

Combs with fastening in the overlap of the sash

The sash blocker of this type is not attached under the handle, but at the end of the sash. The comb itself is traditionally fixed on a fixed frame. The place of attachment of such a limiter does not depend on the location of the handle. This makes it possible to place it anywhere. For example, sometimes just opposite the handle there is some piece of fittings, so fixing the latch under the handle is impossible.

The pin is fastened with a long self-tapping screw, which must pass through both internal lintels of the sash overlap. Only in this case, the fastening will be sufficiently reliable.

Important: This opening lock for plastic windows cannot be installed on wooden sashes. The forces generated on the pin are such that they can damage the wood along its fibers.

Setting the limiter

You can install a window stopper at any time, including on plastic windows that have been in operation for a long time. The design of the limiter provides for this. Especially this simple mechanism what is the comb.

Tools needed for the job

In order for the protection against opening or closing plastic windows to be installed correctly, before installing the comb, it is necessary to prepare the following tools and materials for work:

limiter (comb) with a pin;
marking tool (pencil);
drill with drills;
screwdriver "Cross" or a screwdriver with an appropriate bit;
self-tapping screws up to 13 mm long. Longer self-tapping screws should not be used, as they can damage the window profile.

Tip: If a limiter is installed in the overlap of the window sash, then a self-tapping screw is additionally searched for, the length of which would exceed the size of the latch by 3 cm. Having passed through the latch, the self-tapping screw will firmly fix it on the end of the sash.

Mounting a limiter with a mount under the handle

Installation of a limiter with fastening in the overlap of the sash

The installation location of the limiter is preselected. Since the handle is not involved, the comb can be installed anywhere on the sash.
A comb is screwed to the frame. For this, self-tapping screws up to 13 mm long are used.
When the sash is closed, the position of the latch on the sash overlay is marked with a pencil. The latch should be located exactly opposite the comb, but at the same time so as not to interfere with the closing of the window.
A latch is screwed to the end of the sash (a hole is drilled under it beforehand).
The operation of the limiter is checked.

Cons of combs compared to valves

The regulator for opening plastic windows, in addition to undeniable advantages, is not without some disadvantages. They must be taken into account in the process of deciding on the installation of a restrictor, if there is a choice between them and inlet window valves:

This device is not a barrier for small children. It can be easily opened, after which access to the open window will be unlocked;
If the dwelling is located on the first floor, intruders can take advantage of the opportunity to enter through a half-open window. The comb is easily removed from the latch, and the window sash opens from the outside;
If you forget about the ajar window in the cold season, then there is a high probability of overcooling the room;
When attaching the sash to the latch, the soundproofing properties of the plastic window will not be ensured;

Compared to combs, window air inlets do not have these disadvantages. Fresh air enters in moderation, and the window itself remains closed.

If you decide to install a sash opening limiter on your window, then follow the recommendations listed above, consider all the nuances of the installation. In this case, the stopper will serve you properly long time and you won't be disappointed.

Plastic windows are particularly tight, but at the same time they allow you to ventilate the room without any problems. The main advantage is the adjustable level of ventilation, i.e. you can open the window wide open or slightly open from above. It can also save you from accidents, for example, if there are children / animals in the family, then they can fall out of a fully open window.

But, despite this, some prefer to install a special regulator for guaranteed safety. How to install a limiter on plastic windows and what might it be needed for? Why you need to put:

Good accident insurance. If there are children/animals in the room, then with full ventilation they may fall out of the window.
Maintains the integrity of the sash. When opening “to the full”, a strong wind can move the sash due to which it can hit neighboring objects, which can cause unwanted defects or complete breakage of the sash.
Minimizes damage to plants on the windowsill. Airing is not always beneficial for many colors, because. due to sudden gusts of cold / hot air, their condition may worsen. In this case, the plant gets a limited amount of air from external environment, which manages to change the temperature to the average for the room.
It is more difficult for birds to accidentally fly into an apartment. In case of mosquito net birds can break through it at high speed and end up indoors.
It is possible to adjust the opening width with a larger differential than without a limiter.

The limiter can be in the form of a comb (most often), as well as a chain or cable.

Installation - step by step process and instructions

To install the comb on plastic window You will need to purchase the following items:

Limiter (comb). There are several variations. On sale, there are more often models with the ability to open a window by 2-6 cm.
Drill with a 2-5 mm drill (in no case more).
Screwdriver. Any will do, but it is better to focus on the characteristics of the bolts installed on the handle mount. This can be found out by moving the plastic latch (you need to pry it with something thin and turn it).
Pencil or pen.
A few screws.
You may need a camera (you can use any available camera).

Initially, you need to remove the handle itself, under which a special bracket will be installed. Then it will need to be put in place, so you need to remember the location of all the elements in the desired sequence (for convenience, a camera is used). Withdrawal process:

The plastic latch rotates 180 degrees. To do this, you need to pry it off with a fingernail. After clicking, it turns freely. Installed in place with no problem.
Using a screwdriver, the bolts are unscrewed.
The structure is removed.

Then comes the brace. Installation is simple - you need to "try on" the bracket, and then install the handle on top of it. Installing the handle is similar to the removal process, but in reverse order.

Now you can put the comb, which will be the limiter. Be sure to “try on”, otherwise it will have to be reinstalled, and traces of fasteners may remain in the old place. Mark the place with a pencil or pen (it can be erased without problems after installation). Also mark the places where the screws will be inserted.

Then the scallop can be set aside and drilled with a drill shallow holes. Do not be afraid to damage the plastic, because. with proper marking, defects will be invisible. The limiter is put back in place and fixed. Then it is screwed with screws or self-tapping screws.

You can also do without a drill by screwing the self-tapping screw with your hands. However, you need to act carefully and try to fix them as best as possible. Otherwise, the scallop may fall off, and traces will remain in its place, and it will not be possible to install it again.

In addition, plumbing, heating, electrical, conventional cladding and balcony extensions. That is, repairs in an apartment or house were done on a turnkey basis with all the necessary types of work.

To begin with, a window opening limiter can imply not only various mechanisms, but also various functions - it all depends on what you are going to restrict and for what.

For example, you can block the full opening of the sash from children so that the child does not accidentally fall out of the window. And you can install shutoff valves, which provide a micro-ventilation mode.

Let's deal with this in more detail and learn about the types of child locks and devices for air exchange from the street.

Window restraints

Note. The very word "limiter" as a mechanism implies a forced reduction of any area of action. And each of them has its own instructions for installation and use.

Children's locks

I. Lock handle

Perhaps the most popular limiters for plastic windows are metal handles, which have built-in shut-off valves that open with a key. The advantage of such a constipation is that it does not differ in appearance and general configuration from a standard handle.

Therefore, to install it, it is enough just to swap the mechanisms in places. After replacement, you will be able to block the transom in two modes - closed or folding, from which it will be possible to exit only with the key.

II. Rim lock

It is quite easy to install such a limiter with your own hands: it is screwed onto the lower sash from the plowing side. Pay attention to the top photo - it is clearly seen that the working part of the lock is beveled, which makes it possible to open the transom in tilt mode without using a key.

But here you should be very careful when installing, so as not to protrude beyond the porch and not to support the rubber seal, as this will prevent a snug fit and the transom will not close.

III. Wrap-limiter

The restrictive wrapping is very similar in principle to the overhead lock, but it is fixed not on the sash, but under it to the lower profile of the frame - you see this in the photo above.

The essence of the functioning of the device here is quite simple - you turn the wrapper flag and lock the mechanism with a key. The restriction here is valid only for the swing mode - the folding opening can also be done in the closed position of the device.

IV. Mortise lock

In the upper image, you can see how the mortise installation of restrictive valves for plastic windows looks like. According to the principle of operation, the design is very similar to the invoice version and twist.

However, installation is much more difficult here - you will need a tool to mill the bottom profile. Therefore, for self-assembly such a mechanism is not always acceptable. Here, too, only the swing mode is locked - the tilt function is not limited.

V. Handle instead of a key

And now let's figure out how to put a handle with a plug, which functions in exactly the same way as the standard version, but is removed after being transferred to desired mode. For installation:

the native handle is removed;
in its place, a socket with a decorative cover is screwed, which moves up and down, opening and closing the adjustment hole.

In fact, this is the same key, only a few larger sizes.

VI. Chain stopper

A children's limiter with a cable is similar in design to a door chain, only most often a metal cable in isolation acts as a limiter here, but there is also a chain.

This variant of constipation does not provide for fixing the sash in any particular mode - they all function. Only with a swing opening, the transom can only move within the length of the cable, which is locked with a key. For a child, this protection is quite enough.

VII. Sliding window lock

Blockers for sliding systems look somewhat different. For example, it is much more convenient to make a plastic or aluminum window on or a loggia sliding rather than hinged - this saves usable space.

Of course, here you can adapt such a blocker, which we considered in the first paragraph, but still it is much more convenient to fix it on the side, as shown in the top photo. Several holes are drilled in the frame, and you can fix this constipation in any mode convenient for you and safe for the child.

For most blockers, self-tapping screws are used during their installation. When choosing screws, I advise you to limit yourself to a diameter of 3-3.5 mm and a length of up to 15 mm so that it does not rest against the steel profile inside the PVC.

3 ventilation modes

Handle for microclimate:

The handle of the right leaf is in the micro-ventilation mode, the left one is in the “closed” position

some manufacturers of plastic windows provide the function of small opening in tilt mode even during the manufacture of windows;
in fact, you are buying a product and you do not need to do anything to make the minimum air exchange - everything is done when arranging the shutoff valves;
such designs have four positions of the handle:

if the lever is turned vertically down, this means that the window is completely closed;
horizontal position at 90° indicates the possibility of swing opening;
tilted up by 45°, this is micro-ventilation;
vertical turning upwards allows the sash to be opened in tilt mode.

Comb blocker:

a blocker of this type allows you to limit the opening of the sash in several modes, that is, by the number of notches on the latch. In this case, there are four, but there may be more;
this lock consists of two parts - a comb strip, which is screwed to the frame at a distance of one millimeter from the sash and a counterpart, which is placed under the handle;
since it is very simple to install a limiter on plastic windows (meaning a comb), even a teenager can do it. To do this, one screwdriver and two screws are enough.

Climate valve:

the climate valve is not a lock in the mechanical sense of the term, however, it is a limiter that regulates the flow of air from the street;
since the installer fixes it inside the profile, then outside (from the side of the street and from the side of the room) only decorative overlays will be fixed, which do not spoil at all appearance window frame (they are selected by color);
it is noteworthy that the noise level during the operation of such a valve almost does not increase, in any case, you will not feel it, since there is no direct hole here, and the sounds are damped against the walls of the valve;
the humidity level is controlled by polyamide sensors due to their own expansion coefficient, i.e. the dampers do not need power supply.

Conclusion

In order to figure out how to properly install a particular limiter, you need to carefully read the instructions that are usually attached by the manufacturer.

In addition, the installation of some models is described on the site and there is also useful information in the video in this article. And if you have any suggestions, tell us about it on the forum or on this page in the comments.

passive ventilation occurs through them. Fully opening is a good method, but sometimes it is not possible, for example, during the winter season. There is only one way out of this situation - to install a comb on the plastic window.

Then the ventilation will be safe and effective. For these purposes, these devices were invented. It is very easy to install even for non-professionals.

The limiter - that's how it is correctly called, but is popularly called a comb.

Which allows the window to open at a given distance from 2 mm to 5 cm. This is quite enough to ventilate the room at any time of the year.

The device consists of: a latch and a bar equipped with teeth. Made from plastic material. Fixed on a stand with holes for mounting on the window frame.

The bar is equipped with a swivel, thanks to which it rises when it is needed, since it remains movable.

The bracket of the device in the form of a frame is the same size as the mounting plate under the handle. The bar with teeth and the bracket are made from the same material, usually plastic.

Although there are models made of metal. How to install a comb on a plastic window is described in detail in the instructions for the device.

Advantages and disadvantages

Simplicity of device and installation are the main and only advantages of the limiter. As for its disadvantages, they lie in the fact that several holes will have to be drilled on the window frame during installation. Is it dangerous for window design?

Judge for yourself: this is a kind of intervention in the design, which can lead to a decrease in the strength of the profile itself and deformation of the frame and the risk of leakage if miscalculations were made during the comb.

How to properly install a comb on a plastic window and not make a mistake will be described below.

The errors made can also lead to the fact that the properties of the system will be lowered, the sound insulation will be broken. Therefore, it must be installed very carefully and carefully.

Limiter installation step by step

To mount a comb on a plastic window with your own, you will need:

The limiter itself
Drill with a diameter of no more than 2mm
Electric drill
Screwdriver for driving screws
Marker for marking

Work order

The first step is to attach the latch to the frame under the handle
Attach the comb bar to the frame with self-cuts

Perform all actions slowly and deliberately in the literal sense of the word, because in case of an error, re-installation is impossible. The device is installed in two stages: a latch on the frame frame and a bracket on the sash handle

Installing the latch

We disassemble the sash handle. the plate (cover) is very carefully hooked with a knife. Remove the decorative plate very carefully, do not scratch it! Plastic is very easy to scratch. The functionality of the lid will not be affected, but the aesthetics and appearance will suffer.
Under this cover are the fixing screws from the handle, unscrew them and remove the handle
The pin with which the handle is equipped can open and close the window lock, check this
We combine the bracket and frame with the openings of the sash, installing it in place of the handle, they should ideally match
If everything is done correctly, insert the pin into the window hole
The bracket should, as it were, "sit down" on the pin
We install the handle in its original place, twist
The edge of the rod should stick out from the outside of the sash

Bracket installation

In this step, the correct definition of fasteners is the most important point so please adhere to the following guidelines:

We put a plate with teeth on the latch
We cover the window sash, fit the bracket to the frame frame
With a marker we make marks for fasteners, marking its location
Once again, we double-check whether the limiter hits the latch correctly
We twist the first self-tapping screw into any hole in the base of the comb
Align strictly vertically and screw the rest
Self-tapping screws should preferably be screwed in the first time

It is very important to tighten all the screws and screw them in correctly, so as not to redo them later. Otherwise, this will lead to the fact that the surface of the frame will crumble and holes will appear.

In order to learn this lesson better and faster, watch the video on how the comb is installed on the plastic window.

After everything is done, and all the parts are installed, test the operation of the limiter.

Lift it up, set the window opening to the desired distance, lower the comb, fix it: the rod should “sit down” without difficulty in one of the grooves. If so, then you did everything right. More details can be seen on the video:

Device and types of window restraints

The limiter is a small detail window fittings. When ordering a window, its installation can be ordered immediately, or you can purchase it separately and install it yourself. They put them not only on plastic, but also on aluminum and wooden window sashes.

In addition to window sashes, products can also be used for balcony doors.

Structurally, any internal limiter consists of 2 parts:

The part that is attached to the frame.

The part that is attached to the sash.

M eat these parts can connect 3 different ways, which we will discuss in more detail below.

Comb limiter

The most popular and cheapest option. H a multi-position bar with gaps is installed on the frame, a protruding latch is installed on the sash. A gap clings to it, and the bar rigidly fixes the sash, preventing it from moving in any direction.

For hinged windows it can be installed at any height of the sash, for tilt and turn-tilt windows it is mounted on the top. Almost all models the latch is attached under the window handle.

Planks can be of various lengths and have a different number of gaps.(recesses) . The longer the length, the greater the opening angle of the sash. The more gaps - the "thinner" it can be adjusted.Most often there are combs with 4 gaps and a bar length of 10-12 cm. Less often, there can be up to 10 gaps.

They are usually made of PVC, less often - of metal.

Since the length of the strip with gaps is small, the comb is used for micro-ventilation(as an alternative to a window leaf)- fully It won't let you open the door. barrier d For a curious child, such a detail will not work either, and even more so - it will not protect against penetration from the outside (for residents of the first floors).

P The approximate price of the simplest plastic comb is about 150-300 rubles.

Device, principle of operation, 3 ways to mount combs on a window (video)

Cable stopper

Such a latch consists of 2 small parts(one - is attached to the sash, the second - to the frame). Between themselves, they are connected by a cable (usually metal, inplastic braid), which does not allow the sash to open further than its length (usually up to 20 cm,that is, it will not work to open the window strongly). In some models, a chain is used instead of a cable.

For pivot windows, the latch can be installed at any height of the sash, for tilt and turn-and-tilt windows it is mounted on the top.

A cable window stopper is more reliable than a plastic comb, it is much more difficult to damage it (tensile strength for high-quality products can reach 550 kg). The major downside is that it does not fix the sash at the required distance from the frame(that is, a gust of wind can slam the window), but simply does not allow it to open too much.

Therefore, this option is more suitable as protection from children or penetration from the outside. If the limiter needs to be chosen specifically for ventilation, then it is better to use a comb.

The price of such accessories is about 800 rubles (manufacturer Penkid).

Lever limiter

More complex and expensive option.It is usually installed under the sash (on the underside) of pivot windows.Allows you to open the sash from 0º to about 90º . The maximum angle is set when mounting the limiter.Some models - allow you to fix the sash in the selected position, the other part - simply does not allow it to open further.

T Which latch has the form of a metal (aluminum) strip that connects 2 parts - axle and holder (one on the sash and one on the frame).It is the bar that keeps the sash from opening more than the set angle.

This type of limiternot striking, and allows you to set a wider opening level(than a comb or cable).It is useful in cases where it is impossible to open the sash completely for some reason (for example, so that it does not hit the slope, or if something is standing on the windowsill).

Of the minuses of this design - it is more difficult to adjust the opening angle than that of a comb.

The price of such a product is about 2000-3000 rubles.(specific models - Winkhaus FB, Winkhaus DB).

Purpose of window restraints

O all types of borders serve the same purpose:prevent the sash from opening beyond a certain angle. Part of the model to her - may fix the window sash in the desired position.

This may be required for the following reasons:

so that the sash does not slam shut from the wind;

so that the sash does not open abruptly (on the windowsilloften put something, for example - pots with plants, and the sash opened from a gust of wind can push );

so that the cat does not jump out (even when opening the hinged window in its upper part, the gap is wide enough, and the animal can climb through);

to provide ventilation in winter (both for breathing and to prevent condensation);

so that the child cannot open the window on his own (for this purpose it is better to use more reliable device- children's lock).

Pros and cons of application

To the benefits of using window locks include:

cheapness;

ease of installation;

the ability to apply on any type of windows (any material, any method of opening, any frame size);

the possibility of fixing the sash in the desired position and limiting further opening.

M such accessories do not have sinuses - it is extremely simple, does not require maintenance, is useful,it can be easily installedeven with your own hands.

Mounting tools

To put the latch on the window, we need:

The fixer itself.

Drill and drills of small diameter (up to 13 mm).

Self-tapping screws.

Crosshead screwdriver.

Marking tool (pencil, marker).

How to install an opening limiter on plastic windows?

Now about how to set the limiter correctly, step by step:

We attach to the sash the part to which the latch will cling (plastic or metal - it doesn’t matter). Some devices are attached under the handle - so it will have to be removed. Some are attached directly to the sash.

If the handle was removed, after installing the latch, we return it to its place.

The retainer is going ( if comb - put on the fixed part, if the cable - c clings).

The sash opens and closes several times - in order to " try on" and accurately determine the place of attachment of the second part of the limiter (on the frame). The chosen place is marked.

A hole is drilled in the selected location in the frame.

The second part of the limiter is attached to the frame with self-tapping screws.
