Plastic windows are firmly entered into our lives. They have a number of positive qualities, like a high level of noise insulation, ease of operation, excellent appearance, excellent protection against exposure to the external environment. Yes, and the cost of plastic windows every day is becoming lower. However, during operation, small disadvantages and inconvenience of the initial configuration of the window were observed. Fortunately, they are easy to fix by acquiring and installing additional accessories. One of them is the window lock.

Window lock. What is it needed for what

The easiest retainer for the window is a bar equipped with teeth. This model is called "comb". "Comb" allows you to fix the plastic window in an open or inclined position with a certain size of the gap. The width of the gap is selected from 1 to 7 cm.

The need for equipment of the plastic window The record is due to the following functions:

1. Providing protection from slamming. An open plastic window under the influence of draft or strong wind often slams. Of course, the double-glazed glass in plastic windows is distinguished by significant strength, so that the glass in cotton is unlikely to break. However, cotton is unpleasant by themselves. Yes, and the window will most likely remain in the closed state. This causes inconvenience. After all, it was planned that it would be open. But when using the retainer of the plastic window, the sash will remain in the position in which it is fixed.
2. Providing protection against swinging. Another effect of a draft, which is directly opposite to slam. A shut-off to ventilate the sash swallowing the lamb, despicable everything in its path - pots with flowers, documents, other things from the window sill.
3. The possibility of ventilating during the cold season. Thanks to the fixer, it is possible to switch the sash to the fixed width. In this case, the width of the slit between the sash and the frame can be very insignificant, 1-2 cm. This is sufficient for airing. But the temperature balance of the room does not break, the combination does not threaten him.
4. More full-fledged ventilation. All plastic windows have a ventilation mechanism involves the tilt of the top of the window. It is not very convenient and productive. The room is better ventilated and gets more fresh air when opening the entire sash. The use of the retainer in the extreme position allows you to lock the sash at a distance of about 7 cm from the frame. This is quite enough for the full air ventilation even in the hot season.
5. Security for pets. For most buyers, this aspect is very important. The fact is that the plastic window open to ventilating was the cause of the death of not one pet. As mentioned earlier, the ventilation in the standard configuration of the plastic window involves the slope of its upper part. Trying to jump out of the apartment through a dialing window, the cats are stuck between the sash and the frame. The slot is narrowed to the bottom and does not allow to squeeze. And it is impossible to boil up the plastic window, slide claws. The presence of the window opening lock allows you to avoid tragedy. Lock the sash at maximum distance from the frame, and the favorite will get a safe way out at any time of the day. Of course, if you live on the first floor. If the apartment is located high and it is necessary to prevent the fall of the animal, lock the sash at a distance of 4-5 cm from the frame. This is enough for full ventilation. However, it is clearly not enough to get out of the apartment and fall down.
