When a person chooses a window, he must remember that the operation of a double-glazed window largely depends on the fittings. Particular attention should be paid to window hinges. If you choose them correctly, then the apartment will be protected not only from cold and drafts, but also from dust. The noise level that comes from the street will decrease.
What are the types of loops?
Plastic and any other window should be easy to open and close. The hinges must also provide a secure fit. These fittings can be divided according to the type of location into upper and lower.
Also, hinges are classified according to the type of window:
- Rotary. It will depend on them where the window will open - to the street or inside.
- Flip-up. Contribute to the opening of the window up.
- Screw-in window hinges. High strength.
- Invoices. They are a special kind of window hinges. They are bought for structures that are heavy. This type has a high price, but they are used quite rarely.
Window hinges for windows come in standard sizes as well as small sizes. Large mechanisms are rarely used. Also, these elements differ in the method of production. Pressed and forged specimens are produced. Some choose adjustable window hinges. Others take a simpler option - unregulated.
Which materials are suitable for production?
A big role in the manufacture of fittings for windows is the material from which the hinges are made. They must support the weight of the entire structure and prevent the sash from sagging.
Hinges are mostly made of brass. Aluminum alloy or steel is suitable for production. Some manufacturers work with especially durable plastic. Decorative strips are also made from it. To prevent rust from showing up on steel fittings over time, the products must be coated with a special galvanizing layer.
What to look for before buying?
Before you buy hinges, you need to determine the weight of the wings. Standard designs weigh 180 kilograms. Loops should be distinguished by increased strength. Each should work without failure for about 16 thousand cycles. You should take into account the weight of the entire double-glazed window, as well as how much the set of fittings weighs. Some use door hinges instead of window hinges.
It is believed that elements made by cold forging are extremely durable and last for many years.
How are hidden mechanisms different?
Nowadays, most people prefer to install in their homeshidden loops. This type has advantages over the classic one.
Part of the hinge is built into the sash, so it is not visible from the outside. This design looks very aesthetically pleasing. Plus, invisible hinges keep the room warm. The rubber seal installed in the window remains intact. The hinges keep cold and drafts out of the street.
This hinge mechanism has proven itself due to its high tightness. An additional window sash clamp appears. The lower part of the loop features a protective mechanism. It will reliably protect in case of hacking. This setup is great for residents of apartment buildings whose housing is located on the ground floor.
Feature of screw mechanisms
They differ in their composition. This includes the frame part and the folding part. Each element has threaded pins. Most often, this type of hinge is installed on wooden windows. The hinged part of the hinge is mounted in the window sash. A frame part is installed in the window box.
The use of this type of hinge increases the reliability of the structure and its service life. You can buy decorative caps for fittings. The design will be aesthetically pleasing and have a finished look.
This type is used when they want to be able to adjust the pressure of the valves. Each loop is equipped with several pins. There can be a maximum of 4 pieces. They are suitable for reinforcing windows that are large.
What care is needed?
To devicehinges worked properly, they need to be lubricated periodically. Some mistakenly believe that you can lubricate the mechanism with sunflower oil or petroleum jelly. Resorting to folk methods, you can ruin the loop device. You need to buy technical or synthetic oil. Mineral motor oil is well suited for these purposes.
You need to lubricate all parts of the window that are subjected to friction when opened. Metal surfaces must first be cleaned.
Many people wonder how often window hinges should be lubricated. It is recommended to carry out prophylaxis once a year. There are also special sprays for window hinges. They are convenient to use. Sprays allow you to evenly distribute the oil inside the loop. With regular care, this design will last a very long time. In addition, the window will open easily and silently.
