Plastic windows are now considered the most popular and affordable. They have good operational characteristics, an attractive appearance, and a long service life. However, not all of the offered metal-plastic windows are of high quality. There are unscrupulous manufacturers on the market who skimp on components.
Manufacturer
If the company is reliable and has a good reputation, then they will most likely sell you good products here, as well as provide a long-term warranty, as here. Before contacting this or that company, you should first gather as much information about it as possible. For this you need:
- ask friends;
- read the forums;
- familiarize yourself with the contract for the provision of services and warranty obligations - such information is usually contained on the manufacturer's website;
- find out which components the company uses.
The legal component is also important. If the company has been registered for a long time, or does not work in the legal field at all, then it is better not to contact it at all, even at low prices. Also, do not hesitate to ask the manufacturer for quality certificates.
Type of profile and quantity of double-glazed units
Today there is a large number of metal-plastic profiles. A distinctive feature of quality production is compliance with DSTU. Profiles differ in cross-section, color, number of cameras. Each of the chambers performs its function - air flow, installation of accessories, etc. A high-quality profile system assumes at least 3 chambers with a wall thickness of at least 2 millimeters.
The double-glazed unit is the main element of a metal-plastic window. Sound insulation and heat insulation properties depend on it. 2-chamber double-glazed windows are considered the optimal solution for most rooms, they retain heat quite well and reduce the noise level in the room.
To improve thermal insulation, it is recommended to install multi-chamber double-glazed windows, or double-glazed windows. They are called energy-saving, have a special coating that does not transmit infrared radiation. Thus, the room is cool in the summer, and warmer in the winter.
Triplex-type double-glazed windows are installed on the lower floors next to the road. They are more difficult to disassemble, and their level of sound insulation is higher.
Special attention should be paid to accessories. It must provide for all needs, for example, micro-ventilation, "child lock", etc. It is not worth saving on accessories, as this is one of the consumables.
