Requirements for the construction of windows
In order for the windows to be of high quality, you need to pay attention to the following parameters:
1. Construction. This is the frame itself (the basis of the entire structure), sash and glass, as well as fittings and insulation. The plastic window has a special structure, which provides an excellent level of heat saving and sound insulation.
2. Profile air chambers. The most popular are 5-chamber profiles, although there are 2 and even 8-chamber ones.
3. Double-glazed windows. This is the distance between the glasses. The glass can be 2-4, this parameter is selected based on the characteristics of the location of the house.
Glass type
Before buying a window, you need to pay attention to the type of glass:
1. Float glass. It is considered the most transparent.
2. Triplex. It is durable and burglar resistant.
3. Selective glass is only used for the inner layer.
4. Reinforced glass is safe and fire-resistant due to mesh reinforcement.
5. Tempered glass undergoes chemical and heat treatment (even when broken, small safe fragments are obtained).
Sealant
The cheapest, but at the same time, effective seal is rubber, it perfectly tolerates temperature drops from -40 to +150 degrees. EPDM is an inexpensive material that performs well.
Most often, thermoplastic elastomer is chosen as a seal - it combines the qualities of the previous two heaters.
Ventilation
It can be a familiar window, micro-slot ventilation. Combs are often used - special regulators for fixing the position. Sometimes ventilation valves are added to the windows (this is very convenient and effective).
Opening mechanism
The generally accepted mechanism for windows is a pivot. There are also folding, swing-out and sliding. The latter option is suitable when there is no place to fold the sash or open it.
Fittings
It should be of the highest quality. Particular attention should be paid to handles, which often become loose. The handles are removable or with a lock - these options are especially relevant in a home with children. There are also standard and anti-burglary handles (the window is blocked by external influences).
Profile
To give the greatest strength, the plastic profile is reinforced with galvanized steel with a thickness of at least 1.4 mm. Good plastic always has a uniform surface, there are no foreign inclusions and odors in it. It is better if the plastic is glossy, it will make it easier to care for the window.
If you choose a high-quality profile, then the window will easily last 50-60 years. The best profile - category A. The thickness of its outer walls - from 2.8 mm, internal - from 2.5 mm. Such windows are usually installed in residential buildings.
