Classes of the profile of plastic windows and their characteristics

The main material for the sash and frame construction is called a profile.

Vertical and horizontal elements are most often made of metal (aluminum, steel) and polyvinyl chloride.

PVC windows must be produced according to the standards: EN12608SR (Europe) and GOST 30673-99 (Russia).

Depending on the thickness of the profile walls, there are:

Class A

The thickness of the outer wall is from 2.8 mm, the inner from 2.5. This class is characterized by high thermal insulation.

Class B

5 mm, inner from 2 mm. Thermal insulation is significantly reduced, resistance to mechanical stress by 15%.

Class C

These are windows with a lower profile wall thickness than for classes A and B. It is recommended to install them in industrial premises where heat preservation is unimportant. They are even made monolithic, without opening mechanisms.

Reinforcement of the profile is performed by metal strips located inside. Hence the name metal-plastic windows.

The PVC material itself is distinguished by good resistance to atmospheric conditions, low heat transfer, environmental friendliness, excellent adhesion to paints and varnishes, durability, high sound insulation and low cost. Its aesthetics are also worth noting.

How to choose a high-quality profile

First, it is worth evaluating the appearance of PVC material.

It should be of uniform color, smooth surface and made of a monolithic canvas. The presence of spots, inclusions in the PVC structure should alert.

The most common profile width is 58 mm. Profiles 60 or 70 cm wide are usually installed in tall buildings or in harsh climates. Width 90 cm belongs to the premium class.

The thickness should be the same throughout the structure and be in the range from 2.5 to 3 mm.

A minimum of three air chambers are required for sufficient thermal insulation. That is how much fits into a 58mm wide profile.

Number of double-glazed windows

Best Profiles of Which Manufacturers Deserve Attention - Review + Video Do not forget about the number of double-glazed windows.

A glass unit is called several sheets of glass, fastened with a sealant and enclosed in a special frame.

The number of double-glazed windows makes the construction of the window heavier, therefore, for rooms with large openings, it is proposed to use single-chamber double-glazed windows.

And for a private house it is better to choose a two-chamber package of three sheets of glass, then the thermal insulation will be sufficient. Three-chamber packages are justified only in very cold areas

Attention! There should be at least two seals in the frame. Otherwise, condensation will form under the frame, which will lower the insulation and promote the development of mold and mildew.

Absolutely disgusting products a company with a well-known name cannot afford. Most likely, these will be one-day firms.

Therefore, give preference to products from manufacturers who have experience and have collected a list of positive reviews. In addition, the risk of stumbling upon a substandard product by choosing the windows of a large factory is much less. Small firms are unlikely to buy expensive productive and technological equipment.
