The reinforcing element of the window is a U-shaped or square profile, which is inserted into the largest chamber located in the center. The thickness of the sheet metal from which the profile is formed is in the range of 1.5 - 2 mm. It is made of galvanized steel and is highly resistant to corrosion. An amplifier is installed in almost all structures, although according to the standards, with a frame length of less than 0.8 m, it can not be used.
Those. the window manufacturer must have a window conformity certificate, the profile manufacturer must have a certificate of compliance with the requirements of GOST 30673-2013 for the profile, etc.
The stability of geometric shapes, the preservation of angles, the overall strength of the structure largely depends on the thickness of the partitions inside the frame. It is difficult to check the jumpers, one can only hope for the veracity of the information indicated in the product passport. This is another fact in favor of choosing windows from large manufacturers - the process is well established there and no one will falsify products, risking damaging their reputation and incurring millions in losses.
What is the best PVC profile to choose Profiles are divided into three classes: premium, standard and economy. Which windows to choose will depend on the requirements for thermal insulation and the financial capabilities of the customer.
All profiles in exprof windows are equipped with reinforcing inserts with a thickness of 1.5 to 2 mm and have a protective zinc coating. Double-glazed window The main characteristics of the element: the thickness of the double-glazed window, the number of glasses and, accordingly, the chambers between the glasses, the presence of special glasses with heat-shielding coating.
Poor-quality elements can also provoke other problems with the operation of a double-glazed window. Sealant Sealant is responsible for a snug fit of the sash of the window structure and noise insulation, the absence of drafts. To choose a sealant for plastic windows, it is enough to know that high-quality sealing rubber or silicone is elastic, pliable, and odorless. To check the quality, you can compress the media and then release it. A good seal is easily pressed through and quickly returns to its original shape, there are no creases on it.
Even on dirty seals, it is not recommended to use organic or synthetic solvents. It is better to wash with warm water with neutral household detergents, dry well and lubricate. Of course, silicone oil and glycerin are not a panacea, but they can extend the life of seals by several years.
More than 5 cameras can be found in quality products of well-known brands, but already 7 cameras are a clear overkill. Studies have shown that with a noticeable increase in weight, thermal conductivity begins to increase - it is not the volume of the air gap that comes first, but the thermal properties of the wall partitions, which conduct heat better than air.
Rubber In terms of performance, rubber seals are not inferior to silicone and ethylpropylene, but at a much more affordable price. True, soft rubber is not very durable and eventually cracks from frost and heat, losing tightness. But it is just as easy to replace as the TPE seals, so there will be no problems with it.
In addition to energy efficiency, good sound insulation and comfortable lighting are important in the house. Plastic windows must be equipped with protective elements to prevent burglary attempts from the outside.
