Given the characteristics of glass as a material with a certain rigidity, spatial structures like double-glazed windows are distinguished by certain size restrictions. They can be within a minimum of 300mm on one side and in an aspect ratio of 5:1. But the maximum glazing area should not exceed 3 m2 in a single-chamber package with 4 mm thick glass and 4.2 m2 with 5 mm glass thickness.

What you need to know when choosing a double-glazed window Double-glazed window is 70% of the entire window. In a PVC double-glazed window, the glasses are rigidly fixed, there is a special spacer between them so that the windows are strictly parallel to each other. Sometimes a moisture-absorbing material, silica gel, is placed inside.

Disadvantages and the issue of environmental friendliness The frames of plastic windows have one significant drawback - non-repairability. Scratches, scuffs and other surface damage cannot be repaired on plastic. However, plastic is much harder than wood, and it is more difficult to scratch it during operation.

Plastic can hardly be called an environmentally friendly material, but modern manufacturers have tried to make it as safe as possible for humans. In its manufacture today, components that are harmful to health are not used.

Profile PVC profile is a frame, that is, the basis of a window structure, and therefore it must: have a high ability to retain heat: the minimum number of chambers acceptable for the climate of Ukraine is three (for example, "Bluevolution"). This option is ideal for glazing of balconies, private houses, including in the northern regions of the country, as well as residential and office premises in the southern part of Ukraine; differ in structural rigidity: a reinforced profile has excellent indicators of this criterion (metal frame thickness - at least 1.5 mm); comply with environmental standards: for high-quality PVC profiles, safe raw materials are used that guarantee stable technical characteristics, do not emit toxins when the temperature changes, have a stylish design: a profile with a uniform surface is a good base for an ideal window, and the trend is white PVC Salamander, not loses its glossy appearance even after decades.

Order a free call Selecting the type of sash opening When choosing plastic windows, you should decide on the type of sashes. They determine the functionality of the design and comfort during its operation. The type of sashes must be selected depending on the size of the structure, how many windows are in the room and whether there is a need for regular ventilation.

Intra-profile ventilation of PVC windows The method of ventilation of a room with closed sashes can be implemented in different ways. Some manufacturers install a slotted, folded or overhead ventilation valve in the PVC profile.

Slotted air ducts are a channel with a damper that opens manually or automatically. Seam valves have a more complex device with a damper that shuts off the flow at a dangerous level of draft. Overhead mechanisms are able to provide the maximum influx of fresh air, however, they significantly reduce the sound and heat-shielding properties of the window block, therefore they are not widely used.
