A double-glazed window is a system consisting of two or more glasses connected hermetically and significantly increasing the sound and heat insulation characteristics of a window. Glass is separated by a gap, which is filled with an inert gas (most often an agronomist) or air. Tightness is created using two seals: one in the gap between the frame and the glass, the other is poured outside.
Most double-glazed windows are single-chamber and two-chamber. In single chamber there are two glasses and one gap (chamber) between them. In two-chamber, respectively, three glasses and two cameras. The window area is basically the area of the double-glazed window, so it is very important to correctly determine its choice. The appearance, security, heat loss, and comfort of the room largely depend on the quality and characteristics of the chosen one. If you decide to put double-glazed windows, it is important for you to know what types of them are issued by the companies.
In winter, it is very important to reduce heat loss. Energy-saving characteristics can be enhanced by filling the inter-glass gap with inert gas and by spraying one of the inner sides of the glass (the so-called energy-saving or K-glass). These measures will help significantly reduce heating costs in winter and reduce heating in the summer. Such systems are called "energy-efficient double-glazed windows." Owner reviews allow us to talk about the energy efficiency of this product.
A single-chamber double-glazed window with energy-saving glass filled with argon is similar in its thermal insulation characteristics to a conventional double-chamber glass , but has lower sound insulation. But it weighs a third less and costs less, which is important, for example, when glazing balconies. So this option is best if you need balcony double-glazed windows with high thermal insulation.
There are shockproof glass that can be installed in display cases or on the windows of lower floors. You will not find external differences, but if you try to crack it or if it hits the ball, this glass will be unharmed. If impact-resistant glass can still be destroyed, then it will break into small fragments without sharp edges. Such glasses are appropriate to install in children's or other rooms with high safety requirements. Window systems with their use are also called "shockproof double-glazed windows." Customer reviews confirm the effectiveness of glass protection against most power influences. Such double-glazed windows withstand ten times the ball or hit a small stone.
Laminated glass is obtained by gluing several ordinary ones using a special film. They have enhanced soundproofing characteristics and are bulletproof. Systems that use laminated canvases are called "bulletproof windows." Expert reviews guarantee that such systems will withstand pistol bullets fired from a distance of several meters.
Quite often you can find tinted or sun glasses in double-glazed windows. Toning protects from sunlight, making the light softer. Sun glasses cut off up to 90% of ultraviolet rays.
In addition to the choice of glasses, tightness is very important. It is with the help of properly installed sealants and dehumidifiers that the possibility of water vapor getting inside the double-glazed window is eliminated, preventing the appearance of condensate in the winter (weeping windows). The double-glazed window should not fog up in any case. If such a defect is discovered before the warranty expires, the manufacturer must exchange the crying (defective) for high-quality double-glazed windows. Customer reviews suggest that a quality window product lasts up to 15 years, and does not “cry” even in severe frosts.
From all of the above it follows that, first of all, you need to decide on the characteristics that will become decisive when choosing double-glazed windows.
