Type of Glass Unit
There are several main types of glass units:
- Single-chamber. The simplest type of glazing, which is usually used in climates with mild winters. Freezing occurs at a temperature of 10-15 degrees below zero. The level of noise isolation in such models is lower than in others. Because of this, they should be installed only if the windows overlook a calm courtyard.
- Two-chamber. Suitable for private houses and city apartments. Keeps warm well and reduces external noise. However, when it faces busy streets, the air gap should be facing inward.
- Three-chambered. The warmest windows do not lose their properties even in cold winters down to -30 degrees. However, the thickness of the glass slightly reduces the ability to transmit light. Also, this feature leads to the need to install a large frame. The mass of the structure with three chambers is greater than the previous options, which is why there is a large load on the fittings.
