Double -glazed window – these are two or three glasses united by one frame, between which there is a free space. The role of the frame, as a rule, is performed by an aluminum profile, the width of which determines the distance between the glasses. It is 6 or 10 mm. These are the most common values. A special material is added to the cavity formed by the glasses that remains the moisture remaining during the production of the double -glazed window.
In the production of a double -glazed window, the complete tightness of the space between the glasses is achieved. This gives the advantage that neither dust nor other pollution falls on the inner surface, thereby excluding the need to wash.
Types of double -glazed windows
Double -glazed windows are sold and produced mainly by single -chamber and two -chamber. Sing -chamber double -glazed window consists of two glasses. Two glasses form one chamber between them. Seeing the designation of the double-glazed window 4-16-4, know that you have a single-chamber double-glazed window formed by two glasses, whose thickness is 4 mm, and the distance between them is 16 mm. Two -chamber double -glazed windows are made of three glasses. They are indicated by five numbers, the extreme and the middle between which are the thickness of the glass used, and the second and fourth number is the distance between the glasses in millimeters.
The thickness of the glasses, the distance between them is determined by the noise -insulating and heat -insulating properties of the package. Of course, the thicker the glass, the stronger the insulation. In the usual single -chamber double -glazed window, already at -8 ° C from the difference in the outer temperature and temperature inside the room, condensate forms. In two -chamber, this indicator is slightly lower and is -18 ° C.
Of course, the thicker the glass used in the double -glazed window, the more it will absorb extraneous sounds from the street and resist the loss of heat. But modern energy -saving technologies do not stand still. You can achieve minimum losses of thermal energy by applying India and tin to the surface of the connection of the connection, which significantly increase the thermal insulation properties of the double -glazed window, while do not affect the transparency of the glass. Energy-saving properties in a treated surface are more than 7-10 times compared to ordinary glass. In addition, in extreme conditions of the Far North, double -glazed windows are used, in the cavity of which the gas arg is pumped. It allows you to maintain its properties even at extremely low temperatures -up to -112 ° C.
