Broken bridge aluminum three glass is good or double hollow glass good
The use of three glasses is an effective way to save energy and energy. General glass doors and windows are the building's cold (heat) the largest loss point, and three layers of insulating glass heat transfer coefficient of 1.63 ~ 3.1w / mk, is the general glass 29% to 56%, so the heat loss can be reduced by about 70 % Or so, greatly reducing the heating (cold) air conditioning load. Obviously the larger the area of the window, the insulating effect of the three layers of insulating glass is more obvious. When the direct sunlight, the general glass and three-tier glass energy-saving effect is significantly different. 100% of the solar energy through the 5mm heat reflective glass when a total of 83.9% of the energy through; and 5mm heat reflective glass and 4mm float glass made of 20mm insulating glass, 100% of the solar energy can only penetrate 17.8%. It can be seen that the energy saving effect of the three-layer glass is very significant. Experiments show that the use of three glass made of high quality doors and windows, can effectively make the indoor and outdoor temperature difference of 12 degrees or more.
If the configuration of three layers of insulating glass, of course, better than double glass, three glass can effectively block the conduction of low temperature, in Switzerland and the Nordic countries, due to cold weather, the general use of three layers of insulating glass, and some places also use four Layer of insulating glass.
Broken bridge aluminum doors and windows are basically equipped with double-layer insulating glass, there are a small part of the configuration of three layers of insulating glass, in the northeast are basically three layers of insulating glass. The following are the same as the "
Three layers of insulating glass refers to the three glass together in the insulating glass, than the double glass a layer of glass and aluminum, the advantage is three layers of red insulating glass insulation good seal better than the two layers of insulating glass safety factor to High, sound insulation, thermal conductivity is better, in terms of sound insulation, double-layer insulating glass and three-tier glass is almost double layer slightly better than three layers of glass noise.
