It has the functions of energy saving, watertightness, sound insulation of more than 29 decibels, waterproof and so on, all of which are up to A1 window standard, reducing heat loss by half compared with ordinary doors and windows, soundproof, and adopts heat insulation broken bridge aluminum profile and hollow glass; less than ㎡ · K, good air tightness, dust prevention, noise protection, reduce heating costs by about 30%. The Broken Bridge aluminum doors and windows K value of heat-conduction coefficient is 3W/Broken Bridge aluminum doors and windows.
Bridge-cutoff aluminum alloy doors and windows has good tensile and deformation resistance, and is not subject to acid and alkali corrosion. After installation, it does not need to be maintained at all. The performance is very good, and its life span is generally as long as 50 years! And it is also a kind of green and environmentally friendly building materials, which does not produce harmful substances during production, and all materials can be recycled and reused.
The sound insulation effect of broken bridge aluminum doors and windows is strong. Its structure is carefully designed, and the joints are very tight. Even if it is installed on the house next to the highway, residents will not be disturbed by noise. The sound insulation of the air reaches 30-40db.
Broken Bridge aluminum doors and windows, using heat insulation broken bridge aluminum profile and hollow glass, with energy saving, sound insulation, noise protection, dustproof, waterproof and other functions. The Broken Bridge aluminum doors and windows K value of heat-conduction coefficient is below 3W/㎡ · K, which reduces the heat loss by half compared with ordinary doors and windows, reduces the heating cost by about 30%, has a sound insulation of more than 29 decibels, and has good water tightness and air tightness, they all meet the national A1 window standards.
