Extended data:
Plastic doors and windows are multi-cavity structures with good thermal insulation performance and small thermal conductivity, only l/357 of steel and 1/250 of aluminum. It can be seen that plastic doors and windows have significant thermal insulation effect, especially for modern buildings with heating and air conditioning equipment. The relevant departments have investigated and compared this.
The main stress structure of aluminum-clad wooden window is thermal insulation and broken bridge. The wood used for the aluminum-clad wooden window is Korean pine growing near the Arctic region and larch in the primeval forest of Northeast Asia, and then it is strictly screened, preserved, degreased and flame retardant.
The use of German high-strength viscose ensures the strength, corrosion resistance, weather resistance and other aspects of wood, which is durable. That is, the indoor temperature of plastic steel doors and windows in winter can be 4-5 degrees higher than that of wooden doors and windows; It is best to use double glass in the north.
