Insulation energy and energy saving:
UPVC Windows & Doors are multi -cavity structures, which have good thermal insulation performance. Its heat transfer performance is very small. It is only 1/357 of steel and 1/250 aluminum. Modern buildings of air -conditioning equipment are more applicable.
The physical properties of UPVC Windows & Doors mainly refer to the air permeability (gas tight) UPVC Windows & Doors, the leakage (water tightness), wind and pressure, and temperature insulation performance. Because UPVC Windows & Doors have a unique multi -chamber structure, and the melting process is made into doors and windows, all gaps are equipped with doors and windows sealing strips and hair strips when installation of UPVC Windows & Doors, so they have good physical properties.
UPVC Windows & Doors are special formulas, and ultraviolet absorbers and low temperature shocks are added to the raw materials, thereby improving the weathering of UPVC Windows & Doors. Long -term use in the environment of temperature and climate. Between one 30 degrees and 70 degrees, the phenomenon of discoloration, deterioration, aging, and crispy in the change of scorching sun, heavy rain, dryness, and humidity. Plastic steel windows have been examples of 30 years in Western Europe, and their materials are intact.
UPVC Windows & Doors are not spontaneous, non -combustion, self -extinguished by fire, safe and reliable, and meet the fire prevention requirements. This performance has expanded the scope of the use of UPVC Windows & Doors.
UPVC Windows & Doors use excellent electrical insulators with different types of different profiles.
The main lies in the sound insulation effect of about 80%of the glass. Some sound insulation UPVC Windows & Doors on the market cooperate with the co -in cooperation with the resonance transmission of sound waves and use different glass combination structures, such as hollow glass plastic steel windows, ordinary double -layer glass. Enhanced doors and windows sound insulation effects. In terms of doors and windows, the use of high -quality rubber strips and plastic sealing accessories makes the performance effect of UPVC Windows & Doors significantly.
