Which is better for KFC and steel doors?
The KFC door has the following advantages over the steel-wood door window:
1, water resistance, corrosion, flame retardant
It can be used in industrial buildings where it is rainy, hot and corrosive.
2, good insulation
Although the thermal conductivity of PVC is close to that of wood, because the window frame is made of hollow profiled materials, coupled with reliable caulking material, its thermal insulation is much better than steel, aluminum and wood windows.
3, air tightness and water tightness
The design and installation of PVC windows take into consideration the airtightness and watertightness requirements. Under the price adjustment of 300N/m2 indoor and outdoor pressure, no water is introduced for 10min, and when the wind speed is 40km/h, the test is marked with ASTM-283, air leakage. The amount is only 0.00283m3/min.
4, good sound insulation
According to DIN 4109 test, the sound insulation is up to 30dB, while the sound insulation of ordinary doors is only 25dB.
5, good decorative effect
The appearance is flat and beautiful, the color is bright, and it does not fade for a long time.
6, good aging resistance
It is blended and extruded with a resin such as PVC and polyacrylic acid grease (PAE), and the outside is a colored PAE resin layer. The interior is a white PVC layer with many color variations, which not only improves the decorative effect, but also has a reliable guarantee for aging resistance.
7, can be repaired
Because the installation of the glass is inlaid with a rubber sealing strip, no putty putty is needed, and it is not necessary to consider the aging cracking problem of the putty.
