1. China air tight door manufacturers have good thermal insulation: the thermal conductivity of aluminum-plastic composite cross-section plastic is 1250 times that of aluminum, and it has good air tightness. In cold areas, although there are dozens of indoor and outdoor areas below zero, it is another A world.
2. China air tight door manufacturers have good sound insulation: its structural design, tight seams, test results, sound insulation of more than 30dB, in line with relevant standards.
3. The influence of china air tight door manufacturers: the aluminum alloy profile on the outer surface of the aluminum-plastic composite material and the plastic steel window have a stronger influence than the electrical resistance.
4. The air tightness of china air tight door manufacturers is good: aluminum-plastic composite windows are sealed with multiple strips or tapes in each slot, and the air tightness is hierarchical, which can give full play to the air-conditioning effect and save energy by 50%.

5. Door and window design with good water tightness: waterproof structure, rainwater will be completely isolated from the outside, and the water tightness meets the relevant national standards.
6. The fire protection of china air tight door manufacturers is good: the material is UPVC plastic steel doors and windows, which do not spontaneously combust or support combustion.
7. China air tight door manufacturers have good anti-theft performance: China air tight door manufacturers have good hardware accessories and advanced decorative locks, so thieves are at a loss.
8. Maintenance-free: The aluminum-plastic composite profile is not easy to be corroded by acid, does not yellow or discolor, and almost does not require maintenance. Dirt, water and detergent are cleaned and cleaned.
The above is an introduction to the advantages and characteristics of china air tight door manufacturers.
