The airtightness of rapid roll up door and windows refers to the amount of air permeability per unit opening seam length or unit area of doors and windows. It assesses the ability of doors and windows to prevent air infiltration when they are closed. The airtightness of doors and windows has a greater impact on heat loss. The better the airtightness, the less heat exchange and the impact on room temperature. Also smaller. Therefore, improving the air-tightness of doors and windows is the key to energy-saving doors and windows. Our SEPPES zipper high speed door has good sealing, dustproof, insectproof, fast lifting and many other excellent properties.
The advantages of zipper fabric roll up door exported to the United States:
1. Efficient self-repair function: each zipper-type rapid doors is equipped with, when the door is hit, there is no need for any manual restoration, the door can be automatically repaired, which can improve the production efficiency of the factory and reduce the maintenance cost of the door.
2. High-strength airtightness: The door does not choose the traditional blade and brush sealing system. The close combination of the zipper and the guide rail of this zipper-type rapid roller shutter doors completely eliminates the generation of gaps, realizing a true seal and eliminating The inflow and outflow of air reduces heat loss and achieves energy saving.
3. Good safety performance: The door body adopts a safety soft bottom beam. When the door body is operating at high speed, the rolling door produced by Shanghai Express Door Factory can ensure the safety of pedestrians and vehicles, and ensure the safety of vehicles and goods.
4. Very high service life: the curtain adopts PVC coated wear-resistant base fabric, the opening speed of the variable frequency motor of the door can reach 2.5m/s, and the normal opening speed of ordinary fast doors is generally 2.0m/s. The door is oil-free The track allows the maximum wind resistance of the door body to reach 120km/h, and the operating life is up to 1.5 million times.
