Thermal insulation door is actually a function enhanced fast rolling door product. It is a double layer composite door curtain with thermal insulation material and a built in sealing structure for the track. It has certain wind resistance and fast opening speed. So how does it play the role of heat preservation? Woolen cloth?

        1. The double layer composite thickened door curtain is filled with thermal insulation materials to reduce heat transfer and achieve better thermal insulation effect;

        2. Double rows of nylon brushes or EPDM strips in the track are sealed to block air convection and promote heat preservation;

        3. The top, bottom and both sides of the door are in a sealed state, effectively reducing the air circulation, so as to achieve the effect of heat preservation.

        The thermal insulation effect of the thermal insulation door is significantly improved compared with that of the ordinary fast rolling door. It is suitable for ordinary cold storage areas or special environments that require thermal insulation. And we can choose track heating system device to prevent condensation and freezing.
