Thermal insulation fast rolling shutter door

The reason why the thermal insulation fast rolling shutter door chooses polycool fiber cloth is that its surface temperature will not change due to the continuous change of cold storage and outside temperature. The surface hardness of ordinary PVC materials will change due to the change of temperature, and the surface cracking will occur within one to two years due to the continuous change of hardness. So thermal insulation fast rolling shutter door choose poly cool fiber cloth.
