Fast rolling doors are divided into pvc fast doors and hard fast doors according to materials. Since the facade of the pvc fast door is made of industrial woven fabric, it generally plays the role of fast partition in daily use, so when there is a need for heat preservation, a hard fast door is required to meet the use requirements. So for a high-quality hard fast door , we should pay attention to which processes can improve its thermal insulation performance, while taking into account other use requirements! Let's take a look.

The hard fast door panel is made of aluminum alloy and filled with polyurethane foaming agent. Commonly used specifications for the thickness of hard fast doors are: 43mm , 60mm , and 80mm . The thicker the door, the better the insulation performance. We all know that aluminum alloy is a heat-conducting material, so no matter how thick the door panel is, it is necessary to use a broken bridge design to separate the aluminum alloy on both sides of the door panel, so as to improve the overall thermal resistance of the door panel and reduce the heat loss of the door panel.

In the usual environment, most of the ambient heat is transferred through airflow, so enhancing the sealing performance of the fast rolling door can improve the heat insulation performance of the hard fast rolling door. The sealing of the hard fast door is mainly reflected in two places, the first is the link between the door panels; the second is the installation method.

In general, the outer surface of the door panel of the hard fast door is connected with a sealing strip, which requires that the error between the R -shaped groove on the side of the panel and the sealing strip should be within 10 lines during the stretching process of the door panel , so that the sealing strip can be tightly connected to the door panel. touch. In addition, when the airflow hits the door panel, it enters the narrow space in the gap between the door panels. During this process, the airflow speed will be accelerated by the air pressure. Therefore, it is not only necessary to add a sealing strip on the surface of the door panel, but also to add a rubber strip on the inner surface of the door panel to play a buffer role. The role of gas circulation, so that even in windy weather, the hard fast door can also have good sealing performance.

Generally speaking, experienced installation teams will notice when installing hard fast doors that after the hard fast doors are installed, sealing must be done around the door frame. Running speed is the unique advantage of hard fast doors . The faster the door runs, the faster the convective flow of the two gases can be cut off. Generally, when the hard fast door is actually used, the speed is between 0.8m/s and 2m/s .
