Insulation strips are indispensable accessories for doors and windows to improve sealing. When choosing to use, we must pay attention to making sure that the selected product can achieve the desired effect. So how should we choose heat insulation strips for doors and windows? This is a question I want to introduce to you today, let's take a look at it below.
The selection of door and window heat insulation strips should be judged from the aspects of wind pressure resistance, water tightness, air tightness, thermal insulation, and sound insulation. The heat insulation strip is the most critical part of the aluminum profile for the broken bridge, so PA66 nylon must be used for production. This is stipulated by the national standard. However, there are still many cheap PVC plastic insulation strips in the current decoration market. The service life of this kind of aluminum-plastic doors and windows is much shorter, and even if the PVC heat insulation strips are installed, they will not play much role.

Insulating aluminum alloy is to divide the original integrated profile into two parts on the basis of traditional aluminum alloy, and then connect the separated parts together by mechanical compounding of the two heat insulation strips, so that the aluminum-plastic Doors and windows have high strength and reduce their conductivity, otherwise there will be hidden safety hazards or the meaning of heat insulation strips will be lost. Therefore, when choosing aluminum-plastic doors and windows, the material of the heat insulation strips is the most critical.
The above introduces you to the basic points that you need to pay attention to when choosing heat insulation strips for doors and windows. I hope that the above introduction can bring you some help.
