Evolution of the shape of the insulation strip

Time: 2023-06-25

Heat insulation strips appeared in China around 2000. At that time, the thermal insulation performance of aluminum doors and windows was extremely poor, and the thermal conductivity of aluminum was high. In order to improve the thermal insulation of the doors and windows, the aluminum was divided into two, and then a section of low thermal conductivity material was used to reconnect the two ends of the aluminum, and this section of material is our current thermal insulation strip. The insulation strip is an accessory connected to the middle of the aluminum alloy that can play a good heat insulation and thermal insulation effect. The insulation strip reduces the thermal conductivity of the aluminum, which in turn improves the thermal insulation effect of the doors and windows. The initial shape of the insulation strip is I-shaped, and later evolved into C-shaped, which has better thermal insulation effect than I-shaped.

In recent years, the cavity type heat insulation strips are more popular among the public. With the increasing heat insulation and thermal insulation performance requirements of door and window products now, the multi-cavity heat insulation strips have better thermal insulation performance to meet the heat insulation requirements. So, when you buy doors and windows, you should go more to compare and analyze. Can't just look at the price alone, the inner elements of the product is the core.
