The door and window insulation strip is the central component of the thermal insulation profile and the structural connector of the aluminum profiles on both sides of the thermal insulation profile.

The door and window insulation strip is the central component of the thermal insulation profile and the structural connector of the aluminum profiles on both sides of the thermal insulation profile. Through connection, the three parts of the thermal insulation profile are connected to bear the load together. Its role is to reduce the heat transfer of aluminum profiles. Now, it is important to understand the lower door and window insulation strips together!
How to select thermal insulation strips for doors and windows
1. The quality of the material can be seen from its surface. The surface of good quality is very smooth, and the color distribution is very balanced. The surface of cross-linked aluminum alloy doors and windows with poor quality is very rough, and the color is uneven.
2. The material thickness is strictly regulated for cross-linked aluminum alloy doors and windows in China, and the material thickness shall not be less than 1.2mm. The strength per square meter is about 157 N, and the thickness of the oxide film should be more than 10 microns. If these conditions are not met, it is difficult to ensure the quality of products.
3. It depends on the workmanship. In the process of processing, we should carefully process. Be flexible in switching. If the sealing is not good, the effect will be ignored. Ordinary inferior doors and windows are poorly made and can't be opened and closed properly. Sometimes air and water leaks occur.
4. Generally, the angle of material section shall be accurate. The surface of the glass material needs to be smooth to avoid twists and turns.
5. Choose brand products. There are many bridge cutoff aluminum brands in the market. Make sure to choose a brand with good quality and after-sales service, and ensure the service life and installation effect
At present, the heat insulation strips for doors and windows sold on the market are made of PVC heat insulation strips and pa66 nylon heat insulation strips. However, due to consumers' blind spots in knowledge, they may be punched by illegal businesses when buying. Therefore, if you don't want to harm your own interests, we suggest you learn how to distinguish between PVC insulation sheet and pa66 nylon insulation sheet.
After purchasing the door and window insulation strip, you can compare it from the appearance, hardness and flame retardancy. For example, appearance. PVC insulation strip is gray black, with uneven surface; The nylon insulation strip of pa66 has a pure black appearance and a smooth and flat surface. For example, as far as the hardness is concerned, the heat insulation strip made of PVC is poor in hardness, and it is difficult to break even if it is folded in half. It is easy to deform and fall off when the temperature difference is large; On the other hand, the nylon insulation sheet of pa66 is not easy to deform due to its brittleness and high hardness to a certain extent. It is easy to break if it is folded in half. For example, in terms of flame retardancy, the heat insulation sheet made of PVC has poor flame retardancy, and when ignited, it will have a pungent smell and emit black smoke. On the other hand, the nylon insulation strip of pa66 is difficult to burn. Even if it is ignited, it will not produce black smoke, which has the smell of burning wings.
Through comparison, experience can be summarized. That is, when buying door and window insulation strips, you can distinguish between PVC or PA66 materials by baking, folding and touching.
