For some consumers, the knowledge of heat insulation is totally unknown. However, in recent years, due to the sales volume of bridge broken aluminum doors and windows in the market, coupled with people's praise for them, even if they don't know much about the door and window industry, they will also have some understanding of its characteristics. Know that the most important device of bridge broken aluminum doors and windows is the heat insulation strip, which can affect the quality of doors and windows.
The final quality of heat insulation strip of doors and windows
The broken bridge aluminum heat insulation strip is the black connecting material between the aluminum alloy materials, that is, if there is no black material, it is an ordinary aluminum alloy door and window. There are two kinds of black insulation strip, one is PVC, the other is nylon PA66. In terms of quality characteristics and life time, the nylon PA66 insulation strip is better. It has a good guarantee for the air tightness, water tightness, sound insulation and shockproof of doors and windows.
Glass fiber is generally used in the selection of reinforcement for heat insulation strips, which is only implemented in some European countries. Because it can improve the strength of the insulation strip, it can solve some defects of the material itself. In the production of heat insulation strip in China, due to the lack of technology, other materials are generally used to replace the strengthening degree. However, there are some other quality problems in the door and window.
The heat insulation strip of bridge broken aluminum doors and windows is made of nylon, which can ensure the strength, dimensional accuracy, heat resistance and so on. This is also the key to the thermal insulation performance of bridge broken aluminum doors and windows. That's what insulation strips do, if that's not possible. So the thermal insulation of broken bridge aluminum doors and windows is not so worthy of the name.
The quality of doors and windows will be used in the later stage, and the heat insulation function of heat insulation strip is reflected correspondingly. The doors and windows are well insulated and of excellent quality.
