Description

Technical Field

[0002] In the northern region, building doors and windows are generally plastic steel doors and windows or aluminum plastic composite doors and windows. There are many types of aluminum plastic doors and windows on the market. In order to adapt to the northern climate and prevent the indoor temperature from being too low due to the outdoor temperature being too low, generally, a heat insulation cold bridge is used between the inner profile and the outer profile to achieve the insulation effect. The insulation strip is the core component of the through-strip insulation profile. It is the "broken bridge" on the heat transfer path of the aluminum profile, reducing the heat transfer in the aluminum profile. It is also the structural connector of the aluminum profiles on both sides of the insulation profile. Through its connection, the three parts of the insulation profile become a whole and bear the load together.

[0003] The insulation strip is generally a structure in which a metal profile is wrapped with plastic. However, in actual use, the outer plastic structure is easy to fall off the metal profile, which not only affects the sealing, but the exposed metal profile will also affect its thermal insulation performance.
