What Is The Definition Of Insulation Strips?


What is the definition of insulation strips?

The insulation strip is the core component of the threaded insulation profile, which serves as a "bridge break" in the heat transfer path of the aluminum profile, reducing the transfer of heat in the aluminum profile area; It is also the structural join of the aluminum profiles on both sides of the thermal insulation profile. Through its connection, the three parts of the thermal insulation profile become a whole and bear the load together. The insulation strip is different from the adhesive strip in that it is made of new composite materials through mechanical rolling and cannot be replaced separately. Replacement can only be done together with the entire profile.

The heat insulation strip is a kind of polyamide profile, which is composed of not less than 65% polyamide 66 and 25%+2.5% glass fiber. It is mainly used on aluminum alloy doors, windows and curtain walls to reduce heat conduction and structural join.

The classification of insulation strips can be divided into three types according to different production materials: PVC insulation strips using PVC (polyvinyl chloride) as raw material; PU insulation strip using PU (polyurethane) as raw material; Nylon insulation strips using PA (polyamide, commonly known as nylon) as the raw material.

In addition, insulation strips can be divided into two types according to different production processes: PVC insulation strips and PA insulation strips are both extrusion processes; The PU adhesive strip adopts an injection process.
