American injection molded insulation aluminum profiles: After the overall aluminum material is extruded, polyurethane adhesive is built into the inner and outer connection grooves to block the internal and external heat conduction of the aluminum material.
European style strip insulated aluminum profiles: The inner and outer aluminum profiles are extruded separately, and then the inner and outer profiles are rolled and compounded together with glass fiber (GF) reinforced polyamide nylon (PA66) insulation strips, which block the internal and external heat conduction of the aluminum materials.
The current mainstream market is European style strip insulated aluminum doors and windows. The main reason is that European style insulated aluminum windows are easy to achieve dual color inside and outside (with different surface treatments of profiles inside and outside), which can intuitively reflect the product attributes of insulated aluminum alloy doors and windows; The implicit reason is that the European aluminum door and window system is more mature, the cooperation of supporting materials is more mature, the systematic structural design is more abundant, and the domestic reference samples are more diverse.
The reason why insulated aluminum doors and windows have become the origin of aluminum door and window systems is that insulated aluminum windows, as composite structures, have multiple specifications of aluminum profiles and diverse structural designs. In order to pursue the universality of profiles, it is necessary to carry out pre system design, especially the matching design between the three major components of door and window materials - profiles, hardware, and glass profiles and hardware.
