Thermal insulation aluminum extrusions are important components in any door and window system. It refers to the reinforced polyamide strip between the internal and external aluminum profiles, which forms an insulating barrier in the window frame. More exactly, it makes the aluminum framed window form a barrier between the inner and outer sashes to prevent heat conduction loss.

We provide aluminum frame profiles for windows and doors for architectural projects, usually using aluminum alloy 6000 series materials. These include 6061, 6063, 6082, 6463, etc. They are also typically tempered to a T3, T4, T5 or T6 condition to increase hardness. Surface treatment options include anodizing, electrophoresis, powder coating, PVDF, and wood grain patterns.
Of course, we also customize aluminum windows and doors for customers in Saudi Arabia, Mexico, Thailand, etc. We customize aluminium window and door frame profiles in different sizes, thicknesses, colors or different required functions according to the standards of other countries or customer requirements. Also, we can produce finished aluminum doors and windows for you.

It involves using a hydraulic press to push the billet through the die to create the desired window or door aluminum profile.

In essence, it is the natural finish the extruded aluminum profiles have the moment they emerge from the extruder die.
