What is Polyamide Thermal Barrier Strips?
- Pre-extruded profiles made from polyamide with 25 percent glass-fiber
- Locked in place in ‘pockets’ extruded into two separate (inner and outer) aluminum extrusions
- Enables finished assemblies with different finishes and colors on each surface
- Aluminum extrusion pockets need to be ‘knurled’ prior to insertion of the polyamide profiles-and ‘rolled’ to create a structurally-secure finished assembly
- The polyamide profiles can be supplied with ‘sealing-wire’ which give a reliable seal and enhanced shear strength when activated by heat e.g.-powder coating
- The aluminum extrusions can be finished either before or after installation of the polyamide strips
Advantages
Polyamide is a plastic that insulates more than 500 times better than aluminium, so thermal break profiles have a much lower Uf value - and transmit much less heat or cold. As a result, your home stays warmer in winter, while keeping the heat outside more easily in summer.
Application
Thanks to the development of a new invention known as thermal break profiles. If you install polyamide strips in aluminum windows, they are at least as good as its competitors. In these profiles, produced with specialized machines, a polyamide strip is placed between the inner and outer sections of the profile.

According to different storage time and ambient climate, the dimension of PA strips will increase slightly because of the natural moisture absorption. And the mechanical properties will change slightly too.
So, PA strips should be transported and stored under dry conditions away from the influence of weather. (rain, direct sunlight etc.)
