Black Color Polyamide Thermal Break Insulation Strips for Heat Insulation Broken Bridge Aluminum Windows And Doors
What is a thermal break strip?
Thermal break is a reinforced polyamide strip (a non metallic, composite, structural, material) fixed between the inside and outside profiles, creating an insulated barrier within the window frame.
Why use polyamide to produce thermal break strips?
Polyamide is a plastic that insulates more than 500 times better than aluminum, so thermal break profiles have a much lower Uf value – and transmit much less heat or cold. As a result, a building stays warmer in winter while keeping the heat outside more easily in summer.
Can polyamide strips thermally break aluminum extrusion assemblies?
Yes.
Structural insulating polyamide strips have been utilized for thermally breaking aluminum extrusion assemblies for over 30 years and have been in use in north america for over a decade. Polyamide strips are available with many configurations to meet different performance specifications. Creating a thermal break utilizing a polyamide strip system entails a 3 step process.
1. Profile knurling
2. Strip insertion
3. Crimping

How to storage polyamide thermal break strips?
First, Store profiles horizontally in order to prevent bending or twisting the material, otherwise long storage periods cause permanent sagging. Support long lengths.
Second, Maintain ambient temperature in the range from 15 to 20 °C.
Third, Protecting against moisture.
