What is a polyamide thermal barrier strip?
What does a thermal break do?
A thermal break is defined as a material with low thermal conductivity placed in an extrusion with the purpose of reducing the flow of thermal energy (heat). In aluminum windows, three types of thermal breaks are used. A standard pocket thermal break has been used in the window industry for decades.

1. Sample water content less than 0.2% by weight.
2. Norm laboratory condition:(23±2)ºC and (50±10)% relative humidity.
3. The specifications marked with "a" only applies to I-shape strip otherwise, the specifications concluded between supplier and buyer through consultation, shall be written in contract or purchase order.
The polyamide strip is a material of low thermal conductivity which will minimise the transfer of heat and cold through the window frame, resulting in improved energy efficiency. The polyamide strip will have a HUGE impact in reducing transfer of heat and cold over typical non-thermal profiles. These sections can be anodized or powder coated to withstand the harsh climate, including UV damage and salt corrosion.
The wider the thermal break, the greater insulation performance.
Thermally Broken windows are a major contribution to sustainable and eco-friendly homes. They help to save money, energy and support the environment.
For all shapes, they could be packaged in linear, the length will be 6 meters or customized.
For the simple shapes like shape 'I' and shape 'C', they can be packed in rolls. 400-600 meters/roll.
