Polyamide Thermal Break Bars Nylon Profile Heat Insulation Strip Used in Aluminum System Window

What is a polyamide thermal barrier strip?

1. Pre-extruded profiles made from polyamide with 25% glass-fiber.
2. Locked in place in ‘pockets’ extruded into two separate (inner and outer) aluminum extrusions.
3. Enables finished assemblies with different finishes and colors on each surface.
4. Aluminum extrusion pockets need to be ‘knurled’ prior to insertion of the polyamide profiles-and ‘rolled’ to create a structurally-secure finished assembly.
5. 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.
6. The aluminum extrusions can be finished either before or after installation of the polyamide strips.

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.

Advantages

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.
