Product Description

Polyamide Thermal Insulation Bridge Strip For Thermal Break Aluminium Windows

 

Product Description

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

 

 

 

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.

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.

Application

Polyamide strip is one of the most common materials used for years to create thermal breaks in curtain walls, commercial windows, doors, and more. It is installed between the interior and exterior profiles of the windows that forms an insulating barrier between the two.

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.

Storage And Handling

Because PA66 is a hydrophilic substance, it will absorb the surrounding water. The rate and amount of water absorption depend on the ambient temperature, ambient humidity and storage period.

The relative humidity is higher in summer than in other short-term storage seasons. High moisture content (more than 2%) will affect the quality of wear-resistant strips.

 

When the insulation single bundle is removed from the shelf, it may be deformed. If it is not straightened in time, it will cause permanent deformation.

Therefore, it is recommended to keep it horizontal in a ventilated and dry environment, pay attention to waterproof, stay away from heat source, avoid stress and minimize bending.
