Product Description

PA66 Heating Barrier Tapes Polyamide Thermal Break Strips in Beoken Bridge Aluminum Windows and Doors
Product Introduction
Broken Bridge aluminum thermal break strip is an important criterion for distinguishing aluminum alloy doors and windows and broken bridge aluminum doors and windows.It is precisely because of the appearance of broken aluminum thermal break strips that the aluminum doors and windows of the broken bridge have good thermal insulation and sound insulation performance. The extruding high precision polyamide thermal break strip is used in windows and doors.Inserted in the thermal break aluminum profiles,it is the part of energy-saving window system for reducing heat sonduction.
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 of polyamide strips

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.

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.

 

PA strips 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.
