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.
PA66 GF25 windows insulated aluminum parts polyamide thermal break strips.
Polyamide PA66 thermal break strips has high mechanical,high heat deflection temperature,high precision in size.
we have great advantage especially in thermal break strip for heat insulation aluminium windows,aluminum doors aluminum profile,aluminum fence and curtain wall, etc.
The shape C thermal barrier polyamide strip can prevent the window frame from dust and water, has a better mechanical performance, is the first generation and easiest shape of insulating strips.
For the shape C, we can provide the following size or customize according to customers' requirements.
high quality, competitive price, free sample support and short lead time, high mechanical strength, high toughness, high softening point, good wear resistance, self-lubrication, long-term work at higher temperatures, high CTI value, excellent electrical insulation, low smoke and toxicity characteristics.
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.
According to different storage time and ambient climate, the dimension of PA strips will increase slightly because of the natural moisture absorption. And the mechanical properties will change slightly too.
So, PA strips should be transported and stored under dry conditions away from the influence of weather. (rain, direct sunlight etc.)
