Over the years, polyamide heat insulation strip has been widely used in glass curtain walls due to its good properties and low cost. Especially Polyamide 66 reinforced by 25% glass fiber thermal break strips, they are inserted into aluminum window, door and facade profile for thermal insulation.
The shape I 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 I, we can provide the following size or customize according to customers’ requirements.
Polyamide is a plastic that insulates more than 500 times better than aluminum, so thermal break profiles have a much lower Uf value – and transmit much less heat or cold. As a result, a building stays warmer in winter while keeping the heat outside more easily in summer.
Why are thermal breaks important? Thermal breaks are essential for any external modern glazing system. Thermal bridging can be responsible for up to 30% of a property's heat loss. This lowers the homes energy efficiency, leading to higher heating bills.

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.
If you have any specific questions, please contact us and we are happy to provide you with relevant services.
