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 CT 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 CT, we can provide the following size or customize according to customers' requirements.
It is mainly used in insulation broken bridge aluminium products, helping to reduce heat loss or heat gain through the aluminum, and has better performance in terms of power usage.
