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.
Shape I, shape C, shape T, shape CT and shape HK is the most common shape, we can also according to customer requirements or drawings to customize other special shape.
