Product Description


China Professional Manufacture Hollow Type Polyamide Thermal Break Profile For Thermal Aluminum Windows


Product Description
Polyamide Insulation Profiles for Windows & Doors are made from resins that create a "thermal break" between the inner and outer surfaces of aluminum fenestration. They are used for windows and doors to reduce heat loss or heat gain through the aluminium as well as improving the U-value characteristics of finished systems. They increase the use of thermal barriers to reduce heat gain and also reduce heat loss. 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. 
Polyamide Thermal Break Strips for Aluminun Windows

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.

About Aluminum Bridge Profile

Thermal break strip, also called heat insulation strip, is a part of aluminum bridge profile. The heat-insulating bridge aluminum-plastic profile can realize the three-way sealing structure of doors and windows, and reasonably separate the water vapor chamber. It successfully realizes the pressure equalization of gas and water, and significantly improves the watertightness and airtightness of the doors and windows.
