Product Description
Aluminium Windows Profile Polyamide PA66 GF25 Thermal Break Polyamide Strip

Product Description

What is Polyamide Insulation Profile?
1. Polyamide Insulation Profiles for Windows & Doors are made from resins that create a "thermal break" between the inner and outer surfaces of aluminum fenestration.
2. Polyamide insulation profiles for windows and doors reduce heat loss or heat gain through the aluminium.
3. Polyamide Insulation profile for windows and doors improve the U-value characteristics of finished systems.
4. Increasing use of thermal barriers to reduce heat gain and also reduce heat loss.
5. Stricter government regulations to reduce power usage in buildings to combat environmental concerns.

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.
