Customized PA Heat Breaking Strip, PA66 Thermal Insulation Weather Stripping For Aluminum Windows
What are the different types of thermal barriers?
Currently, there are two principal types of thermal barriers: polyamide thermal barrier strip and pour & debridge (P&D).
Our company only produce polyamide thermal barrier strip.
Why use Polyamide Profiles as thermal barrier?
The coefficient of linear thermal expansio (linear elongation coefficient) of the polyamide profiles is equivalent to the aluminum profile. Therefore, the polyamide profile is not subjected to internal stresses after it is pressed to aluminum profile. This is one of the most important advantages of using the polyamide material as a thermal barrier.
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.
What is a Thermal Barrier?
- Thermal barriers are made from resins that create a “thermal break” between the inner and outer surfaces of aluminum fenestration.
- Thermal barriers reduce heat loss or heat gain through the aluminum.
- Thermal barriers improve the U-value characteristics of finished systems.
- Thermal barriers are about energy conservation, U-values and government codes
- 70 percent of aluminum fenestration systems produced in North America contain a thermal break
- Primarily used in colder climates to reduce heat loss
- Increasing use of thermal barriers to reduce heat gain and also reduce heat loss
- Developers, architects and designers are demanding better performance in terms of power usage
- Stricter government regulations to reduce power usage in buildings to combat environmental concerns
- Aluminum, if it is to retain its market superiority in terms of its structural integrity, will have to achieve better performance in terms of U-values
- The use of thermal barriers will assist manufacturers to achieve improved LEED performance
