Extrusion PA66 GF25 Thermal Break Insulation Strips Used In Aluminium Window Frame

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

The shape C 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 C, we can provide the following size or customize according to customers' requirements.

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.

Characteristic of PA strips

According to different storage time and ambient climate, the dimension of PA strips will increase slightly because of the natural moisture absorption. And the mechanical properties will change slightly too.

So, PA strips should be transported and stored under dry conditions away from the influence of weather. (rain, direct sunlight etc.)

Package & Delivery

Packaging details:

For all shapes, they could be packaged in linear, the length usually is 6 meters. Or we can customize based on customer's requirements. 

For the some simple shapes like 'I' shape and 'C' shape, they can be packed in rolls. The length usually is 400-600 meters per roll.
Delivery details:

shipped in 10-15 working days after receiving the payment
