Polyamide PA66 GF25 Heat Resistance Thermal Break Strip Heat Insulation Strip Used for Windows and Doors
Product Introduction
What is thermal insulation strips?
High Precision For Aluminum Sash Window Frame PA66 25% Fiberglass Thermal Insulation barrier strips.
Inserted in the thermal break aluminium profiles, and being the part of energy-saving window system for reducing heat conduction.
The shape I polyamide thermal barrier material can prevent the window frame from dust and water and could realize a better Uf value by sealing with a rubber profile, mostly used on the sash.
Features:
1. The working temperature of the thermal insulation strip is 200°C. This enables coating process after assembly of composite profiles;
2. High mechanical strength, able to connect with metal hardware fittings when bearing draw and shear stress;
3. Excellent product tolerance of less than 0.1mm, ensuring air and water tightness and overall composite profile dimensions;
4. High corrosion-resistance, weather-resistance, heat-resistance, alkali-resistance and long life of usage;
5. The thermal expansion coefficient of PA66GF25 is similar to aluminum thus ensures that product does not affect the integrity of the thermally insulated aluminum profiles;
6. Precisely dimension ensures the lifespan of aluminum extrusion tools, no danger of bending cracks during rolling, very good knurling effect at the hammer head and easy to assemble.

Application and Advantages
Aluminium window has the disadvantage of limited thermal insulation. Its Uf value, which indicates the amount of heat that passes through a window profile, is simply too high. If your windows have standard aluminium profiles, your home may develop condensation, or even mould. Besides the resulting high repair costs, household mould also aggravates respiratory problems such as asthma.
But that disadvantage has now been completely eliminated if you install polyamide strips in aluminum windows. In fact, thanks to the development of a new invention known as thermal break profiles, aluminium is at least as good as its competitors. In these profiles, produced with specialized machines, a polyamide strip is placed between the inner and outer sections of the profile.
Polyamide is a plastic that insulates more than 500 times better than aluminium, so thermal break profiles have a much lower Uf value - and transmit much less heat or cold. As a result, your home stays warmer in winter, while keeping the heat outside more easily in summer.
Storage
First, Store profiles horizontally in order to prevent bending or twisting the material, otherwise long storage periods cause permanent sagging. Support long lengths.
Second, Maintain ambient temperature in the range from 15 to 20 °C.
Third, Protecting against moisture.
