Product Description

C Shape 12mm Polyamide 66 Thermal Break Strip for Aluminium Window Profile


Production Description

Broken bridge aluminum insulation strip is an important criterion for distinguishing aluminum alloy doors and windows and broken bridge aluminum doors and windows. It is precisely because of the appearance of broken aluminum insulation strips that the aluminum doors and windows of the broken bridge have good thermal insulation and sound insulation performance.

The extruding high precision heat broken polyamide strut for windows and doors. Inserted in the thermal break aluminium profiles, and being the part of energy-saving window system for reducing heat conduction. The shape I, C, HK, T, CT, S and other polyamide thermal barrier material can prevent the window frame from dust and water and could realize a better Uf value, mostly used on the sash. We can make special laser marking on thermal barrier strips according to customers’ requirements.

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 C polyamide thermal insulation strip can prevent the window frame from dust and water, also has a more beautiful appearance than the shape I, but not so firm.
For the shape C, we can provide the following size or customize according to customers' requirements.

1. Effectively increased thermal in the system property insulation.
2. Reduces condensation on the window.
3. Sound insulated.
4. Improve comfort and living condition.
5. Possible double color coatings provide better aesthetic effect.
6. Various shapes will be designed for the customer's requirements.
7. The working temperature of the thermal insulation strip is 220°C, Melting Point reaches to 246°C. This enables coating process after assembly of composite profiles.
8. High corrosion-resistance, weather-resistance, heat-resistance, alkali-resistance and long life of usage.
9. linear thermal dilation coefficient almost identical to that of aluminium profiles.
