Product Description

CT Shape 14.8-25.3mm Thermal Break Polyamide Extrusion Strip

Production Description

Shape CT extrusion thermal barrier strip for aluminium window profiles. Inserted in the thermal break aluminium profiles, and being the part of energy-saving window system for reducing heat conduction. The shape CT polyamide thermal barrier material can prevent the window frame from dust and water, also has a more beautiful appearance than the shape I, could realize a better Uf value by sealing with a rubber profile, mostly used on the sash.
For the shape CT, 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.
