Durable Multi-Cavity Shape HK 35.3mm Thermal Barrier Bar for Curtain Wall Heat Protection Insulation
Product Introduction
What is Polyamide Thermal Barrier Strips?
- Pre-extruded profiles made from polyamide with 25 percent glass-fiber.
- Locked in place in 'pockets' extruded into two separate (inner and outer) aluminum extrusions.
- Enables finished assemblies with different finishes and colors on each surface.
- Aluminum extrusion pockets need to be 'knurled' prior to insertion of the polyamide profiles-and 'rolled' to create a structurally-secure finished assembly.
- The polyamide profiles can be supplied with 'sealing-wire' which give a reliable seal and enhanced shear strength when activated by heat e.g.-powder coating.
- The aluminum extrusions can be finished either before or after installation of the polyamide strips.
Product Advantage:
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.
