Product Description

Durable Multi-Cavity Shape HK 35.3mm Thermal Barrier Bar for Curtain Wall Heat Protection Insulation 
Product Introduction

What is Polyamide Thermal Barrier Strips?

1. Pre-extruded profiles made from polyamide with 25 percent glass-fiber.
2. Locked in place in 'pockets' extruded into two separate (inner and outer) aluminum extrusions.
3. Enables finished assemblies with different finishes and colors on each surface.
4. Aluminum extrusion pockets need to be 'knurled' prior to insertion of the polyamide profiles-and 'rolled' to create a structurally-secure finished assembly.
5. 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.
6. 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.

Storage Conditions
The strips will be stored in the ventilated and dry environment, horizontally placed, paying attention to waterproof, keeping away from the heat source, avoiding heavy pressure and the contact with acid, alkali as well as organic solvent.

Delivery
We have the production capacity of 100000 meters per day. For common specifications, we have molds, and will be shipped in 7-15 working days after receiving the deposit. 

Packages
For all specifications/shapes, they could be packaged in linear, the length will be 6 meters, or customized.
For the Shape "I", "C", and some simple shapes, they can be packed in rolls. 400-600 meters/roll.
