Thermal Break Insulation Tapes Polyamide Thermal Break Strips Used In Broken Bridge Aluminum Windows And Doors
Product Description
What is a thermal break strip?
Thermal break is a reinforced polyamide strip (a non metallic, composite, structural, material) fixed between the inside and outside profiles, creating an insulated barrier within the window frame.
Can polyamide strips thermally break aluminum extrusion assemblies?
Yes.
Structural insulating polyamide strips have been utilized for thermally breaking aluminum extrusion assemblies for over 30 years and have been in use in north america for over a decade. Polyamide strips are available with many configurations to meet different performance specifications. Creating a thermal break utilizing a polyamide strip system entails a 3 step process.
1. Profile knurling
2. Strip insertion
3. Crimping
What are the different types of polyamides?
Polyamide (PA) Polyamides are among the most important and proven technical thermoplastics, known for their heat resistance, stiffness and high mechanical stability Polyamides can be classified into different types, with PA 6, PA 6.6 and PA 12 most established on the market.
Our polyamide strips are made of PA6.6 reinforced by 25% fiberglass.
Advantages of using polyamide strips:
They provide a better thermal insulation
They need lesser use of metals
The polyamide strips are cost-effective
They are easy to create thermal barriers with
They help in resources to be conservedand can reduce operating costs
They ensure maximum stability of the structure
They are more than effective in resisting condensation
They don’t require any special handling or fabrication
Application
Polyamide strip is one of the most common materials used for years to create thermal breaks in curtain walls, commercial windows, doors, and more. It is installed between the interior and exterior profiles of the windows that forms an insulating barrier between the two.

1. Sample water content less than 0.2% by weight.
2. Norm laboratory condition:(23±2)ºC and (50±10)% relative
humidity.
3. The specifications marked with "a" only applies to I-shape strip
otherwise, the specifications concluded between supplier and buyer
through consultation, shall be written in contract or purchase
order.
PA strips storage and handling:
Because PA66 is a hydrophilic substance, it will absorb the surrounding water. The rate and amount of water absorption depend on the ambient temperature, ambient humidity and storage period.
The relative humidity is higher in summer than in other short-term storage seasons. High moisture content (more than 2%) will affect the quality of wear-resistant strips.
When the insulation single bundle is removed from the shelf, it may be deformed. If it is not straightened in time, it will cause permanent deformation.
Therefore, it is recommended to keep it horizontal in a ventilated and dry environment, pay attention to waterproof, stay away from heat source, avoid stress and minimize bending.
