Glass Fiber Reinforced Polyamide PA66 GF25 Thermal Break Strip Nylon Heat Breaking Strip
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
What does a thermal break do?
A thermal break is defined as a material with low thermal
conductivity placed in an extrusion with the purpose of reducing
the flow of thermal energy (heat). In aluminum windows, three types
of thermal breaks are used. A standard pocket thermal break has
been used in the window industry for decades.
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.
Why are thermal breaks important? Thermal breaks are essential for any external modern glazing system. Thermal bridging can be responsible for up to 30% of a property's heat loss. This lowers the homes energy efficiency, leading to higher heating bills.
