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. The polyamide strip is a material of low thermal conductivity which will minimise the transfer of heat and cold through the window frame, resulting in improved energy efficiency. The polyamide strip will have a HUGE impact in reducing transfer of heat and cold over typical non-thermal profiles. These sections can be anodised or powdercoated to withstand the harsh Australian climate, including UV damage and salt corrosion.
The thermal performance of windows is affected by the interior environment of the building, external weather conditions, and the way the window is installed. Glass choices and glazing options have a significant impact on thermal performance as well. In addition, window frame modifications can be made. These "thermally improved" frames incorporate one or more thermal breaks, also known as thermal barriers.

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
It is mainly used in insulation broken bridge aluminium products, helping to reduce heat loss or heat gain through the aluminum, and has better performance in terms of power usage.
1. Expertise in the production of standard polyamide thermal break strips.
2. Respect customers' needs, provide customized products, try best to satisfy customers' requirements.
3. Fast service and on-time delivery
4. Strict quality control system, each production process will be strictly supervised by us.
5.We can provide all products on the insulation strip production line and the technical support.
