The main function of a thermal break system is to separate an aluminum profile into two parts to reduce thermal conductivity in a window. The two ways of doing this are by using poured polyurethane (pour and debridge), or using a polyamide structural insulating strip system.
Alutions offers two methods:
Pour and Debridge (P&DB)
This Method offers improved thermal performance in a single piece of extrusion. The process consists of filling a pre-extruded cavity in the profile with resin that then hardens. Subsequently, we cut a small section of aluminum on both sides of the filling zone, dividing the profile in two parts. When assembly is done, the resin isolates the exterior and interior parts of the system. This thermal barrier enhances the resistance to condensation and offers an alternative for areas of high and low temperatures. Clients will be able to control the interior thermal conditions, and save lots of money on energy.
Polyamide Structural Insulating Strips
This system involves joining two separate extrusions through the use of an engineered structural insulating strip. Both the inside and outside aluminum profiles are extruded independently with a cavity that will ultimately receive the strip and produce a true mechanical connection of the two frames. Structural insulating strips made of polyamide have been the chosen method of thermally breaking aluminum fenestration products for more than thirty years overseas.
