A thermal break is, quite simply, a piece of material that's inserted between two pieces of aluminium. Today's thermal break material is normally made from a durable polyamide material. Until recently, however, aluminium thermal break window frames were made using a technique called pour and debrided. These vintage aluminium frames were made in one piece using an extrusion technique and were quite different to the thermal break profiles we deal with today. The frames would then be sliced in two so that two half scales are created. The hardened polyurethane holds the two pieces together. By comparison, modern thermal break material is about 1,000 times less conductive than the surrounding aluminium and that's an incredible amount of heat saved. This type of thermal break is created by inserting thin strips of polyamide into frames that are made in two separate halves.
The shape C thermal barrier polyamide strip can prevent the window
frame from dust and water, has a better mechanical performance, is
the first generation and easiest shape of insulating strips.
For the shape C, we can provide the following size or customize
according to customers' requirements.
