Buildings are constructed from various materials, including aluminium. Perhaps you make aluminium profiles and are already aware of what an excellent material it is for window and door frames. It's light and durable, it can withstand any type of weather and it's incredibly strong. However, without a thermal break it can cause problems as aluminium is also an effective heat conductor. Without a thermal break, your aluminium profile will be very hot in the sun and very cold in snow and rain. In effect, it draws heat in or out of its surroundings so if profiles today didn't have a thermal break we would face some of the problems that were common in the past. Not only is damp and condensation unpleasant, window frames without a thermal break can mean higher bills for heating. In extreme cases, damp can cause structural damage, so it's easy to see why thermal break profiles are the smart choice.
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.
