Thermal washers are needed to attach polycarbonate sheets to the frame at specific points. This is one of the necessary components, which includes the washer itself made of plastic, a leg along its width, seals and a cap for snapping. The height of the plastic washer matches the thickness of the polycarbonate sheet.
Compared to ordinary washers, thermal washers look more aesthetically pleasing, they are simple to use and do not let the cold through where ordinary washers do. In addition, they prevent sheet deformation, do not prevent their expansion at high temperatures, do not allow the structure to collapse under wind loads, snowstorms, during hurricanes. Thermal washers of various colors and shapes are available to order at affordable prices.
