Thermal separation of windows, doors and façades

Plastic insulating bars are a vital component of modern window, door or façade systems made of metal. They separate aluminium frames thermally from each other, thereby reducing loss of heat to a minimum. Insulbar® insulating profiles are available in many shapes and different materials. Depending on the window type and climatic conditions, all requirements for a window system can be fulfilled.
