The 40 mm thick panels with the proven tongue and groove connection are 500 mm wide. The panels differ in the number of shells, which have a significant influence on the U-value. The U-values of these panels range from 1.5 to approx. 1.0 W/m²K, depending on the selected product and the installation situation. The frame profiles are available in thermally separated and non-thermally separated versions. The panels can not only be optimally installed in the façade area, but also offer ideal and durable solutions for roof glazing.
