INTEGRAL is a unique line of products in simple form with narrow frames and fixed glazing impression. This creates a visual effect of a single frame, just like in fixed windows. These system profiles were developed without a visible slant and, as a result, create an external right angle. The use of an additional welded gasket in the frame profile increased the overall tightness of the construction which resulted in obtaining the E1200 classification, approved by IFT Rosenheim tests.
