The new Warmatec frame is a combination of excellent parameters with high aesthetic value. It is made of two materials. The lower part is made of stainless steel, while the upper part is made of plastic, characterized by a low coefficient of thermal conductivity. This solution reduces the formation of a thermal bridge at the interface between the glass and the frame, and consequently reduces the Uw coefficient for the entire window. It can be used in all OKNOPLAST window systems. The Warmatec frame is available in black, brown and grey.
