SECTION OF SHAPES SYSTEM FOR ASSEMBLY OF WINDOW AND DOOR FRAMES, PARTITIONS, SHOWCASES AND STAINED-GLASS PANELS Russian patent published in 1998 - IPC

FIELD: civil engineering. SUBSTANCE: section of shapes system has outer and inner shapes with bends on inner faces and thermal insert having side flanges fixed in shape bends to form longitudinal channels. Installed in each channel is heat reflecting film from material based on polyethylene with low-emission layer of heat-preservation coating. Film thrusts projection made on flanges of thermal insert and freely bending to touch side surface of thermal insert. EFFECT: higher heat-insulating properties of structural frameworks. 2 cl, 1 dwg
