摘要

The concealed system to prevent the distortion of window and door components of extruded polystyrene, through the effects of sunlight, is a frame of metal profiles (5) inserted into the lathes (C) forming the window/door panel. It is reinforced with dampers also using firm and unalterable metal profiles (3) inserted into the horizontal or vertical (F) members of the frame.
