FIELD: construction.

SUBSTANCE: invention relates to the window and door translucent structures production (or repair) technologies from different types of materials: plastic (PVC), aluminium, wood, glass composite, etc, in particular, to methods of stabilizing shape of rotary and rotary-inclined flaps in windows and doors against sagging.
