Protective greed containing four supports forming four-sided frame connected to the lateral and longitudinal filler elements integrated into the frame forming the greed is remarkable for its supports in the form of ?- shaped and ?-shaped profiles. Filler elements are in the form of metal bands with the cuts normal to their longer end and superimposed one on another through the cuts. Ends of metal bands are inserted into the cuts made in the frame support side surfaces and turned back at 90% and fixed on the same side surface. The other side surface of support is fixed on the building wall. Frontward around, the periphery the frame is superimposed by analogue fixed ?-shaped and ?-shaped profiles, the cuts can be made figured having the acute-angled protrusions on the longitudinal and lateral bands, and vice versa, on the opposed lateral and longitudinal bands it is remarkable for the discrete cuts forming the holes, in which the opposed band figured cut with the acute- angled protrusions are inserted, forming a latch, the cuts can be made figured having the rectangular protrusions on the longitudinal and lateral bands, and vice versa, on the opposed lateral and longitudinal bands it is remarkable for the discrete cuts forming the squeezed out protrusion of the tile form, which get in figured cats with a rectangular protrusions bands at insertion one in another by means of cats, forming a latch. |
