Roller shutter boxes made of wood fiber, plywood or foams are known, which can be placed on the wall as a prefabricated part or can be walled in. All serve rolling wheels ^; They have the disadvantage that because of their materials, e.g. wood construction, have no load-bearing capacity for the masonry on top. Wood is also unsuitable for walling in. It shrinks or expands in the masonry and cracks tend to form on the plaster or otherwise become apparent due to the effects of temperature. It is also a disadvantage that the roller shutter inlet slot has to perceive a larger amount of air because of the passage and is therefore strongly cooled by the wind inside, which, on the other hand, requires more heating costs for the living space. The unsealed inlet slot not only provides poor cold insulation, but also the sound penetrates into the living space.

It was therefore necessary to look for a new roller shutter construction that remedied this deficiency. The registration subject brings quite a significant improvement with it. As can be seen from the drawing, this roller shutter box consists essentially of Edged steel profiles, which naturally have a high load-bearing capacity and are not subject to any stretching, wood or the like. These steel profiles are folded in such a way that the insulating panels on the inside and outside serve as plaster bases serve, can be pressed in tightly with. For further stiffening, these steel profiles are additionally stiffened in the vertical direction with so-called sink marks. The upper steel cover board, as well as the roller holder bearing is in one piece at the corners fourth] bevelled round and firmly welded to the side panels. This results in an extremely stable steel structure, which is what most In cases a so-called window lintel is superfluous. This construction is particularly useful for conversions where wooden bellows are above it And to insert an extra concrete window lintel no more!
