The greenhouse consists of frame parts assembled from supports, crossbars, purlins and rails formed from profiled bars. Inserted into the frame parts, with interposition of seals, are filling plates made of glass, transparent plastics or the like, the profiled bars having support legs for supporting the filling plate. To reduce the variety of types, the support legs of the profiled bars are connected to strips which supplement the thickness of the filling plates.
