The frame (1) for a greenhouse construction has a supporting core (2) screened by a casing (3). The core and casing are transparent, with the core made of unhardened glass and the casing formed by a plastic covering. The casing is an extruded profile with a rectangular cross-section, being provided on one side with an openable closure. The casing has two opposing walls (4,5), the outer ends of which are provided with snap-engaging edges, which form the closure.
