摘要

A greenhouse in which a foil (2) is affixed in a profiled frame (3) of 'V'-form by a snap-on frame (1) also of 'V'-form and in which at least one of the legs (3a) is provided with an extending edge (4). In a particular embodiment one of the legs of the profiled snap-on frame (1) is provided with another extending edge (5) and possibly a flap (6). The new construction has not only the advantage of simplicity but also the advantage that it is easy to fit and easy to remove.
