<p>The small greenhouse has a transparent sheet, esp. made of glass, which is held by a frame. The sheet frame (10) has a metal base section (8) which is separated from the sheet (12) by thermally insulating material (16, 36). Specifically, the frame base section (8) has an outside opening cavity (14) which encloses a core (16) of thermally insulated material. There is a slot (28) in this core (16) to accept the longitudinal shank (30) of a T-section sheet holding strip (32) which grips on a sheet (12) at a cross shank (34) and presses against a thrust bearing (36).</p> |
