PURPOSE: To provide a heating-type greenhouse capable of conducting optimal temperature controls suitable for a desired plant therein at a low space heating cost, or to provide a non-heating type greenhouse good in thermal insulation performance. CONSTITUTION: The main part of the foundation 10 of a greenhouse 90, or at least the surface layer of the indoor side of the foundation 10 is made up from a water-impermeable thermal insulation material, esp. expanded resin. |
