Heatable greenhouse floor - has channels between top and bottom layer connected by passages to top surface

摘要

The heatable floor is particulary for plant cultivation in greenhouses. It has a lighter layer of heat-insulating material on which a heavier load-supporting layer rests. Channels (11) are formed in the mating faces of the two layers (5,6). Passages (13) are formed in the top one between the channels and the top surface for water and/or air. The grooves can be formed in the bottom layers only and both layers can comprise detachable prefabricated plates.
