Sandwich panel for heating, cooling or for use as collector comprises central support to whose surfaces cover layers are applied, grooves in surface allowing pipes to be mounted below cover layer
Sandwich panel for heating, cooling or for use as a collector comprises a central support (1) to whose surfaces (11, 12) cover layers (22, 33) are applied. Grooves (13) in the surface allow pipes (33) to be mounted below the cover layer. These are slightly deeper than the diameter of the pipes. Independent claims are included for: (a) a method for making the panel by pressing cover layers on to the adhesive-coated surfaces of the support; and (b) use of the panel in roofs or facades in which the outside of the panel acts as a solar collector and the inner surface as part of a heating or cooling system.
