ABSTRACT:
A solar heat collector unit includes a solar heat collector having thermal-insulating material, e.g., fiber glass, provided against the outer absorber surface and a protective sheet over the insulating material. A generally U-shaped channel member is provided around the peripheral edges of the collector and protective sheet. The legs of the channel member engage the outer cover plate of the collector and the protective sheet to urge the collector and the protective sheet together about the thermal-insulating material.
