Abstract
A solar heat collector of the type having a pair of tempered glass sheets mounted in spaced relation to each other and to a solar energy and infrared absorber is provided with a vapor-impervious and moisture-impervious seal. The seal includes (1) a moisture-impervious adhesive to prevent moisture from moving between the glass sheets and absorber and (2) a vapor-impervious strip, e.g., an aluminum strip mounted between the adhesive and peripheral edge portions of the glass sheets and absorber to prevent solvent vapors of the adhesive from moving between the glass sheets and absorber.
