Abstract of the Disclosure An energy efficient skylight construction. A skylight cover is secured by a frame to a curbing comprised on an insulat- ing core, the interior and exterior surfaces of which are covered by non-combustible shields separated along the upper and lower surfaces of the curbing by a gap which serves as a "thermal break" between the highly conductive inner and outer shields. The frame is pierced by drain openings the exterior of which are covered by a filter type material such as foam or glass fibers that is both absorbtive of moisture and resistant to the passage of air. The frame is secured to the outward portion of the curbing and includes a flange extending inward across the gap between the shields, which serves as a gutter to collect condensation which drips off the glazing. The inward portion of the flange is covered with an insulating gasket which prevents condensation from forming on the flange and which prevents the warmer, more moisture laden, inside air from reaching the cold underside of the gutter flange or the edge of the outer skin. The core insulation is inserted, without adhesives, into the assembled inside skin, and then the exposed surface of the insulation is bonded to the in- side surface of the outer skin. 1.
