Abstract
Energy saving attachments for insulating attic access openings in the ceilings of houses or other buildings comprise insulating panels which attach from below to the outside of a swing-down door which closes the access opening, or to the ceiling around the access opening. The panels, which may be fitted to existing attic door installations, do not impede access to the attic, nor do they impede operation of the door or a folding stairway when such is carried by the door.
Claims6
An energy saving attachment for use in insulating an attic access opening, comprising a panel structure having a box or tray-like support member specifically dimensioned substantially to cover the access opening, thermal insulating material substantially filling the support member, and means for attaching the support member from below to a swing-down door closing the access opening, wherein the support member includes channel-like flanges along opposed longitudinal sides thereof and wherein the flanges and insulating material are dimensioned for sliding the panel structure into engagement with an outer panel of the attic door with said flanges gripping opposed longitudinal edges of the door to provide the attaching means.
In combination with an attic access opening in a ceiling having a swing door closing the opening, an energy saving attachment comprising a thermally insulating panel structure and means attaching the panel structure from below to the outer surface of the door with the panel structure projecting below the door to insulate the attic access opening when the door is closed, wherein the panel structure comprises a tray-like support member filled with insulating material, and the attaching means comprises channel-like flanges along opposed longitudinal edges of the support member which grip corresponding opposed longitudinal edges of the door when the panel structure is slid into engagement with the door.
