发明名称 Method of sealing an attic access opening and an insulated attic access cover
摘要 A method of sealing an attic access opening; a first step for which involves providing an attic access opening with a peripheral interior sidewall. A second step involves providing an insulated attic access cover, which consists of a first panel having a peripheral edge and a second panel having a peripheral edge. A flexible web connects the peripheral edge of the first panel with the peripheral edge of the second panel, and defines an insulation cavity between the first panel and the second panel filled with compressible insulation. A third step involves positioning the insulated attic access cover within an attic access opening and moving the first panel and the second panel toward each other to compress the insulation in the insulation cavity and cause the insulation to bulge outwardly to engage the peripheral interior sidewall of the attic access opening.
