Stairseal

Abstract

A sheet metal enclosure containing a thickness of Styrofoam Insulating material designed to slide over the plywood panel on attic stairways. A rubber seal is placed on the perimeter of the back side of the panel creating a seal between the living area and attic space reducing air transfer between the two spaces. The Styrofoam provides an amount of insulation reducing temperature transfer between the two spaces. The sheet metal panel provides for the containment of the insulating material and mounting surface for the rubber seal and reduces warping of the attic stairway plywood panel because it is held rigid within the confines of the metal enclosure containing the Styrofoam. The closure springs on the attic stairway provide the tension to hold the stairway closed and create a tight seal.

What is claimed:  
     
         1 . The rubber seal prevents air transfer between living areas and attic space.  
     
     
         2 . The Styrofoam provides insulation against thermal transfer between the living and attic space.  
     
     
         3 . The steel panel provides for containment of the insulation, mounting of the rubber seal and strengthens the plywood access panel preventing warping while sealing and insulating the attic stairway opening thereby reducing air and temperature transfer leading to reduced utility bills and power consumption.
