The Attic Ladder Insulated Cover is the ultimate attic access insulation cover ever invented (attic ladder, scuttle holes, knee-wall doors, and full-size doors.) Its primary design is to stop air infiltration between the home and attic, the most common medium for wasting costly residential energy, during both hot and cold seasons. The HVAC systems in homes are designed for a closed envelope making air balancing with supply and return air, very critical. Every time these systems are operating they create a positive or negative pressure, thus forcing conditioned air out or drawing outside air in the home. It also keeps out unhealthy insulation and dust particles from the attic.
