Homeowners can trim fuel bills by halting the heat loss that occurs at attic access doors, typically made of plywood with little insulating value (R-value: 1.7). The Insul-Door provides a high level of insulation (R-38) at the attic opening which is often overlooked when insulating an attic. Insul-Doors can be easily trimmed to fit the attic opening.
