Maintain comfortable temperatures with the ThermoClimb Adjustable Attic Stairway Insulator. An average attic will lose up to 27% of its total insulating properties without insulating the 10 sq. ft. of space over your attic door. To fight back against this, choose an attic stairway cover, or attic tent, such as ThermoClimb, to significantly raise your attic's thermal insulation.
