Abstract
A draft insulator kit for use with an attic pull-down staircase comprises a dimensioned enclosure held together with plastic rivets and resting on weather stripping placed directly on the framing around the pull-down staircase. The edge of the box rests on the weather stripping to seal against drafts. The insulator can be covered with fiberglass batting to increase R value but is itself a cost-effective seal against drafts. It can be folded for increased shipping efficiency, is made of low cost cardboard, and has low manufacturing costs. As a result, its payback time to the consumer is less than one season.
