Thermwell DDS1 Double Draft Stop 36 Inches Brown

Product Description

The THERMWELL DDS1 is a double-sided draft stop designed to block air infiltration at the base of doors and windows. It insulates both the interior and exterior sides simultaneously, addressing drafts, dust, and energy loss in a single installation. The DDS1 measures 36 inches in length and features durable foam insulating rods housed in a washable fabric cover. It is adjustable, allowing it to fit doors or windows narrower than 36 inches. This product is suited for residential use and can be installed by homeowners, property maintenance technicians, or weatherization contractors working on building envelope improvements.

The DDS1 is appropriate for use on interior or exterior doors and windows in residential and light commercial settings. It performs on carpet, hardwood, and other hard floor surfaces. The brown color blends with common door and floor finishes. Its dual-rod design means one unit covers both sides of a door or window threshold, reducing the need for separate interior and exterior weatherstripping products at floor level.
