Thermwell DS101WH Self-adhesive Door Bottom 36 in White

Product Description

The THERMWELL DS101WH is a premium self-adhesive door bottom seal designed to block drafts, dust, and light at the base of interior and exterior doors. The flexible vinyl or foam construction compensates for uneven floors and carpet transitions, maintaining consistent contact along the full 36-inch span. Installation requires no tools or fasteners — the peel-and-stick backing adheres directly to the door face. This product is used by weatherization contractors, facility maintenance technicians, and experienced DIYers looking for a clean, low-profile sealing solution.

The DS101WH suits standard 36-inch residential and light commercial doors. The flexible design makes it appropriate for doors that sit slightly out of square or over thresholds with carpet on one side and hard flooring on the other. The white finish blends with painted door faces common in residential construction. It is appropriate for use on wood, metal, and most composite door materials.

Compatibility

Designed as a direct-apply weathersealing solution for standard 36-inch interior and exterior doors, including wood, metal, and composite door types with flat or near-flat bottom edges suitable for adhesive bonding.

Installation Notes

Clean and dry the door face thoroughly before applying the adhesive strip — oil, dust, or moisture will reduce bond strength. Measure and position the strip before removing the backing to ensure alignment along the full door width. Allow the adhesive to cure per the manufacturer's recommendation before cycling the door. No special tools or trade licensing is required for this installation, though facility maintenance staff or weatherization contractors typically handle commercial applications.
