M-D 43846 All-Climate ThermaBlend Weather Seal, White, 17 Ft.

The M-D All-Climate ThermaBlend Weather Seal is a 17-foot self-adhesive weatherstrip designed to seal gaps and cracks around doors and windows. This wave-profile weather seal uses a durable EPDM and silicone rubber blend that expands and contracts with temperature changes, maintaining effectiveness even in extreme heat. It effectively blocks drafts, dust, and air leakage that can increase heating and cooling costs.

Whether you're weatherproofing a new installation or upgrading existing door and window seals, this flexible tape adapts to irregular gaps and uneven surfaces. The built-in adhesive backing makes installation quick and straightforward—simply peel and stick. You can cut the tape to length with scissors to fit any opening, providing a customizable solution for sealing gaps up to 3/8 inch.
