Thermwell V442H Foam Weatherstrip Tape 0.25x0.125x17ft Gray

Product Description

The THERMWELL V442H is a self-adhesive closed-cell polyvinyl chloride foam weatherstrip tape designed to seal gaps around doors, windows, and other building envelope penetrations where air and moisture infiltration occur. Measuring 0.25 inches wide by 0.125 inches thick and 17 feet long per roll, this gray tape compresses to fill irregular gaps and creates a waterproof, airtight barrier. The closed-cell PVC foam construction resists moisture absorption, making it suitable for both interior and exterior sealing applications. Installation requires no special tools, and the pre-applied adhesive backing bonds to clean, dry surfaces on contact.

This weatherstrip tape is used in residential and light commercial applications to reduce drafts, block moisture intrusion, and improve energy efficiency at door frames, window sashes, garage doors, attic hatches, and similar penetrations. HVAC technicians, general contractors, and maintenance professionals use this tape during new installation or retrofit work to address bypasses that compromise conditioned space performance. It is sold in a package quantity of 24 rolls per case.

Key Features

• Closed-cell PVC foam construction resists moisture absorption and compression set

Compatibility

Designed as a general-purpose weatherstrip replacement and sealing tape for residential and light commercial door frames, window sashes, garage doors, and similar gapped surfaces where a 0.25 inch wide by 0.125 inch thick foam profile provides adequate gap fill.

Installation Notes

Clean and dry all surfaces thoroughly before applying the tape to ensure proper adhesion. Power down any electrically operated door or window systems before servicing associated seals. This product is typically installed by HVAC technicians, general contractors, or maintenance personnel as part of air-sealing or weatherization work. Follow applicable building and energy codes, such as IECC requirements, for continuous air barriers in conditioned spaces.
