Thermwell V449BH Brown Vinyl Foam Weatherstrip Tape

Product Description

The THERMWELL V449BH is a brown vinyl foam weatherstrip tape designed to seal gaps and drafts around doors and windows in residential and light commercial applications. The tape measures 0.75 inches wide by 0.1875 inches thick and comes in a 17-foot roll, providing enough material to seal a standard exterior door frame. The vinyl foam construction compresses against irregular surfaces to block air infiltration, moisture intrusion, and noise transmission. HVAC technicians, weatherization contractors, and skilled DIYers use this product as part of building envelope sealing work or as a supplement to duct and equipment access-panel sealing tasks.

This weatherstrip tape is suited for sealing gaps on door stops, window sashes, casement frames, and similar low-load contact surfaces. The brown color blends with wood-stained and darker-finished trim commonly found on entry doors and older window assemblies. Each roll covers approximately one standard door perimeter, making it practical for single-door retrofit jobs or stock replenishment on a service vehicle. It is available in package quantities of 24 rolls for shop or fleet stocking.

Installation Notes

Surface must be clean, dry, and free of dust or oil before applying the tape to ensure full adhesive contact. Measure and cut the tape to length before removing the backing, and press firmly along the full length of the door stop or window sash for consistent sealing. No specialized tools are required, though a utility knife and tape measure are standard for accurate fitting. Follow applicable building energy codes for weatherization requirements in the jurisdiction where the work is performed.
