Thermwell V78/54H Insulation Mounting Tape 0.5x54ft

Product Description

The THERMWELL V78/54H is a double-faced insulation mounting tape designed to secure shrink film to window and door frames as part of indoor window and door insulation kits. Measuring 0.5 inches wide by 54 feet long, this crystal-clear tape provides a strong, clean hold without visible bulk. The double-sided adhesive construction keeps insulation film firmly in place throughout the heating season. This tape is intended for indoor use only and is sold in a package of 12 rolls, making it practical for contractors, property managers, and service techs handling multiple installs in a single visit.

This tape is used in residential and light commercial indoor weatherization applications. It is specifically designed for use with shrink film window and door insulation kits, where it functions as the primary bonding layer between the film and the frame surface. Typical install scenarios include seasonal energy-loss reduction on drafty single-pane windows and poorly sealed door frames. Compatible kits include models V6225 and V8425.

Installation Notes

Installation is a general weatherization task requiring no specialized trade license, though HVAC technicians and energy auditors commonly apply insulation kits during seasonal service calls. Clean and dry the frame surface thoroughly before applying tape to ensure full adhesion. This product is rated for indoor use only and should not be applied to exterior surfaces or in high-moisture environments. Remove carefully at the end of the season to avoid surface damage on painted or finished frames.
