Thermwell V93H Outdoor Window Insulation Kit 42x62 in

Product Description

The THERMWELL V93H is an outdoor window insulation kit designed to reduce drafts and heat loss at standard residential windows. The kit includes one clear plastic sheet measuring 42 inches by 62 inches along with a roll of double-sided tape measuring 0.5 inches wide by 18 feet long. The sheet installs on the exterior or interior window frame to create an insulating air barrier, helping to maintain indoor temperatures and lower heating load during cold weather. HVAC technicians, weatherization contractors, and knowledgeable homeowners typically install this kit as part of a broader energy-efficiency or winterization service.

The V93H is sized for standard windows and is well suited to residential applications where single-pane or older double-pane windows allow significant air infiltration. It is commonly used in seasonal weatherization work, rental property turnover prep, or as a temporary measure while awaiting window replacement. The included tape provides a complete, ready-to-install package with no additional adhesive required for most applications.

Installation Notes

Installation is typically performed by weatherization contractors or HVAC technicians as part of a seasonal service. Clean the window frame surface thoroughly before applying the tape to ensure proper adhesion. Follow local building and energy codes for exterior insulation applications. Remove the sheet and tape at the end of the heating season to allow normal window operation.
