Thermwell V96H Patio Door Insulation Kit 84x110 in

Product Description

The THERMWELL V96H is a patio door and picture window insulation kit designed to reduce drafts and heat loss through large door and window openings. The kit covers an area up to 84 inches wide by 110 inches tall and includes 42 feet of double-sided tape for a secure, wrinkle-free installation. It is intended for seasonal use in residential applications where air infiltration around patio doors or large picture windows is a concern. Contractors, weatherization crews, and capable homeowners typically install this kit as part of a broader energy-conservation or cold-weather prep scope.

This kit is suited for standard sliding glass patio doors and large fixed picture windows in residential settings. The film is applied to the interior side of the frame, creating an insulating air barrier over the glazed area. It is especially useful during heating season in climates with significant temperature differentials between indoor and outdoor environments. The 84-inch by 110-inch coverage accommodates most full-height patio door units without trimming.

Compatibility

Installation Notes

Installation is typically performed by weatherization contractors or homeowners during pre-heating-season preparation. Clean and dry the door or window frame thoroughly before applying the double-sided tape to ensure proper adhesion. Apply the film over the taped perimeter and use a heat gun or hair dryer to shrink the film taut, removing wrinkles. Remove the kit at the end of the heating season by peeling the tape carefully to avoid finish damage on painted or stained frames.
