Thermwell V85M Window Insulation Kit 62x210 in Extra Large

Product Description

The THERMWELL V85M is a heavy-duty window insulation kit designed to reduce drafts and heat loss through residential windows during cold-weather months. The kit covers an area of 62 inches by 210 inches, making it suited for larger window openings or multiple standard windows in a single installation. It provides a thermal barrier that helps retain interior heat and block cold air infiltration. Licensed contractors, weatherization specialists, and knowledgeable DIYers install this type of kit as part of a seasonal energy-efficiency routine. The V85M is packaged in a quantity of six units per package, allowing for whole-home coverage in a single order.

This kit is intended for residential applications where windows are a primary source of heat loss or draft infiltration. It is commonly installed over single-pane windows, older double-pane units with failing seals, or any window opening that is not adequately weatherized for winter conditions. The extra-large dimensions allow the film to span wide window frames or sliding glass door surrounds without piecing. Typical installation requires no specialized tools, and the process is designed to be completed quickly across multiple windows in a single session.

Installation Notes

Window insulation kits of this type are typically installed by homeowners or weatherization contractors as a seasonal measure. Clean and dry the window frame surface thoroughly before applying any adhesive strips to ensure proper adhesion. No cutting tools beyond standard scissors are typically required. Remove the film carefully at the end of the heating season to avoid damage to window trim or painted surfaces.
