Indoor Window Insulator Kit 7 ft x 19.7 ft

The 3M Indoor Window Insulator Kit delivers a complete window insulation solution for homeowners seeking to reduce drafts and improve energy efficiency during colder months. The kit covers up to ten square yards of crystal clear film, enough for five standard three-by-five-foot windows.

Best for single-season sealing on smooth frames

This kit suits anyone who wants a simple, one-time installation to block air leaks in both directions and cut condensation on existing windows. Renters or owners needing a reusable system, or those with textured frames that resist tape adhesion, should consider alternative methods.

Double-sided tape and clear film included

The supplied double-sided tape is formulated to hold the plastic film securely for the entire season without residue concerns. The crystal clear film maintains outward visibility while creating an insulating air pocket that reduces frost buildup and heat loss.
