Our take
The Duck MAX Strength kit is the go-to indoor window insulation film for cutting drafts and heat loss through single-pane and older windows. You tape the included double-sided tape around the window frame, press the clear film on, then shrink it tight and wrinkle-free with a regular hair dryer. The 5-window roll (62 in x 210 in) cuts to size for most standard windows, and the MAX Strength film is noticeably more puncture-resistant than Duck's standard kit, which helps in pet or kid households. It is a seasonal product: the film and tape are meant to be installed in fall and removed in spring, and removal can pull paint on older frames. For the money it is one of the most cost-effective ways to noticeably reduce cold drafts and condensation on problem windows.
What we like
- Dramatically cuts drafts and heat loss on old or single-pane windows for a low cost
- Shrinks nearly invisible with a hair dryer, so it does not block the view or much light
- MAX Strength film resists punctures better than standard kits, good for pets and kids
- Includes the mounting tape and enough film for up to 5 average windows
What to keep in mind
- Seasonal and essentially single-use; film and tape are discarded each spring
- Adhesive tape can lift paint or leave residue on older or freshly painted frames
- Needs a hair dryer and patience to get a wrinkle-free result on large windows
