The Best Door Draft Stoppers and Window Insulation: 4 Compared (and One to Skip) · Home & Kitchen
Frost King Door or Window Double Draft Stop (DDS1)

The Best Window Insulation Kits: 4 Compared (and One to Skip) · Home & Kitchen
Frost King Economy Outdoor Plastic Storm Window Kit (P71A, 3 ft x 6 ft)
Plain plastic sheeting nailed over the outside of a wood window frame, a cheap but crude fix that newer indoor kits beat.
Why we skip it: It mounts with nails through fiber strips, so it suits wood frames only and leaves holes in exterior trim.
