- Is 1-inch-thick foam too thick for a door gap?
- Usually yes for a standard interior door gap, which is closer to 1/8 to 1/4 inch. Use this where the gap is wide, such as an old garage door, hatch or uneven frame, or compress it and trim as needed.
- Will the adhesive hold on an exterior door?
- It holds best on clean, dry, smooth surfaces. On exterior doors, heat and moisture can loosen it over time, so clean the surface with alcohol first and press firmly for a full minute.
- Can I cut it to size?
- Yes. A sharp utility knife or heavy scissors cuts it cleanly. Cut slightly long and compress it into the gap for a tighter seal.
- Does neoprene foam absorb water?
- No. Closed-cell neoprene resists water absorption, which makes it suitable for exterior gaps and damp areas, unlike open-cell foam.
- How much does 13 feet cover?
- It comes as two 6.5-foot rolls. That is enough for roughly one door frame plus a window, depending on the gap width and how much you trim.
- When is the price lowest?
- Weatherstripping tends to be discounted in fall and winter, when draft-proofing demand rises. The current $8.21 at Walmart as of November 4, 2026 is already near the low end for this size.
