    FAQs

    One 49‑ft pack typically covers 2–3 standard doors or multiple windows. A single door (sides + top) uses about 12–18 ft.

    With proper surface prep, indoor installs commonly last through a full heating/cooling season or longer. Outdoor exposure can reduce lifespan; periodic replacement may be needed on sun‑baked or high‑traffic thresholds.

    Best for small to medium gaps, roughly 1/16–3/8 inch (1–10 mm). For larger or uneven gaps, you can double-layer or combine with a conventional door sweep at the bottom.

    It can removes cleanly on clean, fully cured paint and sealed surfaces. Warm with a hair dryer and peel slowly at a low angle. Test delicate or fresh paint first.

    Painted wood, sealed wood, metal, vinyl/PVC, and smooth composites. Not recommended on dusty, oily, highly textured, or unsealed/crumbly surfaces. Clean with isopropyl alcohol, let dry fully, then apply.

    Yes. The continuous flap helps block drafts, water splashes, and common entry points for insects at the sill. For heavy wind‑driven rain, pair with a door sweep and proper threshold.

    Yes, but lifespan shortens with UV and weather. Apply above 50°F (10°C) to maximize bond.

    By closing air gaps, it helps cut street noise, dust, and pollen. It’s not a dedicated soundproofing product.
