What the AI looks for in Weatherproofing Products
- Find the leak before buying
- On a windy day, hold an incense stick or a damp hand around doors, windows and penetrations. Close doors and sashes on a sheet of paper; if it slides out freely, the seal there is not making contact. Most drafts come from a few specific gaps, and the right product depends on whether the gap is at a moving joint, a fixed joint or a pipe.
- Moving joint vs fixed joint
- Use weather stripping, sweeps and door seals where parts move. Use caulk on fixed cracks such as trim-to-wall and frame-to-siding. Caulk tears on moving parts, and foam tape fails as a filler for static cracks.
- Material for the conditions
- Prefer EPDM rubber, silicone or vinyl-jacketed foam for exterior and high-use joints. Treat open-cell foam and felt as short-lived, low-cost fixes. Cheap foams take a compression set and crumble, often within a season on a heavily used door.
- Reversibility
- For rentals or seasonal use, choose removable products such as shrink film kits, removable caulk and tension sweeps. Permanent adhesives and screw-on seals can damage finishes or break lease terms.
Brands that matter
- Frost King: Broad budget range covering tapes, V-strip, sweeps, pipe foam and window kits.
- M-D Building Products: Broad range, including sturdier aluminum-and-vinyl door seals and thresholds.
- 3M: Best-known indoor window shrink-film kits.
- Duck: Window film kits and weatherproofing tapes.
What to avoid
- Sealing combustion-air or dryer-vent openings in an effort to stop drafts.
- Using indoor foam tape on exterior or sun-exposed joints.
