- Front door that needs a permanent, snug seal: KS Hardware Double Bubble because the adjustable mechanism and drip cap deliver a tight, durable entryway seal.
Frequently Asked Questions
Will weatherstripping stick to painted wood or metal?
Most adhesive silicone strips and tapes will adhere to painted wood or metal, but the surface must be clean, dry and smooth. Wipe the area with rubbing alcohol, let it dry, and warm the adhesive with a hairdryer in cold conditions to improve bonding.
Which style is best for an exterior entry door?
For exterior entry doors, a screw-on or adjustable sweep (like an adjustable double-bubble) provides the most reliable, long-term seal against drafts, moisture and pests. Peeland-stick strips can work but are less secure under heavy use.
How do I choose the right thickness or profile?
Match the strip thickness and profile to the measured gap: thin adhesive strips and T-shaped seals suit narrow gaps (under 1"), while thicker 2mm-plus strips, double-bulb or slide-on sweeps handle larger gaps and offer better durability.
