Self-Adhesive Silicone Door Draft Stopper — 39" Under Door Seal (Fits Gaps up to 1.18")
Multifunctional Door Draft Stopper
This triple-fin door sweep doesn’t just block cold air—it also helps reduce noise, keeps dust and odors out, and deters insects from crawling under the door. Perfect for bedrooms, nurseries, offices, and any room where you want a quieter, cleaner environment.
Save Money & Energy
In winter and summer, sealing the bottom gap prevents A/C and heating leakage to improve your room’s cooling/heating efficiency. Lower drafts = lower utility bills.
Thickened Pure Silicone
Made from premium, high-resilience silicone that bends without deforming. Smooth surface glides over floors and won’t scratch wood, tile, laminate, marble, or vinyl.
Industrial-Grade Self-Adhesive
Backed with waterproof, high-strength tape for long-lasting hold. The internal multi-hole design enhances sound insulation while keeping the strip light and flexible.
Trim-to-Fit, Tool-Free Install
Cut to length and stick on in minutes—no screws or drilling. Works on interior/exterior doors, sliding glass doors, shower doors, basements, garages, and balconies.
