Door Bottom Seal Strip — Silicon Rubber Under-Door Weatherstripping for Drafts, Dust & Noise The gap at the bottom of a wooden door is one of the most common sources of cold drafts, dust infiltration, and noise bleed between rooms. This door bottom seal strip presses into or mounts along the door bottom edge to close that gap—without tools, adhesive, or permanent modification to the door. Made from silicon rubber, the strip is available in three profiles—LQ6, LQ7, and LQ17 (thickened)—each suited to different door bottom gap sizes and door types. Five color options (black, gray, transparent, brown, white) allow the strip to blend with the door finish. Each unit is 1 meter (39") in length and can be cut to size. Use it to seal the bottom of interior bedroom, living room, or bathroom doors against drafts and noise, block dust and insects under exterior or garage doors, or upgrade an old wooden door where the original bottom seal has worn out or was never installed. ✅ Compatible with standard wooden interior and exterior doors — LQ6 and LQ7 for standard gaps, LQ17 thickened for larger gaps or heavier doors — 1 m per unit, cuttable to length ✅ Key Features of This Door Bottom Seal Strip 🧲 Silicon Rubber Construction: Soft, elastic silicon rubber compresses against the floor on door closing and rebounds to shape when opened—maintains a consistent seal through years of daily use without hardening or cracking. 🔳 Three Profile Options (LQ6 / LQ7 / LQ17): LQ6 and LQ7 suit standard door bottom gaps; LQ17 is a thickened profile for larger gaps or doors that require a more substantial seal. Select the profile that matches your door bottom clearance. 🎨 Five Color Options: Black, gray, transparent, brown, and white—match the strip to your door color for a clean, unobtrusive finish on any door style. 🌡️ Draft & Thermal Insulation: Seals the under-door gap that allows conditioned air to escape and outside air to enter—reduces heating and cooling load and helps maintain room temperature. 🔇 Noise & Dust Reduction: The silicon body fills the gap that transmits airborne noise and allows dust and insects to pass under the door—suitable for bedrooms, home offices, and any room requiring quieter, cleaner conditions. ✂️ Cuttable to Length: Trim to any width up to 1 meter with scissors or a utility knife for a precise fit on narrower doors—no leftover bulk or bunching at the edges. 🎯 Who Is This For? 🛌 Bedroom & Living Room Doors Block cold drafts and reduce noise from hallways or adjacent rooms—install in minutes without tools and remove cleanly when no longer needed. 🏚️ Exterior & Garage Doors Seal the gap under exterior and garage doors to keep out dust, insects, and outside air—the LQ17 thickened profile handles larger gaps common on older exterior door frames. 🛁 Bathroom & Utility Doors Retain heat in bathrooms and reduce sound transfer from utility rooms—the silicon rubber body is moisture-resistant and maintains its seal on tile and hardwood floors. Material Silicon rubber Profile Options LQ6 (standard), LQ7 (standard), LQ17 (thickened) Colors Available Black, Gray, Transparent, Brown, White Length per Unit 1 meter (39"), cuttable to shorter lengths Compatible Door Types Wooden interior and exterior doors Floor Compatibility Tile, hardwood, laminate, carpet Application Bedroom, living room, bathroom, exterior, garage doors Mounting Method Press-fit or surface mount (refer to profile instructions) ❓ Frequently Asked Questions What is the difference between LQ6, LQ7, and LQ17? LQ6 and LQ7 are standard-thickness profiles suited to typical interior door bottom gaps. LQ17 is a thickened profile designed for larger gaps or heavier doors where a more substantial seal is needed. Measure the gap between the bottom of your door and the floor when the door is closed to determine which profile is appropriate. How do I measure the right profile for my door gap? Close the door and slide a ruler or feeler gauge under the bottom edge to measure the gap height. For gaps up to approximately 8–10 mm, LQ6 or LQ7 will work. For gaps larger than 10 mm, choose the LQ17 thickened profile. When in doubt, size up—silicon rubber compresses to fill smaller gaps. Can I cut the strip to fit a narrower door? Yes. Cut to any length up to 1 meter using scissors or a utility knife. Measure your door width first and mark the strip before cutting. Cut at a straight 90° angle for a clean edge. Will the strip scratch hardwood or tile floors? No. The soft silicon rubber body glides over floor surfaces without scratching. It is suitable for hardwood, tile, laminate, and low-pile carpet. The strip moves with the door as it opens and closes without snagging or dragging. Is this strip suitable for exterior doors exposed to rain? Yes. Silicon rubber is waterproof and moisture-resistant. It will not absorb water, swell, or degrade from rain exposure. For exterior doors, ensure the strip makes full contact with the threshold or floor surface when the door is closed for the best weather seal. How do I install the door bottom seal strip? Measure and cut the strip to your door width. Depending on the profile, the strip either presses onto the door bottom edge or mounts to the door face with the included or separate adhesive. Close the door to verify the strip makes contact with the floor along its full length. Adjust the position if any gaps remain. 🛒 Select your profile, color, and length above, then add to cart.
