Stop rain and snow from pooling in your threshold and seeping under the door. This weatherstripping has a drip guard that diverts water away from the seal between the bottom of the door and the floor. Also known as door sweeps.

Bulb seals compress against the floor or threshold to form a tight seal, and they conform to uneven surfaces. They insulate doors better than flat, finned, and brush seals.

Flat seals press tight against smooth surfaces, forming a solid barrier that blocks insects, drafts, and precipitation. However, they don’t compensate for uneven surfaces as well as bulb, finned, or brush seals.

Finned seals have three layers that press against the floor to create three separate barriers. They look similar to flat seals, but they’re better at insulating uneven surfaces.

Brush seals have flexible bristles that fill the gaps in irregular surfaces, such as pitted concrete, to block light, drafts, and moisture. Made of nylon, the bristles are durable and long-lasting. They’re also lightweight, so they won’t slow down self-closing doors.

Vinyl is flexible, durable, and moisture resistant.

Stick on this weatherstripping to seal the gap beneath your door, blocking out drafts, noise, moisture, dust, and insects. Three fins create multiple sealing points against the floor or threshold to compensate for uneven surfaces and insulate better than flat seals. Made of vinyl, this weatherstripping is flexible, rugged, and moisture resistant to withstand wear and tear. A 3M VHB (Very High Bond) adhesive ensures it will stay attached to your frame in any weather, no drilling or hardware required. For a precise fit, cut it to length with a hacksaw. It’s also known as a door sweep.

Avoid scuffing your floor and reduce wear on your seals—this weatherstripping has a plunger that lowers the seal as the door is closed and raises it as the door is opened. Also known as door sweeps, they close the gap between the bottom of the door and the floor. Weatherstripping can be cut with a saw. Up to 12" can be removed from weatherstripping with a vinyl seal. Up to 4" can be removed from weatherstripping with a nylon, silicone, or neoprene seal.

Brush seals have flexible filaments that conform to fill gaps. The filaments are nylon for good wear resistance.

Bulb seals compress to form a tight seal and can compensate for uneven surfaces. Made of silicone, they resist heat and UV rays.

Flat seals press against surfaces to create a seal.

Vinyl seals are the most economical choice. Neoprene seals resist abrasion.

Closed seal projection is measured when the door is closed. It does not include how much the seal retracts when the door is open.

In addition to mounting to the door's face, this weatherstripping fits into cutouts (mortises) to mount flush with the door. It has a plunger that lowers the seal as the door is closed and raises it as the door is opened to avoid scuffing your floor and reduce wear on your seals. Also known as door sweeps, they close the gap between the bottom of the door and the floor. Weatherstripping can be cut with a saw. Up to 4" can be removed from weatherstripping with a neoprene seal. Up to 2" can be removed from weatherstripping with a santoprene seal.

Neoprene seals resist abrasion.

Santoprene seals resist abrasion and weather.

Seal drafts, dust, and insects out of your space—this weatherstripping hugs the bottom of your door. Also known as door sweeps.

Bulb seals compress against the floor or threshold to form a tight seal, and they conform to uneven surfaces. They insulate doors better than flat seals. Similar to a kick plate, weatherstripping with a 3" high flange protects the base of the door from damage.

Flat seals press tight against smooth surfaces to form a solid barrier. However, they don’t compensate for uneven surfaces as well as bulb seals. Behind the seal, there’s a fire-stop strip that expands to eight times its original size in temperatures above 375° F. During a fire, it completely fills any gaps. This weatherstripping is often added to existing fire doors to help them meet NFPA safety regulations without replacing the entire door. Use end plates to cover the sides of the doors for a finished look from every angle.

Neoprene is more weather resistant than vinyl. It stands up to abrasion, water, oil, and detergents.

Vinyl is flexible, durable, and moisture resistant.

Anodized aluminum is more corrosion resistant than plain aluminum. The finish won’t tarnish even in harsh weather conditions.

Stainless steel is stronger than aluminum, so it holds its shape better if exposed to fire. It’s also more chemical and corrosion resistant.

A drip guard diverts rain and snow away from the bottom of the door. Also known as door sweeps, this weatherstripping closes the gap between the bottom of the door and the floor.
