Bottom-Mount Weatherstripping


Bulb Weatherstripping Seal	Vinyl Plastic Flat Weatherstripping Seal

Neoprene/Neoprene Foam Flat Weatherstripping Seal	Finned Weatherstripping Seal

Brush Weatherstripping Seal

Also known as door sweeps, this weatherstripping closes the gap between the bottom of the door and the floor.

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

Finned Weatherstripping Seal—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 Weatherstripping Seal—Brush seals have flexible bristles that fill the gaps in irregular surfaces, such as pitted concrete, to block light, wind, 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 Plastic Seal—Vinyl is flexible, durable, and moisture resistant.

SBR Seal—SBR resists moisture and abrasion. It’s often used for seals on high-traffic doors, since it won’t break down from dragging on rough surfaces. Unlike neoprene, it's not oil resistant.

Neoprene Seal—Neoprene is more weather resistant than SBR and vinyl. It also stands up to water, oil, and detergents.

Anodized Aluminum—Seals with an anodized aluminum flange are more corrosion resistant than seals with an aluminum flange. The finish won’t tarnish even in harsh weather conditions.

Stainless Steel—Seals with a stainless steel flange are stronger than seals with an aluminum flange. They’re also more chemical and corrosion resistant.

UL 1784—Seals that meet UL 1784 are rated for smoke and draft control.

Wraparound Bottom-Mount Weatherstripping


Flat Weatherstripping Seal Shown Installed	Vinyl Plastic Bulb Weatherstripping Seal	Neoprene Flat Weatherstripping Seal

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

Bulb Weatherstripping Seal—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.

Flat Weatherstripping Seal—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.

Vinyl Plastic Seal—Vinyl is flexible, durable, and moisture resistant.

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

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

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

3" Flange Height—Similar to a kick plate, weatherstripping with a 3" high flange protects the base of the door from damage.

Half-Mortise Self-Adjusting Bottom-Mount Weatherstripping

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 silicone or neoprene seal. Up to 2" can be removed from weatherstripping with a santoprene seal.

Adhesive-Back Bottom-Mount Weatherstripping

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.
