Adhesive-Back Frame-Mount Weatherstripping
No need to drill mounting holes, this weatherstripping has a peel-and-stick adhesive backing. Mount it to the sides and top of a door or window frame to seal gaps. The adhesive is made of acrylic for a waterproof and weatherproof bond.
Flat seals are made of a graphite/rubber blend, which expands by as much as 10 times their original thickness in extreme heat to completely seal out flames. Also known as intumescent seals, they’re commonly used in fire doors, which often have a built-in groove shaped to fit them.
Wraparound Bottom-Mount Weatherstripping
Seal drafts, dust, and insects out of your space—this weatherstripping hugs the bottom of your door. Also known as door sweeps.
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.
Stainless steel is stronger than aluminum, so it holds its shape better if exposed to fire. It’s also more chemical and corrosion resistant.

Fire-Stop Putty
Hand-mold this putty to fill small openings in fire-resistant walls and floors. It expands when heated and forms an insulating char that fills gaps left by melted pipes.
The pad is commonly used to seal openings around electrical boxes.
Paintable Fire-Stop Caulk
Seal small openings in fire-resistant walls and floors. Dispense cartridges using a caulk gun.
Expanding caulk expands when heated to fill voids left by melted pipes.

Fire-Stop Pipe Collars
Slide these into the small gaps around pipes passing through fire-resistant walls and floors. Collars have a sealant that expands when heated to fill gaps left by melted pipes.
Fire-Stop Sheets
Cut these sheets to any size and shape you need to seal large openings in fire-resistant walls and floors. They’re often used to fill the space around pipes, conduit, and ducts. These sheets are tested to ASTM and UL standards for stopping the spread of smoke and flames. Made of steel, they have a firestop coating that expands when it’s heated. If the equipment passing through these panels melts or shrinks during a fire, this coating will fill the gaps.
Use shears to cut these panels to size, then fasten to your surface with No. 10 self-drilling sheet metal screws (not included). Fill any gaps around the sheet with fire-stop caulk (sold separately) for a tight seal. Once they’re installed, you can paint over them without losing fire protection.
Fire-Stop Plugs
Squeeze plugs into small openings in fire-resistant walls and floors. They are reconfigurable, making them useful for applications where cable configurations change frequently. Plugs expand when heated to fill gaps left by melted cable.
Fire-Stop Bags
Stack these bags to fill large gaps in fire-resistant walls and floors. They are reconfigurable, making them useful for applications where cable configurations change frequently. Bags expand when heated to fill gaps left by melted cables.
