Pemko 18100CNB-48 – Frequently Asked Questions

1) Can I use the Pemko 18100 door sweep on a fire-rated door?
Yes. The 18100 brush sweep is fire rated to UL10C positive pressure and smoke tested to UL1784, so it can go on a labeled fire door assembly. It is also BHMA certified and carries Underwriters Laboratory 4L10 listing. That combination is what an inspector looks for on a rated opening, and it's the main reason to specify this sweep over a plain unrated brush sweep.
2) What length Pemko 18100 sweep do I need for a 36 inch door?
Take the 36 inch stock length for a standard 3-0 door. The 18100 comes in 36, 48 and 84 inch lengths. The 48 inch covers wider single leaves, and the 84 inch piece is normally cut down for pairs or oversized openings. Aluminum retainer sweeps like this are routinely field cut to the exact door width, so order the next length up rather than under.
3) How much clearance under the door does a Pemko 18100 brush sweep close up?
The retainer plus brush stands 1-7/8 inches overall with a 1/4 inch wide profile, and the nylon brush insert itself is 1 inch. The brush is what bridges the undercut, so it takes up a bigger and less consistent gap than a solid neoprene or vinyl sweep will, and it keeps sweeping cleanly over carpet, thresholds and uneven floors. Mount height on the door face sets the final gap you close.
4) Brush sweep or a rubber door sweep, which should I use on a commercial door?
Go brush when the floor is carpet, tile with height changes, or an exterior slab where a rubber blade would drag, wear or bind. The 18100's nylon brush flexes over irregular surfaces and keeps sealing where a solid insert would be pushed out of contact. Choose a solid neoprene or vinyl insert instead when your priority is a tight weather or water seal on a flat, smooth threshold. For smoke and air infiltration on a rated interior opening, the 18100 is the one that carries UL1784 smoke testing.
5) Will the Pemko 18100 sweep match my dark bronze door hardware?
Two finishes are offered: clear anodized aluminum with a gray nylon brush, and dark bronze anodized aluminum with a black nylon brush. Both are available in all three lengths, 36, 48 and 84 inches. The bronze/black pairing is the one that disappears against dark anodized storefront and bronze hollow metal; clear anodized suits mill finish aluminum and 630 stainless openings.
6) Is the Pemko 18100 sweep OK to install in a school or hospital with indoor air quality requirements?
It is GREENGUARD Gold certified for low chemical emissions, which is the certification specified for schools and healthcare spaces. The retainer is aluminum and the insert is nylon, and the sweep is a commercial-duty product. On rated corridor doors in those buildings it also satisfies the fire and smoke side, being UL10C positive pressure rated and UL1784 smoke tested.
7) Can one Pemko 18100 sweep cover a pair of doors?
No. A door bottom sweep mounts to the face of a single leaf, so a pair needs two pieces, one per leaf. Order by the width of each leaf, not the total opening: two 36 inch pieces for a 6-0 pair, not a single 84 inch. The 84 inch length exists for oversized single leaves and for cutting multiple shorter pieces from one stick.
8) Does the Pemko 18100 replace a worn brush insert, or is it the whole sweep?
The 18100 is the complete assembly: the 180 degree aluminum retainer with the 1 inch nylon brush already in it. If your existing Pemko retainer is sound and only the brush is worn, the insert alone is the P38100 brush. Buying the 18100 gets you both, which is the right call when the aluminum retainer is bent, corroded or the screw holes are wallowed out.
9) Will a nylon brush sweep hold up on a high traffic exterior commercial door?
The retainer is anodized aluminum and the product is rated commercial, so it stands up to the cycle counts and the weather exposure that kill residential-grade sweeps. Nylon brush filaments are the wearing part and they hold their sweep across grit, snow and door drag better than a rubber blade, which tears and takes a set. When the brush eventually wears, the P38100 insert replaces without pulling the retainer off the door.
