Pemko 90100CNB-36 – Frequently Asked Questions

1) Will a nylon brush door sweep seal a door that has an uneven or out-of-level floor?
A brush sweep is the right pick when the floor is uneven. The Pemko 90100 uses compressed nylon filaments standing 1 inch below a 1-1/4 inch overall profile, so the bristles bend to follow high spots and dips instead of dragging or lifting off the floor the way a solid vinyl or neoprene blade does. If the floor is flat and you want a tighter air seal, a blade-type sweep like the NGP 197NA with a neoprene insert or the NGP 101V with a vinyl insert is the better match.
2) Can I use the Pemko 90100 door sweep on a fire rated door?
Yes. The 90100 sweep is BHMA Certified, Fire Rated to UL10C Positive Pressure, smoke tested to UL1784, and cUL Listed 4L10. That covers the two things a facility inspector looks for on a rated opening: the positive pressure fire rating and the smoke test. It is also GREENGUARD Gold Certified, which matters if you are chasing indoor air quality credits on a school or healthcare job.
3) How much floor gap will a 1 inch nylon brush sweep close?
The brush hangs 1 inch below the retainer with a 1-1/4 inch overall height, so it will cover an undercut in that range while still compressing. The retainer mounts with slotted holes, so you set the height at install and slide it up or down afterward to get the bristles just touching the floor. Set it so the brush wipes the floor rather than crushing into it, or you add drag to the closer.
4) I need a door sweep that seals against water and drafts, not just dust. Is a brush sweep the right choice or should I use a blade?
A brush sweep like the Pemko 90100 uses compressed nylon filaments that ride over uneven floors and thresholds, which is why it is used against dust, drafts, air, wind, insects, smoke and water. Where you want a continuous contact seal instead of filaments, the blade-insert sweeps are the alternative: the NGP 101V uses a vinyl insert in an aluminum alloy housing, the NGP 197NA uses neoprene in an anodized aluminum housing, and the Cal-Royal BTN-112 uses a neoprene insert in an extruded aluminum retainer. Blade sweeps wipe a flat, clean floor; brush sweeps tolerate rough or irregular surfaces.
5) What door sweep should I use on a boiler room or kitchen door where temperatures run high?
The Pemko 90100 nylon brush stays flexible down to -40 F and its filaments have a melting point above 400 F. If the opening runs beyond that band, the NGP 200SA is a silicone door sweep in an anodized aluminum housing rated for a temperature range of -100 F to 500 F. Silicone gives you the wider service range; the nylon brush gives you a filament seal that tolerates an uneven floor.
6) Will a nylon brush sweep hold up in an unheated warehouse or a freezer corridor?
The nylon filaments stay flexible down to -40F and the material's melting point is above 400F, so cold storage vestibules, loading dock doors and unconditioned warehouse openings are within range. If your application runs colder or hotter than that, the NGP 200SA silicone sweep is rated -100F to 500F.
7) Will this stop mice and insects from getting under an exterior door?
That is one of the main reasons this brush gets specified. The compressed nylon filaments close the undercut against dust, drafts, wind, insects and water, and the nylon naturally repels rodents and spiders rather than giving them something soft to chew. On a rated opening it also carries the UL1784 smoke test, so the same sweep does pest control and smoke sealing at once.
8) Which door sweep hides the mounting screws?
The Pemko 90100 mounts to the bottom of the door, so the casing sits under the door face and the fasteners are not exposed on the pull side; slotted holes let you adjust it to the floor after it is hung, and the design permits use as a concealed seal in many applications. The face-applied alternatives in the same family - the NGP 101V vinyl sweep, the NGP 197NA neoprene sweep, and the Cal-Royal BTN-112 - carry their seal in an aluminum housing on the door face. If the appearance of the door face or screw tampering matters, that mounting difference is the deciding one.
9) Is the Cal-Royal BTN-112 a direct replacement for a Pemko 90100 brush sweep?
They are not the same seal. The Pemko 90100 carries a gray nylon brush insert in a 90 degree aluminum retainer; the Cal-Royal BTN-112 carries a neoprene insert in an extruded aluminum retainer. Swapping one for the other changes how the door bottom contacts the floor - filaments versus a neoprene blade - so on a fleet of doors where the existing sweeps are brush type, matching brush to brush keeps the sweep behavior and the look consistent across the openings.
10) Can I use a Pemko 90100 brush sweep on a sliding or overhead door, not just a swing door?
Yes. The 90100 is used on overhead, section, sliding and automatic doors as well as standard hollow metal and wood swing leaves. The design also permits it to be run as a concealed seal in many applications, so it is not limited to the face-mounted door bottom role.
11) How do I adjust a door sweep after it is installed if the door still drags or leaks?
The 90100 retainer is drilled with slotted holes, so you back the screws off part way, slide the retainer up or down, and retighten. No new holes, no removing the door. That is the practical difference on a fleet of openings where floors settle at different rates; you tune each door on a walk-through rather than re-drilling.
12) What is the plainest option if I just need to stop a draft under an office door with a smooth floor?
On a flat, smooth floor a blade sweep is the simple answer: the NGP 101V is a vinyl door sweep in an aluminum alloy housing, and the NGP 197NA is a neoprene sweep in an anodized aluminum housing. Choose the Pemko 90100 nylon brush instead when the floor is carpeted, tiled with grout lines, or otherwise uneven, since compressed filaments follow a surface a solid blade drags on, and when you want the certifications the 90100 carries.
