Pemko 3452AV 28 – Frequently Asked Questions

1) Brush or Eco-V insert on a Pemko 3452 door bottom, which should I order?
Two things to decide on the 3452: insert and finish. The nylon brush sweeps over uneven, dirty or carpeted thresholds and keeps sealing where a solid seal would drag or wear a flat spot, and the filaments naturally discourage rodents and spiders. The Eco-V insert is the solid-seal option and closes the gap tighter on a smooth, flat floor where air infiltration is the concern. Both are offered in every length and in all three finishes.
2) How much floor gap will a Pemko 3452 close?
The brush stands 3/8 inch tall below the retainer, and the retainer profile is 9/16 inch wide. So plan on it covering an undercut of roughly 3/8 inch or less once you set it with the slotted holes. If your door has a bigger gap than the brush can reach, you want a taller sweep or a threshold to raise the floor, not this one.
3) I have an old neoprene or vinyl sweep on the door. Can I put a Pemko 3452 in its place?
A surface-applied sweep like the 3452 screws to the face of the door at the bottom rail, so swapping out an existing surface sweep is a matter of the new one being long enough and the slotted holes letting you clear or reuse the old screw line. If you would rather stay with a solid seal, ZenSupply carries the NGP 197NA neoprene sweep and the NGP 101V vinyl sweep, both in aluminum housings. Go to the brush 3452 when the floor is rough or carpeted; stay with neoprene or vinyl on a smooth floor where you want a tighter air seal.
4) For a door that needs a solid wiper seal instead of a brush, what should I use in place of the Pemko 3452?
Use a vinyl or neoprene sweep. The NGP 101V is a vinyl door sweep in an aluminum alloy housing, and the NGP 197NA is a neoprene door sweep in an anodized aluminum housing. A solid vinyl or neoprene blade wipes a continuous line across a smooth floor or threshold, while the Pemko 3452 uses densely compressed nylon filaments that conform to irregular surfaces. The Cal-Royal BTN-112 also pairs a neoprene insert with an extruded aluminum retainer if you want the wiper style in that brand.
5) Will a nylon brush door sweep still seal in freezing weather?
The nylon brush on the 3452 stays flexible down to -40F and does not melt below 400F, so it will not stiffen up and stop sweeping on a January exterior door the way some seals do. That temperature range is the reason this one shows up on loading dock and exterior entry doors in cold climates.
6) What finishes does the Pemko 3452 come in for matching existing doors?
Three: mill finish aluminum, clear anodized aluminum and dark bronze anodized aluminum. Clear anodized is the usual match for aluminum storefront and clear anodized frames, dark bronze for bronze-anodized entrances, and mill finish is the economical choice where the sweep is on a painted hollow metal door or out of sight. Every finish is available in all six stock lengths with either insert.
7) Does the Pemko 3452 door bottom meet green building requirements for a school or healthcare project?
The 3452 is GREENGUARD Gold Certified, which is the low-emissions certification specified on school and healthcare interiors, and it is BHMA certified as well. It is a commercial-grade product, aluminum retainer with a nylon insert, so it fits institutional standardization across a facility rather than a residential spec.
8) Which door sweep handles a wider temperature swing than the Pemko 3452?
The NGP 200SA silicone door sweep is rated for a temperature range of -100 F to 500 F. The Pemko 3452 brush stays flexible down to -40 F with a melting point above 400 F. For a boiler room, a commercial kitchen line, or an unheated exterior opening in a severe climate, the silicone sweep covers a broader band; for standard commercial entrances, storefronts, and stairwells, the 3452 range is well inside normal service conditions.
9) Is the Cal-Royal BTN-112 the same thing as a Pemko 3452?
They look alike on the shelf and differ where it matters. Both mount an insert in an aluminum retainer along the door bottom, but the Cal-Royal BTN-112 carries a neoprene insert, while the Pemko 3452 is supplied with either a nylon brush insert or an Eco-V insert. A neoprene blade and a nylon brush behave differently against the floor: the blade seals a consistent line on a flat surface, the brush rides over thresholds, carpet transitions, and floor debris. Match the insert type to the floor condition rather than to the housing.
10) We are standardizing door sweeps across a portfolio in bronze - which options carry an anodized finish?
The Pemko 3452 is available in mill finish aluminum, clear anodized aluminum, and dark bronze anodized aluminum, so a bronze standard can run across the fleet in one part number family with either the nylon brush or Eco-V insert. Among the alternatives, the NGP 197NA neoprene sweep and NGP 200SA silicone sweep both use anodized aluminum housings, while the NGP 101V uses an aluminum alloy housing. If the goal is one visual standard across every opening, the 3452 finish range plus its two insert options covers both smooth and rough floor conditions without changing the look of the door bottom.
11) Which door sweep should I use on a door that sees extreme heat, like a boiler room or kitchen?
The 3452 brush holds up to above 400F before the nylon melts, which covers most commercial service doors. If the opening runs hotter or colder than that, the NGP 200SA silicone sweep is rated -100F to 500F and is the better pick. For an ordinary exterior entrance the 3452 range is more than the door will ever see.
12) How many Pemko 3452 sweeps do I need for a pair of doors?
One per leaf. Each 3452 is a single surface-applied door bottom mounted to the face of one door, so a pair of 36 inch leaves takes two 36 inch pieces. Order the same insert and finish on both so the pair matches and both leaves seal the same way at the floor.
