Pemko 297AS 84 – Frequently Asked Questions

1) Will the Pemko 297AS perimeter gasketing work on a fire-rated door assembly?
Yes. The 297AS is Fire Rated to UL10C and Smoke Tested to UL1784, so it can go on a fire-rated opening where the assembly calls for smoke and draft control gasketing. It is also GREENGUARD Gold Certified, which matters if you are chasing indoor air quality credits on a school or healthcare job.
2) How much gap will a 1/4 inch perimeter seal close on a commercial door?
The 297AS has a 1/4 inch overall height on the aluminum base, with a profile height of 813/1000 inch, and it seals gaps up to the depth of the silicone seal. That suits a normally hung commercial door with a typical jamb clearance. If your frame is racked or the leaf has been planed and you are looking at a gap well past a quarter inch, a low-profile perimeter seal like this will not take it up and you want a deeper-bulb or adjustable jamb seal instead.
3) Does the Pemko 297AS come with fasteners or do I need to order screws separately?
Everything to hang it is in the box. The 297AS ships with self-adhesive tape and PHSMS #6 x 5/8 inch TEK screws, and the aluminum base is punched on 6 inch centers with slotted holes. The TEK screws mean you can drive straight into a hollow metal frame without pre-drilling, and the slots let you shift the piece for alignment before you tighten down.
4) How many pieces of Pemko 297AS do I need per door opening?
Perimeter gasketing goes on three sides of the frame, so a single opening takes one head piece plus two jamb pieces. For a 3070 door, that is typically a 36 inch piece across the head and two 84 inch pieces down the jambs, cut to fit. The 297AS does not seal the bottom of the door, so if you also need the threshold gap closed you will want a door bottom sweep or door shoe in addition to it.
5) Silicone or vinyl insert for door gasketing in a hot or sun-exposed opening?
Go silicone. The 297AS uses a silicone insert, which holds up to sunlight, weather, ozone, oxidization, water and flame, and is self-extinguishing and non-toxic. Vinyl inserts tend to harden and take a set in heat and UV, which is what causes the seal to stop touching the door after a couple of seasons. On an exterior or west-facing opening, or anywhere near heat, the silicone is the one that keeps its memory.
6) Is Pemko 297AS gasketing OK for a hospital or lab door that gets wiped down with disinfectant?
Yes, and that is one of the reasons to spec it. The silicone insert is impervious to fungus and mildew and stands up to frequent cleaning with disinfectants without deteriorating under normal exposure. Combined with the UL1784 smoke test rating, it is a common choice for infection-control and healthcare openings.
7) Will mill finish aluminum gasketing look out of place next to my existing door frames?
The 297AS is supplied in mill finish aluminum, a plain unpainted silver, on every length offered. On aluminum storefront or unpainted hollow metal it blends. Against dark bronze or painted frames it will read as a bright line around the opening, so if you are matching a fleet of doors that already have anodized or dark gasketing, take that into account before standardizing on it.
8) Is the Pemko 297AS meant for residential doors or commercial openings?
This is a commercial-duty product. The 297AS is built with an aluminum base and screw-applied on 6 inch centers, which is how gasketing survives high-traffic office, school, government and multi-tenant openings. It will physically install on a residential door, but the fire and smoke test ratings it carries are there for commercial assemblies, and a homeowner-grade foam or vinyl jamb seal is the lighter-duty alternative.
