NGP 160SDKB 36 – Frequently Asked Questions

1) Will the NGP 160SDKB perimeter seal work on a fire-rated door assembly?
The 160SDKB is a perimeter seal certified to ANSI/BHMA A156.22 for heat, cold, air infiltration and smoke infiltration, and NGP lists fire-rated door assemblies among its applications. The gasket is a synthetic rubber polymer siloxane (silicone) that is flame resistant and holds its seal from -100 F to 500 F, which is why it gets used on openings where a smoke seal has to survive heat rather than melt back. For a labeled opening, match the seal to what the door label and the assembly's listing call for.
2) What lengths does the NGP 160SDKB perimeter seal come in, and how many pieces do I need for one door?
Five lengths are offered: 36, 48, 72, 84 and 96 inches. A single door opening takes three pieces of perimeter gasketing, one for each jamb and one across the head, so a standard 3070 opening is usually covered by two 84 inch jamb pieces and one 36 inch head piece. Order per opening, not per door leaf, and remember a pair of doors still only needs two jambs and a head unless you are also sealing the meeting stile.
3) Do I get the mounting screws with the NGP 160SDKB, or do I have to buy fasteners separately?
Screws are furnished: #6 x 3/4 inch stainless steel sheet metal screws come with the seal. The holes in the aluminum retainer are slotted, so you can shift the gasket in or out against the door face after the screws are started and then snug them down. That adjustment matters on a door that is not hanging perfectly square, since it lets you tune compression jamb by jamb instead of accepting whatever the first hole line gives you.
4) Can I use the NGP 160SDKB in a room protected by an FM200 or Halon clean agent system?
Yes, and that is one of the applications NGP calls out for it. Clean agent suppression only works if the room holds concentration, which means the door perimeter has to be sealed tight enough to pass a room integrity test. The 160SDKB is recommended for FM200 and Halon spaces and is certified to ANSI/BHMA A156.22 for air infiltration. Seal the perimeter and the bottom of the door both; a perimeter seal alone leaves the largest gap in the opening open.
5) Does the NGP 160SDKB seal the bottom of the door too?
No. It is perimeter gasketing, meaning it mounts to the frame stop at the two jambs and the head. The gap under the door is a separate part, either a door bottom or sweep on the leaf or a threshold seal at the floor. If you are sealing an opening for smoke, weather or clean agent room integrity, budget for both; a perimeter seal on its own leaves the largest leak path in the opening wide open.
6) What is the difference between the NGP 160SDKB perimeter seal and the Cal-Royal PG-601 gasketing?
Both are aluminum channel perimeter seals that mount to the frame stop, but they differ in the gasket carried in the channel. The NGP 160SDKB uses a synthetic rubber polymer siloxane (silicone) gasket rated from -100 F to 500 F and certified to ANSI/BHMA A156.22 for heat, cold, air infiltration and smoke infiltration. The Cal-Royal PG-601 is an aluminum channel perimeter gasketing with a vinyl insert. If the opening is a fire-rated assembly or a smoke-rated door where the A156.22 heat and smoke infiltration performance has to be shown to an inspector, the 160SDKB is the one that carries that certification; for a plain weather and light seal on a non-rated interior or exterior door, the vinyl-insert PG-601 is a simpler channel seal.
7) Can Cal-Royal PG-601 gasketing be used on a door protected by an FM200 or Halon fire suppression system instead of NGP 160SDKB?
The NGP 160SDKB is the seal recommended for rooms served by FM200 or Halon fire suppression systems, because holding the room's agent concentration depends on the perimeter seal staying flexible and intact, and its siloxane gasket holds its flexibility and memory from -100 F to 500 F. The Cal-Royal PG-601 carries a vinyl insert in its aluminum channel, which is a general perimeter gasketing insert rather than a high-temperature elastomer. For a data room, clean agent room, or any enclosure where the suppression system's hold time is part of the design, specify the 160SDKB.
8) Is silicone gasketing worth it over a vinyl perimeter seal, or is vinyl good enough?
It depends on heat. The 160SDKB uses a siloxane silicone gasket rated -100 F to 500 F with good ozone, UV and aging resistance, which is what you want on an exterior opening in a hard climate, a mechanical or boiler room, or anywhere a smoke seal has to stay flexible when things get hot. For an ordinary interior office or corridor door where none of that applies, a vinyl-insert channel gasket like the Cal-Royal PG-601 does the same weather and light-seal job in an aluminum channel. Vinyl stiffens in deep cold and does not tolerate heat the way silicone does, so pick silicone where temperature swings are real.
9) Will the dark bronze NGP perimeter seal match dark bronze anodized frames and door hardware?
The 160SDKB carries a dark bronze finish on the aluminum retainer with a dense black silicone gasket, which is the combination specified to blend with dark bronze anodized aluminum frames and storefront. The retainer itself is 6063 T5 aluminum. On a fleet of openings where some frames are dark bronze and others are mill or clear anodized, expect to order two finishes rather than trying to make one work across both, since the retainer sits on the face of the stop where it is visible.
10) Is a door shoe the same thing as the NGP 160SDKB perimeter seal?
No, and they are not interchangeable. The NGP 160SDKB is a perimeter seal, meaning it mounts to the head and jambs of the frame and seals the crack between the door edge and the stop; a door shoe wraps the bottom edge of the door and seals against the threshold or sill. The Cal-Royal PG-601 is classed in a Door Shoes Series, and it is aluminum channel perimeter gasketing with a vinyl insert. A complete opening usually needs both: perimeter seal at head and jambs, and a shoe or sweep at the bottom. Ordering perimeter seal alone leaves the largest air path in the opening, the undercut, wide open.
11) What is the NGP 160SDKB perimeter seal actually made of, and will it hold up on an exterior door?
The retainer is 6063 T5 tempered aluminum alloy and the seal itself is a synthetic rubber polymer siloxane. That pairing is built for outdoor duty: the aluminum will not rust, and the silicone resists ozone, UV and aging and stays moisture resistant, so it keeps its memory and springs back against the door instead of taking a set after a few seasons of sun. It is a commercial-duty product, not a residential weatherstrip.
12) I have older NGP silicone perimeter seals on some doors. Will the 160SDKB match them?
Ordering the same 160S profile in the same dark bronze keeps a building's openings consistent, which is what matters when you are replacing a few damaged pieces across a floor rather than doing a whole opening. Compare the existing retainer to what you are ordering: look at whether the old piece is dark bronze or clear aluminum, and whether the insert is black silicone or a vinyl bulb. If the existing seal is vinyl, you are switching material as well as part, and the two will read differently at the joint.
