NGP 161SDKB-36 – Frequently Asked Questions

1) How many pieces of the NGP 161SDKB perimeter seal do I need for one door opening?
The 161SDKB comes in two lengths, 36 inches and 84 inches. A standard single opening takes one 36 inch piece across the head and two 84 inch pieces down the jambs, so order three pieces per door. A pair of doors needs the same jamb quantity plus enough head stock to span both leaves.
2) Is the NGP 161SDKB perimeter seal rated for smoke on a fire-rated door assembly?
It is BHMA certified to ANSI/BHMA A156.22, with performance testing covering heat, cold, air infiltration and smoke infiltration. That is the standard a smoke-rated door assembly gets specified against, and the seal is called out for use on fire-rated door assemblies.
3) What is the difference between the NGP 161SDKB perimeter seal and the Cal-Royal PG-601 perimeter gasketing?
Both are aluminum channel perimeter gasketing for door frames, but the sealing element differs. The NGP 161SDKB uses a synthetic rubber polymer siloxane (silicone) gasket in an aluminum alloy 6063 T5 temper channel, rated from -100 F to 500 F and BHMA 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 or smoke-rated assembly, or the seal must hold up to extreme heat, the silicone gasket of the 161SDKB is the one that carries those certified ratings.
4) Can vinyl perimeter gasketing be used instead of silicone on a door protected by an FM200 or Halon suppression system?
The NGP 161SDKB is the seal specifically recommended for areas using FM200 or Halon fire suppression systems, because its siloxane gasket is flame resistant and holds flexibility and memory from -100 F to 500 F. The Cal-Royal PG-601 is a comparable aluminum channel perimeter gasketing but uses a vinyl insert, a different gasket material. For suppression-system rooms where the silicone recommendation is written into the spec, specify the 161SDKB.
5) Will this door seal hold up on an exterior opening in a cold climate?
The silicone gasket runs from -100 F to 500 F and keeps its flexibility and memory through that range, so it will not go stiff and stop sealing in winter. The gasket is also rated for ozone, UV and aging resistance and is moisture resistant, which is what matters on an exterior jamb.
6) Do I need to buy fasteners separately for the NGP 161SDKB perimeter seal?
No. #6 x 3/4 inch stainless steel sheet metal screws ship with the seal. The screw holes are slotted, so you can shift the housing in or out against the door face to dial in gasket compression before you snug the screws down.
7) Can I use this seal in a room protected by an FM200 or Halon clean agent system?
Yes, the 161SDKB is recommended for rooms using FM200 or Halon suppression. Those systems depend on the enclosure holding agent concentration, which is why a tested perimeter seal on the door is part of the room integrity package.
8) I need perimeter gasketing for an interior office door that is not fire rated. Is there a simpler option than the NGP 161SDKB?
Yes. For a non-rated interior door where you mainly want to cut light, dust and sound transfer, the Cal-Royal PG-601 aluminum channel perimeter gasketing with a vinyl insert covers that duty. The NGP 161SDKB brings the extras you would be paying for on a rated opening: silicone gasket certified to ANSI/BHMA A156.22 for smoke and air infiltration, a -100 F to 500 F range, and resistance to ozone, UV and aging. Both mount in the frame rabbet as an aluminum channel.
9) Will a door shoe work in place of the NGP 161SDKB perimeter seal?
No, they solve different sides of the opening. The NGP 161SDKB mounts to the frame head and jambs and seals the perimeter gap around the door edge with a silicone gasket, using slotted screw holes so the channel can be adjusted in for contact. A door shoe attaches to the bottom of the door itself to seal against the threshold or sill. Cal-Royal catalogs the PG-601 perimeter gasketing within its Door Shoes Series, so the series name alone does not tell you which part you are getting; confirm you are ordering perimeter gasketing for the frame and a separate bottom seal for the door.
10) For an exterior door exposed to sun and weather, does the NGP 161SDKB hold up better than vinyl-insert gasketing?
The NGP 161SDKB is specified with excellent resistance to ozone, UV and aging, plus moisture-resistant properties, in a 6063 T5 aluminum channel, which is why it is called out for long-term exterior as well as interior use. The Cal-Royal PG-601 uses a vinyl insert in an aluminum channel, a different gasket material. On a sun- and weather-exposed opening, the silicone gasket of the 161SDKB is the material carrying the published UV, ozone and aging resistance.
11) Will the dark bronze finish on this NGP seal match anodized bronze frames and hardware?
The housing is aluminum alloy 6063 T5 in a dark bronze finish, which is the usual companion to dark bronze anodized frames, thresholds and door bottoms. If you are standardizing openings across a building, all three perimeter pieces come in the same finish so the head and both jambs read as one run.
12) Is this perimeter gasketing suitable for high-traffic commercial doors, or is it a residential product?
It is a commercial product. The 6063 T5 aluminum housing and silicone gasket are specified for office buildings, healthcare, schools, government and industrial facilities, and there is a .07 aluminum version for military specifications where heavier housing is required.
