NGP 5070B-36 – Frequently Asked Questions

1) Will the NGP 5070 smoke seal work on a fire-rated door assembly?
The 5070 silicone double shark fin seal is BHMA certified to ANSI/BHMA A156.22 for heat, cold, air infiltration and smoke infiltration, which is the performance standard smoke and draft control gasketing is tested against. It is used on commercial fire door assemblies, healthcare smoke barriers, and high-rise smoke control openings. Note that the gasketing carries the A156.22 certification on its own performance; the door and frame assembly's fire rating comes from its own listing.
2) What size gap will a 1/2 inch by 5/16 inch shark fin smoke seal close?
The 5070 profile measures 1/2 by 5/16 inches, so it mounts on a 1/2 inch wide flat surface (the frame stop or door face) and the fins stand 5/16 inch proud before compression. Two fins rather than one means it seals across a wider range of door-to-frame clearance than a single fin gasket, and the silicone has memory so it recovers each time the door swings.
3) How much NGP 5070 do I need to gasket a single door opening?
For a standard 3-0 by 7-0 opening you gasket both jambs and the head, so roughly 84 inches per jamb plus 36 inches across the head. The 5070 comes in 36, 48, 72, 84, 96 and 108 inch lengths, so a typical single door takes two 84 inch pieces and one 36 inch piece. Buy the jamb lengths long and trim rather than splicing, since every joint is a leak path for smoke.
4) Does the NGP 5070 smoke seal need screws, or is it adhesive-backed?
No fasteners and no drilling. The 5070 uses a modified acrylic pressure sensitive adhesive with a release liner, so you peel and stick it to the stop. The adhesive is specified for high initial adhesion and permanent mounting, which means you get one shot at placement, so dry-fit the length first. It is rated for exterior as well as interior locations.
5) Can I use a silicone smoke seal in a room with an FM200 or Halon fire suppression system?
Yes, the 5070 is specifically recommended for areas using FM200 or Halon suppression systems. Those systems only work if the enclosure holds the agent concentration, so perimeter leakage at the door is what fails a room integrity test. The silicone double fin seals the head and jambs against that leakage and holds up to the temperature swing, rated -100 F to 500 F.
6) What is the difference between the NGP 5070 shark fin smoke seal and Cal-Royal PG-601 perimeter gasketing?
They seal the same perimeter two different ways. The NGP 5070 is a self-adhesive silicone double shark fin seal, 1/2 inch wide by 5/16 inch tall, with a modified acrylic pressure sensitive adhesive and release liner that sticks directly to the stop face, and it holds flexibility from -100 F to 500 F with BHMA certification to ANSI/BHMA A156.22 for heat, cold, air infiltration and smoke infiltration. The Cal-Royal PG-601 is aluminum channel perimeter gasketing with a vinyl insert, so it mounts as a rigid retainer channel fastened to the frame and carries a replaceable vinyl seal. Choose the 5070 when you want a peel-and-stick seal on an existing frame with no fastening into the stop, and the PG-601 when you want a fastened aluminum retainer with a serviceable insert.
7) Can Cal-Royal PG-601 gasketing be used in place of an NGP 5070 silicone smoke seal on a fire door?
Treat them as separate specifications rather than drop-in equivalents. The NGP 5070 is the silicone double shark fin seal carrying BHMA certification to ANSI/BHMA A156.22 for heat, cold, air infiltration and smoke infiltration, and its siloxane compound is rated -100 F to 500 F, which is the basis on which it is recommended for commercial fire door assemblies, healthcare smoke barriers and areas served by FM200 or Halon suppression systems. The Cal-Royal PG-601 is aluminum channel gasketing with a vinyl insert, a different material and a different mounting method. If your smoke barrier drawing calls out a silicone seal to A156.22, substitute against that callout, not against the profile shape.
8) Which is better for a retrofit, adhesive silicone smoke seal or aluminum channel perimeter gasketing?
Adhesive silicone like the 5070 goes on an existing frame with no machining, so it is the faster retrofit and the one that suits an occupied building. Aluminum channel gasketing, such as the Cal-Royal PG-601 with a vinyl insert, screws to the frame and gives you a rigid carrier with a replaceable insert, which is worth it on high-traffic openings where the seal gets abused and you want to swap the insert rather than re-gasket. Channel type also holds a straighter line on a frame that is not clean or flat.
9) Will an unheated warehouse or exterior door freeze this gasket stiff in winter?
No. The siloxane synthetic rubber stays flexible from -100 F to 500 F, so it keeps its seal in an unconditioned loading dock or a mechanical room that runs hot. That range is the practical reason to pay for silicone over vinyl on exterior and unconditioned openings, since vinyl stiffens in the cold and takes a set.
10) Which perimeter seal should I use if I cannot fasten into the door frame?
Use the NGP 5070 silicone double shark fin seal. It mounts with a modified acrylic pressure sensitive adhesive with release liner that gives high initial adhesion and long-term holding power for permanent mounting in interior and exterior locations, so it goes onto an existing frame with no drilling and no retainer. The Cal-Royal PG-601 is aluminum channel gasketing with a vinyl insert, a retainer-and-insert design. On hollow metal or aluminum frames you do not want to drill, and on occupied buildings where you are sealing openings without taking the frame out of service, the adhesive-mounted 5070 is the one that fits the constraint.
11) If a seal gets damaged in service, is the NGP 5070 or the Cal-Royal PG-601 easier to service?
They fail and get repaired differently. The Cal-Royal PG-601 uses an aluminum channel with a vinyl insert, so the channel stays fastened and the insert is what gets pulled and replaced. The NGP 5070 is a self-adhesive silicone seal with a modified acrylic pressure sensitive adhesive intended for permanent mounting, so a damaged run is stripped and a fresh length applied; it comes in brown and clear in 36, 48, 72, 84, 96 and 108 inch rolls, so you can cut a replacement leg without redoing the whole opening. For a facility standardizing across many doors, that roll range is what determines how much stock you keep on the shelf for repairs.
12) Does the NGP 5070 come in a color that will not show on a painted or aluminum frame?
Two finishes: clear and brown. Clear disappears on light or anodized aluminum frames and on glass front entries; brown blends on dark bronze, wood, and painted dark frames. Both are offered in every length, from 36 through 108 inches.
13) Will a silicone smoke seal survive washdown, cleaning chemicals, and UV on an exterior door?
The 5070 silicone resists ozone, UV, aging, weathering, water, detergent, alcohol and chemical exposure, so it holds up on exterior openings and in facilities where doors get wiped down with disinfectant, like healthcare corridors. That resistance is a property of the silicone itself, not a coating that wears off.
14) Is the NGP 5070 smoke seal a commercial product or is it residential weatherstripping?
Commercial. The 5070 is specified for fire door assemblies, institutional smoke barriers, and code compliance work in government, healthcare, and education buildings, and it is certified to ANSI/BHMA A156.22, the commercial door gasketing standard. It will physically work on a residential door, but you are paying for certified smoke performance you would not need there.
15) Can I stock NGP 5070 smoke seal on the shelf, or does the adhesive go bad?
The adhesive has a one-year shelf life when properly stored, so this is not a part to buy deep and sit on. Order to the job for a retrofit run, and rotate stock if you keep the 84 and 96 inch lengths on the truck for service calls.
