NGP 5050B-17 – Frequently Asked Questions

1) Will the NGP 5050 silicone seal work on a 20-minute rated wood fire door?
Yes. The 5050 is certified under Edge Sealing System category "G" for 20-minute rated category B wood doors, covering single swing openings up to 4'0 x 8'0 and pairs up to 8'0 x 8'0. Beyond those leaf sizes the category G listing no longer applies, so an 8-foot-wide single leaf is outside what the seal is certified for.
2) Can I use the NGP 5050 seal on hollow metal fire doors as well as wood?
Both. The 5050 is listed for wood and hollow metal fire doors. On hollow metal it carries the smoke and draft control category "H" rating up to 3 hours, so it covers the smoke seal requirement on longer-rated metal openings, while the 20-minute category G listing is the one that applies to category B wood doors.
3) How much NGP 5050 gasketing do I need for one door opening?
A single 3'0 x 7'0 opening takes roughly 17 feet around the head and both jambs, which is why the 5050 comes in a 17-foot roll. Taller or paired openings step up to the 20, 21 and 25 foot rolls, and the 204 and 300 foot bulk rolls are how you buy it when you are gasketing a floor of doors or a whole building at once. The seal applies to the stop at the head jamb, latch jamb and hinge jamb.
4) How much clearance does the NGP 5050 seal take up on the door stop?
The seal section is 1/2 inch wide by 1/4 inch tall, so it sits 1/4 inch off the face of the stop and needs 1/2 inch of flat stop face to bond to. Check that the door leaf actually closes against a 1/4 inch standoff before you set it, since a tight-fitting leaf with almost no gap to the stop will bind on it.
5) Does the NGP 5050 need screws or does it just stick on?
No fasteners and no kerf. The 5050 mounts with a modified acrylic pressure sensitive adhesive under a release liner, so you peel and press it straight onto a clean door stop. That is the practical difference between it and a channel-mounted perimeter gasket like the Cal-Royal PG-601, which is an aluminum channel with a vinyl insert and has to be cut and fastened to the frame.
6) What temperature can silicone door gasketing take before it fails?
The silicone section of the 5050 runs from -100 F to 500 F and holds its flexibility and memory at both ends, which is why it is silicone and not vinyl. The adhesive is the limiting part: it is rated -30 F to 250 F. On a heated mechanical room, a boiler room door or an unconditioned exterior opening in a cold climate, the adhesive band is the number to design to, not the silicone band.
7) Is the NGP 5050 gasketing BHMA certified?
Yes, the 5050 is BHMA certified to ANSI/BHMA A156.22, tested for heat, cold and air infiltration performance. It is also RoHS directive compliant. For a hospital, school or government spec that calls out A156.22 gasketing by standard, that is the line item it satisfies.
8) Which color of NGP 5050 smoke seal should I order to match my frames?
Four colors are made: brown, charcoal, tan and white. Charcoal disappears on dark bronze and black frames, white on painted white or aluminum frames, and brown and tan on wood-tone and painted-frame work. Every color is offered in all six roll lengths, from 17 feet up to 300 feet, so you are not forced into a different length to get the color you want.
9) Can I use this seal in a room protected by an FM200 or Halon system?
That is one of the applications the 5050 is specifically recommended for. Clean agent systems only hold concentration if the enclosure is tight, and the silicone seal is called out for rooms using FM200 or Halon suppression. Data rooms, telecom closets and similar enclosures are where that matters.
10) Should I buy a 300 foot bulk roll of smoke seal or single-door rolls?
Buy the cut lengths (17, 20, 21 or 25 feet) when you are doing a handful of openings and want no waste and no field measuring. Go to the 204 or 300 foot rolls for a building-wide fire door program, where you are cutting many openings from one roll. One caution on stockpiling: the 5050 has a one year shelf life when properly stored, so a 300 foot roll bought for a job that slips does not keep indefinitely.
11) Will adhesive-backed smoke seal stay stuck long term or should I use a mechanically fastened gasket?
The 5050's adhesive is a modified acrylic pressure sensitive designed as a permanent mount, and it holds on a clean, dry stop within its -30 F to 250 F range. Where the frame face is dirty, heavily repainted, corroded, or exposed to temperatures outside that adhesive band, a mechanically attached perimeter gasket is the better call: the Cal-Royal PG-601 uses an aluminum channel with a vinyl insert that screws to the frame instead of relying on adhesion.
12) Will silicone smoke seal survive washdown and cleaning chemicals?
The 5050's siloxane silicone resists water, detergent, alcohol and chemical exposure, plus ozone, UV and general aging and weathering. That makes it workable on healthcare and food service openings that get wiped down with alcohol-based cleaners, and on exterior-facing frames where a vinyl seal would chalk and harden in sunlight.
13) Is the NGP 5050 seal meant for residential doors or commercial?
Commercial. The 5050 is a commercial-duty product aimed at rated openings in healthcare, education, government, industrial and multi-tenant residential buildings. On a house's interior doors there is no rated assembly for it to serve; it earns its place where a fire or smoke rating is being maintained.
