NGP 9550DKB-84 – Frequently Asked Questions

1) Will the NGP 9550 intumescent seal work on a 90-minute rated wood door?
Yes. The 9550 Edge intumescent system is rated for 20, 45, 60 and 90 minute category B wood doors, applied at the perimeter and at meeting edges. It is not a general purpose weatherstrip you add to any opening, the rating covers category B wood door assemblies specifically.
2) What is the largest door the NGP 9550 fire seal can be used on?
Single swing doors up to 4'0 x 9'0 and pairs up to 8'0 x 9'0. Anything larger than that falls outside what the 9550 is rated for. Note the height: at 9'0 tall, the 96 inch length covers a full 8 foot leaf but a 9 foot leaf needs a second piece or a longer run planned into the takeoff.
3) How much gap between the door and frame does the NGP 9550 need?
It is specified for 1/8 inch clearance between door and frame. The seal profile itself is 1-9/16 inches wide by 3/16 inch tall, so you need a flat face at least that wide on the edge or stop to land the adhesive on. Openings hung with wider gaps than 1/8 inch are outside the rated condition.
4) Does the NGP 9550 need screws, or is it self-adhesive?
Self-adhesive. It comes with a modified acrylic pressure sensitive adhesive and release liner, so it is peel and stick with no fasteners and no kerf routing. That is the practical difference from a channel-and-insert gasket like the Cal-Royal PG-601, which is an aluminum channel with a vinyl insert and gets mechanically fastened to the frame.
5) Does the NGP 9550 also stop smoke, or only fire?
Both. Alongside the intumescent function it carries Category G and H classification for smoke and draft control, which is what the flexible TPE fins do at ambient temperature. That matters on cross-corridor and stair doors where the requirement is smoke and draft control, not just the fire rating.
6) What is the difference between the NGP 9550 intumescent seal and Cal-Royal PG-601 perimeter gasketing?
They seal the same part of the opening in two different ways. The NGP 9550 is an edge intumescent fire and smoke sealing system built on a rigid PVC base with flexible TPE fins, applied with a modified acrylic pressure sensitive adhesive and release liner, and its intumescent material expands 8 to 10 times its original thickness at 375 F to 400 F to close the gap during a fire. Its profile is 1-9/16 inches wide by 3/16 inch tall and it is rated for 20, 45, 60 and 90 minute category B wood doors, perimeter and meeting edge, with 1/8 inch clearance. The Cal-Royal PG-601 is aluminum channel perimeter gasketing with a vinyl insert, so it is a rigid metal carrier fastened to the frame with a replaceable vinyl sealing element rather than an adhesive-applied intumescent strip. Choose the 9550 when the requirement is intumescent expansion on a fire rated wood door; choose an aluminum channel gasket when the job calls for a fastened metal retainer with a serviceable insert.
7) At what temperature does the 9550 intumescent seal actually expand?
It activates at 375 F to 400 F and swells 8 to 10 times its original thickness, closing the gap around the leaf once a fire is developing. Below that it just sits there as a fin seal, so normal door operation and normal building temperatures do not set it off. Service range on the material is -60 F to 275 F.
8) Which lengths and colors does the NGP 9550 come in, and how do I order for a pair of doors?
Two lengths, 84 and 96 inches, each in gray or brown. Both colors come in both lengths. Order per edge, not per door: a perimeter application takes two jamb runs plus the head, and a pair also takes the meeting edges, so count every edge on the takeoff before you set quantity.
9) Should I use adhesive intumescent seal or an aluminum channel perimeter gasket on my frames?
Pick by what the opening has to do. The 9550 is the choice when the assembly needs an intumescent seal on a rated category B wood door, because it expands 8 to 10 times at 375 F to 400 F to close the gap in a fire. If the job is plain perimeter sealing on a non-rated opening and you want a mechanically fastened, replaceable insert, the Cal-Royal PG-601 aluminum channel gasketing with vinyl insert is the type to look at instead.
10) Will the 9550 adhesive hold on an exterior door that sees real heat?
The seal material runs -60 F to 275 F, but the adhesive is the limiting part: its long term exposure rating is -30 F to 250 F. On sun-loaded or high heat locations that adhesive figure is the number to design to, not the 275 F.
11) For a hospital or school corridor door, which perimeter seal handles cleaning chemicals and hygiene requirements better?
The NGP 9550 is the one specified with those conditions in mind. Its rigid PVC base and TPE fins resist aging, weathering, UV radiation, water, detergent, alcohol and chemical exposure, and the material carries an anti-microbial additive to inhibit growth of microorganisms on the seal surface, which matters in healthcare, educational and food service environments. It also operates from -60 F to 275 F, with the adhesive rated for long term exposure from -30 F to 250 F. The Cal-Royal PG-601 is aluminum channel gasketing with a vinyl insert, so its wearing surface is vinyl carried in a metal channel and the insert is the element that gets replaced over time. On a frequently cleaned corridor door where the seal is also doing fire and smoke duty, the 9550 covers both the wipe-down exposure and the rated edge condition.
12) Which perimeter seal installs without drilling or fasteners in the frame?
The NGP 9550 mounts with a modified acrylic pressure sensitive adhesive and release liner that gives high initial adhesion and long term holding power, so it goes on the door edge or frame face with no fasteners and no prep to the frame. That makes it workable on occupied openings and on existing frames a contractor does not want to drill. The Cal-Royal PG-601 is aluminum channel gasketing with a vinyl insert, a channel carrier that mounts as a metal section rather than a peel-and-stick strip. The trade-off runs the other way on service: the 9550 is a bonded strip replaced as a whole, while a channel gasket keeps its carrier in place and takes a new insert. The 9550 comes in 84 inch and 96 inch lengths in gray and brown.
13) Is the 9550 seal OK for a hospital or school where things get washed down?
Yes. The rigid PVC base and TPE fins resist water, detergent, alcohol and chemical exposure as well as UV and aging, and the material carries an anti-microbial additive to inhibit microorganism growth. That combination is why it gets specified in healthcare, education and food service corridors. Materials are REACH and RoHS compliant.
