NGP 5050CL-17 – Frequently Asked Questions

1) Will the NGP 5050CL silicone seal work on a 3-hour rated hollow metal fire door?
Yes, for smoke control. The 5050CL carries category "H" smoke rating for hollow metal fire doors up to 3 hours, and up to 90 minutes on wood fire doors. Its separate category "G" edge sealing rating covers 20-minute rated wood doors only, so on a 3-hour hollow metal opening you are using it as a smoke seal, not as an edge seal for a rated wood assembly.
2) What size door can the NGP 5050CL edge seal be used on for a 20-minute wood fire door?
The category "G" edge sealing rating covers single swing doors up to 4'0 x 8'0 and pairs up to 8'0 x 8'0 on 20-minute rated wood doors. Anything taller or wider than that falls outside the rating, so an oversized opening needs a different seal.
3) How much gap will a 1/2 inch by 1/4 inch silicone smoke seal close on a door frame?
The 5050CL bulb measures 1/2 inch wide by 1/4 inch tall, so the 1/4 inch dimension is what stands off the stop and compresses against the door face. Frame gaps in that range close up; a much wider gap needs a taller profile. The 1/2 inch width is the adhesive footprint you need flat on the stop, so check you have that much clean, uninterrupted surface before ordering.
4) Do I need screws or a channel to install the NGP 5050CL, or does it stick on?
It sticks on. The 5050CL uses a modified acrylic pressure sensitive adhesive with a peel-off release liner, so there is no aluminum retainer, no drilling, and no fasteners. That makes it the choice for retrofitting an existing frame you do not want to drill. If you want a mechanically fastened perimeter gasket instead, the Cal-Royal PG-601 is an aluminum channel with a vinyl insert.
5) Is the NGP 5050CL seal certified to a smoke gasketing standard for my inspector?
It is BHMA certified to ANSI/BHMA A156.22, tested for heat, cold and air infiltration. That is the gasketing and edge seal standard an AHJ or fire door inspector will look for on a labeled opening.
6) What is the difference between the NGP 5050CL silicone seal and the Cal-Royal PG-601 perimeter gasketing?
They seal the same part of the opening by two different methods. The NGP 5050CL is a self-adhesive silicone seal, 1/2 inch wide by 1/4 inch tall, that mounts with a modified acrylic pressure sensitive adhesive and a peel-off release liner, so it goes onto the stop face of an existing frame with no fasteners and no frame prep. The Cal-Royal PG-601 is an aluminum channel perimeter gasketing with a vinyl insert, so the seal is carried in a rigid metal channel that is fastened to the frame and the vinyl insert rides in it. For a locksmith or contractor working an occupied opening, that is the deciding detail: the 5050CL adds no projection of hardware to fasten and the PG-601 puts an aluminum retainer on the frame. The 5050CL is also BHMA certified to ANSI/BHMA A156.22 and carries category G edge sealing for 20-minute rated wood doors and category H smoke control for up to 3-hour hollow metal and 90-minute wood fire doors, which is the specification an institutional buyer is matching when the drawing calls out a rated assembly.
7) Which roll length of the NGP 5050CL should I order for a single door opening?
Rolls come in 17, 20, 25 and 300 feet. A standard single 3'0 x 7'0 opening takes roughly 17 feet around head and both jambs, which is why the 17 foot roll exists, though it leaves nothing for error. The 20 or 25 foot roll gives you working slack on one opening; the 300 foot roll is the buy for a building-wide or multi-door retrofit.
8) Will a self-adhesive smoke seal hold up in an unconditioned or exterior door opening?
The 5050CL is rated from -100 F to 500 F and stays flexible across that range. The siloxane synthetic rubber polymer resists ozone, UV, moisture and aging, and the adhesive is called out for permanent mounting in both exterior and interior locations. That covers unheated stairwells, loading dock vestibules and mechanical rooms.
9) Can I use a silicone door seal in a room protected by FM200 or Halon?
Yes. The 5050CL is specifically recommended for spaces served by FM200 or Halon fire suppression systems. That matters in data centers, server rooms and telecom closets, where the seal has to hold the agent concentration in the room long enough to work.
10) When should a door get aluminum channel gasketing instead of a self-adhesive silicone seal?
Go to a housed gasket like the Cal-Royal PG-601, which is aluminum channel perimeter gasketing with a vinyl insert, when the opening needs the seal held mechanically rather than bonded to the frame face - the channel is fastened and the vinyl insert is retained by it, so the seal element is not depending on adhesion to the substrate. The NGP 5050CL suits the opposite case: an adhesive-mounted silicone seal for retrofit onto a frame that is staying as it is, rated for service from -100 F to 500 F and specifically recommended where FM200 or Halon fire suppression is in use. A property manager standardizing a corridor of doors usually picks on that basis - whether crews are fastening a retainer to each frame or wiping the stop clean and rolling a seal on.
11) Which perimeter seal is easier to install on an existing frame without modifying it?
The NGP 5050CL, because it is self-adhesive. The modified acrylic pressure sensitive adhesive gives high initial adhesion with long-term holding power for permanent mounting in both exterior and interior locations, and the protective release liner means installation is clean the stop, peel, and press - no drilling, no fasteners, no channel to cut and align. The Cal-Royal PG-601 is aluminum channel gasketing with a vinyl insert, which is a fastened retainer on the frame. It also comes in 17', 20', 25' and 300' rolls, so a single roll can carry an opening or a whole floor of them without splicing mid-jamb.
12) Will a clear smoke seal be visible on a painted or wood-grain frame?
The 5050CL is clear silicone, so it reads far less than a black or brown gasket on stained wood frames, painted jambs and finished lobby openings. On a fleet of doors with mismatched frame colors, one clear seal covers them all instead of matching stock per finish.
13) How long can I keep NGP 5050CL adhesive seal on the shelf before installing it?
One year, stored at 75 F and 50 percent relative humidity. That is a real constraint on the 300 foot roll: buy it for work you are doing now, not to sit in a stockroom for two seasons, or the pressure sensitive adhesive loses its initial tack.
14) Is this seal for commercial fire doors or will it work on a house door?
The 5050CL is a commercial product, built for rated openings in healthcare, schools, government buildings and multi-tenant residential. It will physically adhere to any frame, but the fire and smoke ratings and the A156.22 certification are what you are paying for, and those only mean something on a labeled fire door assembly.
