Zero International 117S-BK 12 – Frequently Asked Questions

1) Will the Zero 177S self-adhesive seal work on a door frame that's already painted or finished, without drilling?
No fasteners needed. The 177S sticks down with 3M self-adhesive tape, so it goes onto the frame stop or door face with no drilling and no screw holes. That's the reason property managers reach for it on occupied units and on frames they don't want to punch. The trade-off is the usual one for tape-mounted gasketing: the surface has to be clean and sound for the tape to hold. If you're gasketing a frame where you'd rather have mechanical fastening, a kerf or surface-applied housing seal such as the NGP 155V vinyl perimeter seal with a mill aluminum frame is the other route.
2) How much door opening does one 12 foot roll of Zero 177S cover?
One pack of the 177S is a single 12 foot length in black. On a standard 3070 single door you'd use roughly 7 feet up each jamb and about 3 feet across the head, so one 12 foot piece does not wrap a full three-sided perimeter on its own. Plan two lengths per opening for head and both jambs, or one length if you're only sealing the head and one jamb.
3) Silicone or vinyl or neoprene weatherstripping, which should I use on a commercial door?
The gasket material is the decision. The 177S uses a silicone bulb, which keeps its flexibility across a wide temperature swing and takes compression set less readily, so it's the pick for exterior openings, hot mechanical rooms and any door where acoustic performance matters. Vinyl, as on the NGP 155V, is the general-purpose interior choice. A neoprene sponge like the NGP 108NA is rated by the maker for -20 F to 200 F. If you're sealing a door that has to sweep dust or debris rather than seal air, none of those apply and you want a brush seal such as the NGP 602A.
4) Can I use the Zero 177S on a fire rated door?
The 177S is a Sound Seal and Air Seal rated perimeter gasket. Smoke and fire door gasketing is a separate rating, and where an opening is fire rated the gasketing on it has to carry the listing your inspector is checking for. Use the 177S where the job is air infiltration and acoustics.
5) What is the difference between the Zero 177S adhesive door seal and an aluminum channel perimeter gasket like the Cal-Royal PG-601?
They mount two different ways. The Zero 177S is a self-adhesive silicone gasketing set backed by 3M tape, so it applies directly to the door or frame surface without mechanical fasteners. The Cal-Royal PG-601 is an aluminum channel perimeter gasket with a vinyl insert, so it carries a rigid retainer that fastens to the frame and holds a replaceable vinyl bulb. On a retrofit where you do not want to drill the frame, the adhesive-mounted 177S is the one that goes on without prep; where the seal element gets replaced repeatedly over the life of the opening, the channel-and-insert design of the PG-601 lets the insert be pulled and renewed without disturbing the retainer.
6) Is the NGP 602A brush seal a substitute for the Zero 177S door seal?
No, and it is worth knowing why before ordering. The NGP 602A is a nylon brush seal in an anodized aluminum housing. A brush seal closes a gap with bristles, which sweeps debris and tolerates an irregular gap but does not form a continuous compressed barrier. The Zero 177S is a silicone gasketing set on 3M self-adhesive tape, rated Sound Seal and Air Seal, designed to hold consistent contact along the door perimeter for acoustic and air infiltration control. If the goal is stopping sound and air transfer, the 177S is the compression-contact product; the brush construction of the 602A serves openings where sweeping action across a wider or less uniform gap is the requirement.
7) For a sound-rated office door, is the Zero 177S silicone seal or the NGP 159MA magnetic seal the right choice?
Both address the same acoustic problem from different mechanics. The Zero 177S uses a silicone gasketing set on 3M self-adhesive tape and is Sound Seal and Air Seal rated, with an adjustable design that lets contact be fine-tuned along the perimeter after installation. The NGP 159MA is a magnetic seal in an anodized aluminum frame, supplied at 84 inches, which pulls the seal element against a steel door face by magnetic attraction rather than by compression. The magnetic approach requires a ferrous door or frame member for the magnet to grab; the 177S silicone seal does not care what the door is made of, so it is the workable option on aluminum, wood, or fiberglass door leaves.
8) What seal should be used instead of the Zero 177S on a door that sees high heat or cold, such as a mechanical room or exterior loading door?
Look at the NGP 108NA. It is a neoprene sponge seal in an anodized aluminum frame with a published temperature range of -20 F to 200 F, which is the spec to work from when the opening sees extremes at either end. The Zero 177S is a silicone self-adhesive gasketing set on 3M tape, engineered for commercial perimeter sealing with Sound Seal and Air Seal ratings, and it suits interior commercial openings in offices, schools, healthcare, and multi-tenant residential where acoustic and air infiltration control is the requirement. Where the driving condition is temperature rather than sound, the 108NA is the one carrying the rated range.
9) Is the Zero 177S any good for sound control, or is it just a draft seal?
Both. The 177S carries a Sound Seal rating and an Air Seal rating, which is why it shows up on conference rooms, exam rooms and demising walls between tenants rather than only on exterior openings. The silicone gasket stays flexible and holds contact along the door edge, and the sealing system is adjustable so contact can be tuned as the door settles.
10) My office door still leaks sound after new weatherstripping, will an adjustable seal fix it?
That's the case the 177S is built for. Its sealing system is adjustable, so the gasket can be set for consistent contact rather than relying on the door hanging exactly where it did on day one, and the silicone bulb keeps pressure along the edge as the door settles. Sound Seal and Air Seal ratings both apply. Worth knowing before you order: a perimeter seal only fixes the head and jamb leaks, so if the door has an undercut you'll still hear through the bottom until a door bottom goes on with it.
11) What is the difference between the Zero 177S silicone seal and the NGP 155V vinyl perimeter seal?
The seal material and the mounting method both differ. The NGP 155V is a vinyl perimeter seal carried in a mill aluminum frame for commercial door weatherstripping, so the vinyl element is held in a metal retainer that fastens to the frame. The Zero 177S is a silicone gasketing set on 3M self-adhesive tape with no retainer, applied directly to the surface. Silicone and vinyl behave differently over time and against temperature swing, and the mill aluminum frame on the 155V presents a metal face at the stop where the 177S presents only the black gasket. On an opening where the frame cannot be drilled, the adhesive-mounted 177S installs without fasteners.
12) Which perimeter seals come in a fixed length versus a cut-to-length roll for standardizing across a building?
The Zero 177S is supplied in a 12 foot length in black, which covers a standard single opening head and both jambs with material to trim from one piece. The NGP 159MA magnetic seal is supplied at 84 inches, a per-piece length matched to a jamb run. For a facility standardizing perimeter seal across many doors, the 12 foot supply of the 177S means fewer pieces handled per opening and one adhesive-mounted product to stock, since it needs no fasteners or retainer channel.
13) Which door seal installs fastest on an occupied building with no drilling?
The Zero 177S. Its silicone gasketing set is backed by 3M self-adhesive tape for quick, tool-free application to door and frame surfaces, with no mechanical fasteners required, so an occupied suite or classroom does not need a drill or a frame prep. The alternatives in the same sealing role carry rigid retainers that mount to the frame - the Cal-Royal PG-601 is an aluminum channel with a vinyl insert, the NGP 155V a vinyl seal in a mill aluminum frame, and the NGP 602A a nylon brush in an anodized aluminum housing. Those retainer-mounted designs put a replaceable insert in a permanent channel, which is the tradeoff against the surface-applied 177S.
14) Does the Zero 177S come in anything other than black?
Black is the finish for the 177S, in a 12 foot length. If the opening calls for an anodized aluminum look rather than a black gasket, an aluminum-framed seal is the alternative, such as the NGP 108NA with its anodized aluminum frame or the NGP 159MA magnetic seal in anodized aluminum at 84 inches.
15) Is the Zero 177S rated for commercial use or is it a residential weatherstrip?
Commercial. Zero classes the 177S as a commercial perimeter seal, and it's used on office buildings, schools, healthcare, retail, warehouse, multi-tenant residential and government facilities. For a facility standardizing gasketing across a building, it's a single tape-applied part that suits both interior acoustic doors and exterior openings.
