Zero International 188S-18-BK – Frequently Asked Questions

1) Can Zero 188S gasketing be installed on existing door frames without drilling or screws?
No drilling, no fasteners. The 188S is backed with 3M self-adhesive tape, so it presses onto the stop face of a frame that is already hung and finished. That is the reason to pick it for occupied buildings: you are not pulling doors, drilling frames, or touching the paint, and one person can do a run of openings in an afternoon. Screw-applied seals in an aluminum carrier need layout, pilot holes and fasteners at every piece.
2) Should I use adhesive-backed perimeter gasketing or an aluminum channel seal on my commercial doors?
It comes down to the frame condition and how much abuse the seal takes. Adhesive gasketing like the Zero 188S goes on with 3M tape and no fasteners, which suits retrofit on frames already in service and openings you cannot take out of use. An aluminum carrier seal screws to the stop and holds the seal in a rigid channel, which holds up better on high-traffic and abuse-prone openings and lets you replace the insert without redoing the whole run. If that is the direction you want, the Cal-Royal PG-601 is an aluminum channel with a vinyl insert, and the NGP 155V is a vinyl seal in a mill aluminum frame. For a compressible sponge seal in a screw-applied housing, the NGP 108NA carries neoprene sponge in an anodized aluminum frame.
3) The stop face on our frames is painted and chalky, so adhesive tape will not hold. What perimeter seal can we use instead of the Zero 188S?
The Zero International 188S applies with 3M self-adhesive tape to the stop, so it depends on a clean, sound surface to bond to. Where the stop cannot be relied on for adhesion, a seal carried in a rigid frame that fastens to the stop is the alternative: the NGP 155V is a vinyl perimeter seal with a mill aluminum frame, and the Cal-Royal PG-601 is an aluminum channel perimeter gasketing with a vinyl insert. Both put the sealing element in a screw-applied carrier rather than sticking it directly to the frame, and both change the profile the buyer sees on the jamb, since a channel stands proud of the stop where the 188S sits flat against it.
4) We are sealing a conference room door for sound. What are our options besides the Zero 188S?
The Zero International 188S is Sound Seal Rated and uses the Compress-O-Matic design, which lets the installer fine-tune how hard the seal compresses against the door as it closes, so an acoustic opening can be dialed in after hanging. The other approach in an acoustic opening is a magnetic seal: the NGP 159MA is a magnetic seal in an anodized aluminum housing, supplied at 84 inches, which pulls itself against the door face when the door closes rather than being set by compression adjustment. The 188S is set once by the installer and stays where it is set; the 159MA relies on magnetic attraction to a ferrous door face, so it is an option only where the door itself is steel.
5) What colors does the Zero 188S self-adhesive gasketing come in, and are all colors available in every length?
Three colors: black, brown and white. Every one of them is offered in all four lengths, 17, 18, 20 and 21 feet, so you can match the seal to painted frames, dark bronze frames and wood tone frames across a building without changing lengths or mixing product. That matters on tenant-facing openings where the seal sits in plain view on the stop.
6) What can I put on drafty apartment or office entry doors to stop air infiltration?
Zero International 188S is Air Seal Rated perimeter gasketing built for commercial openings, and the 3M adhesive backing means it goes on existing frames with no drilling, which is what makes it practical across a whole building of occupied units. It seals the head and jambs; pair it with a door bottom or sweep to close the gap at the sill, since that is where most of the draft in an entry door comes through.
7) My door does not sit evenly against the stop. Will Zero 188S gasketing still seal along the whole perimeter?
That is what the Compress-O-Matic design is for. It lets you fine tune compression along the run rather than relying on one fixed projection, so a door that bears harder at the strike side than at the head can still be brought to a consistent seal. It will not correct a badly out of square frame or a door that is dragging, but for the usual variation in gap you get across an older opening it gives you adjustment instead of a take-it-or-leave-it fit.
8) Is there an anti-ligature version of Zero 188S gasketing for behavioral health rooms?
Yes. The 188S is offered in a Zero Anti-Ligature Gasketing (ZAG) configuration as a special order, for patient rooms and holding areas where standard gasketing is a ligature point. The stock 17, 18, 20 and 21 foot black, brown and white runs are the standard configuration, so the ZAG version has to be specified as such when you order rather than picked off the shelf.
9) Is a nylon brush seal the same thing as the Zero 188S for stopping air infiltration?
No, they seal by different means. The Zero International 188S is Air Seal Rated and works by compression, with the Compress-O-Matic adjustment setting how firmly the seal bears on the door so the gap is closed. The NGP 602A is a nylon brush seal in an anodized aluminum housing, and a brush seal works by sweeping filament across the gap, which suits dust, light, and debris control at a door that moves often. A buyer specifying for energy performance or air infiltration control at a commercial opening is asking for a compression seal, which is what the 188S is; a buyer who needs a sweeping element that tolerates a door dragging across it is asking for the brush.
10) What perimeter seal should I use on a walk-in cooler vestibule or a boiler room door where temperatures swing hard?
For an opening that has to hold a seal across a wide temperature swing, the NGP 108NA is a neoprene sponge seal in an anodized aluminum frame carrying a stated temperature range of -20 F to 200 F, which is the specification a mechanical contractor can put against a cold-storage or equipment-room drawing. The Zero International 188S is a commercial perimeter seal with Sound Seal and Air Seal ratings and a 3M self-adhesive application, which suits the conditioned interior openings that make up most of a building - offices, classrooms, patient rooms, corridors. Note also that the 108NA seats in a fastened aluminum frame, so it does not depend on an adhesive bond that a cold or hot surface would work against.
11) I need the seal to disappear against a dark painted wood frame. Which one visually matches?
The Zero International 188S is supplied in black, brown, and white, so the seal can be ordered to sit against a painted or stained frame without an aluminum line running down the jamb. The aluminum-carrier seals read differently on the frame: the NGP 108NA, the NGP 159MA, and the NGP 602A all use anodized aluminum, and the NGP 155V uses a mill aluminum frame. On a hollow metal frame in an aluminum storefront or a back-of-house corridor those read as intended; on stained wood or dark paint in a lobby or guest corridor, the brown or black 188S is the one that blends.
12) I am gasketing a punch list of twenty doors. Do I buy by the coil or by the opening?
Those are the two ways this hardware is sold and it changes how a crew works through a list. The Zero International 188S comes in 17, 18, 20, and 21 foot lengths, which is bulk stock a crew cuts to the head and both jambs on site, so one length can carry more than one opening and the offcuts absorb odd frame heights. The NGP 159MA magnetic seal is supplied as an 84 inch piece, which is bought per jamb or per head and arrives at the length it installs at. For a mixed fleet of frame sizes the coil is the flexible buy; for a repeat standard opening the fixed length removes the cutting.
13) What perimeter seal should I use on a freezer, cold storage or boiler room door?
For openings that swing between temperature extremes, the NGP 108NA neoprene sponge seal is the one to look at: it is rated for a service range of -20 F to 200 F and carries the sponge in an anodized aluminum frame that screws to the stop. Mechanically fastened carrier seals are the usual choice on those doors because there is no adhesive bond in the assembly to be worked on by heat, cold or condensation.
14) Is a nylon brush seal the same thing as adhesive perimeter gasketing?
Not the same job. A brush seal such as the NGP 602A carries nylon filament in an anodized aluminum housing and wipes rather than compresses, which is why it gets used where a door slides or where a compression seal would drag and get torn off. Zero International 188S is a compression type perimeter seal, Sound Seal Rated and Air Seal Rated, and it works by being squeezed between door and stop. If the target is acoustic and air infiltration control on a swinging door, they are not interchangeable.
15) Adhesive gasketing or a magnetic seal for hollow metal door frames?
A magnetic seal only works if there is a ferrous door face for it to pull against, so it is a hollow metal answer and not a wood or aluminum one. The NGP 159MA magnetic seal comes as an 84 inch anodized aluminum piece, meaning you order per run and figure the head and each jamb separately. Zero International 188S does not care what the door is made of, since it seals by compression with a 3M adhesive backing, and it comes in continuous 17 to 21 foot lengths you cut to the opening. On steel frames both are live options; on wood or aluminum, the magnetic seal is out.
16) Our other doors have an aluminum channel gasket screwed to the stop. Can we put the Zero 188S on the rest of the building and have it look consistent?
They will not look the same on the frame, so decide that before splitting a building. A channel-carried seal like the Cal-Royal PG-601, an aluminum channel perimeter gasketing with a vinyl insert, or the NGP 155V vinyl perimeter seal with a mill aluminum frame, shows a metal channel running the perimeter and is serviced by replacing the insert in the existing channel. The Zero International 188S is a self-adhesive strip applied with 3M tape directly to the stop in black, brown, or white, with no channel on the frame. Where a floor or wing is being done as a unit, matching within that unit keeps the appearance consistent even if the rest of the building carries channel.
