Zero 8144 Self Adhesive Silicone Weatherstripping Black Finish

The Zero 8144S is commonly referred to as a “Bat-Wing” seal because of the profile of this product with a design feature of two sealing wings coming into contact with both sides of the corner of the door when it is in a fully closed position. This seal is discreetly fixed into the corner of the rebated stop around the frame of the door using the uncompromising adhesive properties of leading 3M pressure-sensitive adhesive (3M PSA). Providing long-lasting adhesion to the door frame ensuring high performance. It is formed out of high-quality silicone, with long-lasting memory form to ensure that it keeps its shape for years to come.

  • Fire-rated – UL10C
  • Smoke tested – UL1784
  • Smoke and draft control tested
  • Air infiltration tested
  • Sound tested

Zero International 8144SBK204 – Frequently Asked Questions

1) Where does the Zero 8144 bat-wing seal actually mount on a door frame?
The 8144S mounts in the corner of the rebated stop on the frame, not on the face of the stop and not on the door itself. Two sealing wings contact both sides of the door corner when it closes, so one strip handles the head and both jambs. Fixing is 3M pressure-sensitive adhesive, so there's no drilling, no screws, and no aluminum carrier to cut and fasten. That makes it a fast retrofit on an existing frame where you don't want to touch the stop.
2) Is the Zero 8144 weatherstripping fire rated for a labeled opening?
Fire rated to UL10C, and smoke tested to UL1784. It has also been tested for smoke and draft control, air infiltration, and sound. That combination is what a facility or institutional buyer needs on a labeled corridor or stair door where the opening has to hold both fire and smoke.
3) How many feet of Zero 8144 do I need for one door opening?
The 8144S is sold as continuous coil in 8, 17, 21, and 25 foot lengths, and you cut it on site. A single 3-0 x 7-0 opening takes roughly 17 feet for two jambs plus the head, which is why 17 feet is the common single-door buy. The 8 foot piece suits a jamb-only repair or a short patch, and 21 and 25 foot rolls cover taller frames or a pair of doors. Order by total perimeter, not by door count.
4) Can I install the Zero 8144 gasketing without screwing anything into the frame?
Yes, and that's the point of it. The 8144S fixes with 3M pressure-sensitive adhesive into the corner of the rebated stop, so nothing is drilled or fastened. Compare that with the screw-applied alternatives: the Cal-Royal PG-601 uses an aluminum channel with a vinyl insert, the NGP 155V a mill aluminum frame, and the NGP 602A a nylon brush in an anodized aluminum housing. All three need the housing cut to length and mechanically fastened. If the frame is painted, historic, or you can't put holes in it, the adhesive-set silicone is the one to reach for.
5) Will Zero 8144 bat-wing seal work on a flat frame with no rabbet?
No. The 8144S seats in the corner of a rebated stop, and the two wings work by pressing against the door corner from that position. On a flat or non-rebated frame there is no corner to set it into and the wings have nothing to bear on. For that condition use a surface-applied perimeter seal that screws to the face of the stop, such as the NGP 155V vinyl perimeter seal in a mill aluminum frame or the Cal-Royal PG-601 aluminum channel with vinyl insert.
6) Will the Zero 8144 seal a door bottom or threshold gap?
No. The 8144S is perimeter gasketing for the head and jambs only, seating into the frame's rebated stop. The bottom of the door has no frame stop to adhere to and the door swings clear of it, so you need a separate door bottom, sweep, or threshold to close that gap. Budget for both parts if you're chasing smoke or draft control on the whole opening.
7) Which perimeter seal holds up on a door that sees wide temperature swings, like an exterior stair or a loading area?
The Zero 8144 is formed of high-quality silicone with long-lasting memory form so it keeps its shape over time, which is what carries it through repeated heat and cold cycling. If a neoprene seal in an aluminum carrier is preferred instead, the NGP 108NA is a neoprene sponge seal in an anodized aluminum frame with a stated temperature range of -20 F to 200 F. Both are perimeter seals for the stop; the 8144 sticks with adhesive into the corner of the rebate, the 108NA mounts on its aluminum frame.
8) I need a smoke and draft seal on a fire door - is a brush seal an acceptable substitute for the Zero 8144?
No. The NGP 602A is a nylon brush seal in an anodized aluminum housing, and a brush is a sweeping seal meant for debris and light air movement, not a compression seal against the stop. The Zero 8144 is a silicone bat-wing that contacts both sides of the door corner when the door is fully closed, and it is fire-rated to UL10C, smoke tested to UL1784, and smoke and draft control tested. For a fire or smoke opening, the 8144 is the seal doing that job; the 602A is the different product it is often mistaken for.
9) Silicone or neoprene weatherstripping, which should I use on a commercial door?
Silicone is the choice when the seal has to survive heat and hold its shape. The 8144S is high-quality silicone with long-lasting memory form, so the wings recover after years of door slams rather than taking a set. Neoprene sponge is the alternative if you want a softer, more compressible seal, and the NGP 108NA neoprene sponge seal is rated for a temperature range of -20 F to 200 F. The other practical difference is the carrier: the 8144S is bare adhesive-backed profile, while the 108NA rides in an anodized aluminum frame you screw to the stop.
10) Is Zero 8144 weatherstripping rated for commercial use or is it a residential product?
Commercial. The 8144S is specified for commercial openings, and the UL10C fire rating and UL1784 smoke test are the ratings a commercial or institutional opening is inspected against. It's the same product a property manager can standardize across a building's corridor doors, since it's cut from coil rather than ordered to each frame size.
11) Will a brush seal do the same job as the Zero 8144 silicone bat-wing?
Not for smoke or draft. A nylon brush seal like the NGP 602A, in its anodized aluminum housing, sweeps debris and cuts drafts but doesn't form a positive compression seal. The 8144S is solid silicone that its two wings press against the door corner, and it carries UL10C fire rating and UL1784 smoke testing. If the opening is labeled or you're chasing an air infiltration or smoke-and-draft requirement, the brush is not a substitute.
12) Can I use the Cal-Royal PG-601 in place of the Zero 8144 on a standard commercial door frame?
They seal different parts of the opening in different ways. The Cal-Royal PG-601 is an aluminum channel perimeter gasketing with a vinyl insert, so it screws to the stop as a channel and the vinyl insert carries the seal. The Zero 8144 is an adhesive-mounted silicone bat-wing that seats in the corner of the rebated stop with 3M pressure-sensitive adhesive, and it is fire-rated to UL10C and smoke tested to UL1784. If the frame is already prepped for a screw-applied channel, the PG-601 fits that prep; the 8144 is the choice where the seal must go in without drilling the frame.
13) What seals a pair of doors or an opening that needs a positive pull-shut, instead of the Zero 8144?
The NGP 159MA is a magnetic seal in an 84 inch anodized aluminum extrusion, so the seal is drawn against the door rather than compressed by it - that is the option when the opening needs the door pulled tight to the stop. The Zero 8144 seals by compression: two silicone wings meet both sides of the door corner as the door closes, with no metal extrusion and no cutting to a fixed length, since it comes in 8, 17, 21 and 25 foot coils.
14) Which perimeter seal can I standardize on across a facility with both fire-rated and non-rated openings?
The Zero 8144 covers both: it is a commercial silicone perimeter seal that is fire-rated to UL10C, smoke tested to UL1784, smoke and draft control tested, air infiltration tested and sound tested, so the same part number works on rated and non-rated doors. Facility-wide, that avoids running separate seals for each opening class. The aluminum-carrier alternatives are single-purpose by construction - the NGP 155V is a vinyl perimeter seal on a mill aluminum frame and the NGP 602A is a nylon brush seal in an anodized aluminum housing - each cut and screwed per opening.
15) Does Zero 8144 gasketing help with sound transmission between rooms?
It's been sound tested, along with air infiltration testing. The mechanism is the two-wing profile sealing both sides of the door corner at once, which closes the perimeter gap more completely than a single-contact seal. For an office or exam room where noise is the complaint, that dual contact is the reason to pick the bat-wing profile. A magnetic seal like the NGP 159MA is the other approach, pulling the door tight to an anodized aluminum frame.
16) What color does the Zero 8144 self adhesive silicone seal come in?
Black only, in every length. On a dark or bronze frame it disappears into the rebate; on a light-painted or aluminum frame it will read as a visible black line at the stop corner. Worth knowing before you order for a lobby or a front-of-house opening where appearance matters.
17) Is there an install sheet for the Zero 8144 weatherstripping?
Zero publishes install instructions for the 8144, and the seal is also covered in Zero's full line catalog. The install itself is short: clean the rebate corner, peel the liner, and press the strip in place, since the 3M pressure-sensitive adhesive is the only fixing. Surface prep is what determines whether the adhesion holds long term.
