NGP 135NA-36 – Frequently Asked Questions

1) What lengths does the NGP 135NA perimeter seal come in, and how do I cover a standard commercial opening?
The 135NA comes in 36, 48, 72, 84 and 96 inch lengths. For a single opening you order the head piece and the two jamb pieces separately, so a typical 3070 door takes a 36 inch across the head and two 84 inch legs down the jambs. Taller frames get the 96 inch. The aluminum retainer is cut to length on site, so ordering the next size up and trimming is normal practice.
2) Will the NGP 135NA neoprene seal hold up in an unconditioned warehouse or a freezer vestibule?
Temperature range on the 135NA runs -81 F to 275 F, so unheated warehouses, loading docks and cold vestibules are inside its working range. The seal is a synthetic rubber polymer blend of Chloroprene and EPDM with good resistance to ozone, sunlight and aging, which is what keeps it from going hard and losing its seal after a couple of seasons on an exterior opening.
3) Is the NGP 135NA perimeter seal BHMA certified for a spec that calls out ANSI/BHMA A156.22?
Yes. The 135NA is BHMA certified to ANSI/BHMA A156.22 performance tests for heat and cold. That is the gasketing standard specifiers write into door hardware schedules, so it will satisfy an A156.22 line item on the drawing.
4) What fasteners come with the NGP 135NA seal, and can I adjust it after it's mounted?
Each piece ships with #6 x 3/4 inch stainless steel sheet metal screws. The holes in the aluminum retainer are slotted, so you can set the screws, close the door, and shift the retainer in or out until the neoprene just kisses the door face before you snug them down. That adjustment is the whole point of a screw-applied perimeter seal versus a tape-on product.
5) Does perimeter gasketing like the NGP 135NA seal the gap under the door too?
No. A perimeter seal covers the head and the two jambs only. The gap at the threshold needs a separate part, either a door bottom or sweep on the door or an automatic door bottom for a smoke or sound rated opening. Order the perimeter lengths and the bottom seal together, or the opening still leaks at the floor.
6) What is the difference between the NGP 135NA neoprene perimeter seal and the Cal-Royal PG-601?
Both are aluminum channel perimeter gaskets that mount to the frame stop, and the difference is the sealing element carried in the channel. The Cal-Royal PG-601 is an aluminum channel perimeter gasketing with a vinyl insert. The NGP 135NA carries a synthetic rubber polymer blend of Chloroprene and EPDM in an aluminum alloy 6063, T5 temper channel, rated from -81 F to 275 F and certified to ANSI/BHMA A156.22 heat and cold performance tests. If a submittal calls out a BHMA-certified seal or the opening sees extreme heat or cold, the 135NA is the one written to that standard; for a straightforward interior weather or light seal, the vinyl-insert PG-601 covers the same channel-mounted geometry.
7) Should I use a screw-on aluminum perimeter seal or the tape-on version?
Screws are the durable answer on a commercial opening: stainless #6 x 3/4 inch fasteners into the frame, slotted for adjustment, and the seal can be re-set or replaced years later. The 135NA also offers a FATT (Fast Attach Tape) option when you cannot drill the frame, which covers stainless or aluminum frames on a finish-sensitive job and retrofits where the existing frame is already full of holes. Tape trades adjustability for speed, so on a high-traffic entrance the screwed retainer is the one that stays put.
8) Is the NGP 135NA rated for commercial buildings or is it a residential weatherstrip?
Commercial. The 135NA is specified for office buildings, schools, hospitals, warehouses, government and municipal buildings, retail and multi-tenant residential. For an MRO buyer standardizing across a facility, the same profile in five lengths covers essentially every frame size in the building, which is why it works as a stocked item rather than a one-off order.
9) How is a neoprene perimeter seal different from a vinyl insert gasket like the Cal-Royal PG-601?
Both are aluminum channel perimeter gasketing that mounts to the frame stop. The difference is the sealing element: the NGP 135NA uses a Chloroprene and EPDM neoprene blend with stated abrasion resistance, memory retention and a -81 F to 275 F range, while the Cal-Royal PG-601 is an aluminum channel carrying a vinyl insert. Vinyl stiffens in deep cold; neoprene with memory retention is the choice where the door is exterior, sees hard traffic, or the seal has to keep its shape after years of compression.
10) Can a vinyl-insert perimeter gasket be used instead of a neoprene sponge seal on a hot or freezing opening?
Not interchangeably. The Cal-Royal PG-601 uses a vinyl insert in its aluminum channel, while the NGP 135NA uses a Chloroprene and EPDM sponge rated to operate from -81 F to 275 F with flame resistance, moisture resistance, and good resistance to ozone, sunlight and aging. On a boiler room, a walk-in freezer vestibule, or a sun-exposed exterior entrance where the seal has to hold memory through repeated temperature swings, specify the 135NA and its stated temperature range rather than assuming a vinyl insert behaves the same way.
11) We stock Cal-Royal PG-601 for our perimeter gasketing - what would we gain by standardizing on the NGP 135NA instead?
Both are aluminum channel perimeter gaskets, so the mounting approach on the frame stop is the same family of installation. What the NGP 135NA adds for a facility standard is a stated certification and temperature envelope you can put on a spec sheet: ANSI/BHMA A156.22 heat and cold performance certification, aluminum alloy 6063 T5 temper channel, and -81 F to 275 F service. It ships with #6 x 3/4 inch stainless steel sheet metal screws and slotted holes for adjustment, and comes in 36, 48, 72, 84 and 96 inch lengths so head and jamb runs come off the same part number. For institutional and government work where the seal has to be documented, that certification is usually the deciding factor.
12) What does the NGP 135NA look like once installed, and will it corrode on an exterior door?
Milled aluminum retainer with a black neoprene bulb. The frame is aluminum alloy 6063, T5 temper and anodized, which is what gives it corrosion resistance on exterior and coastal openings. On a dark bronze or painted frame the mill finish will read as a bright line, so if appearance matters on a lobby entrance, plan for that.
13) Is the NGP 135NA seal flame resistant?
The 135NA neoprene is flame resistant and moisture resistant, and BHMA certified to ANSI/BHMA A156.22. Flame resistant material is not the same as a labeled fire rating on the opening, so if your door assembly requires listed smoke or fire gasketing, confirm the specific product the schedule calls for.
