NGP 131NDKB – Frequently Asked Questions

1) Is the NGP 131NDKB long enough to seal the head of a standard commercial door opening?
The 131NDKB comes as an 84 inch extrusion, which is the length normally used for the head of a single opening. For the jambs on a 7 foot door you would need additional pieces cut to height, so plan on more than one length per opening if you are gasketing the full perimeter.
2) Does the NGP 131NDKB neoprene sponge seal meet ANSI/BHMA A156.22?
Yes. The 131NDKB is BHMA certified to ANSI/BHMA A156.22, including the heat and cold performance tests, which is the standard specifiers cite for door gasketing on institutional and government work.
3) Will this neoprene sponge seal hold up on an exterior door in a cold climate?
It is rated from -20 F to 200 F, so it covers winter exterior service and hot sun-loaded south elevations alike. The closed cell elastomeric foam also carries good resistance to ozone, sunlight and aging, which is what matters on a door that sits in weather year round.
4) Do I need to buy fasteners separately to install this NGP gasketing?
No, mounting screws come with it. Each length ships with #6 x 3/4 inch stainless steel sheet metal screws, and the extrusion is punched with slotted holes so you can shift the seal in or out against the door face to set compression before you tighten down.
5) What is the difference between the NGP 131NDKB neoprene sponge seal and the Cal-Royal PG-601 perimeter gasketing?
Both are aluminum-channel perimeter seals applied to the door frame, but the sealing element differs. The NGP 131NDKB uses a closed cell elastomeric foam made from a synthetic rubber polymer blend of PVC, nitrile rubber (NBR) and chloroprene, carried in an 84 inch aluminum alloy 6063 T5 extrusion in dark bronze, and it is BHMA certified to ANSI/BHMA A156.22 with a service range of -20 F to 200 F. The Cal-Royal PG-601 is an aluminum channel perimeter gasketing with a vinyl insert. If the specification calls for a compressible sponge seal with the A156.22 heat and cold certification, the 131NDKB is the one that carries it; if the job simply calls for a vinyl-bulb perimeter gasket, the PG-601 is the equivalent style.
6) Will dark bronze weatherstripping match existing bronze door frames and hardware?
The aluminum extrusion on the 131NDKB carries a dark bronze finish, so it reads as a dark brown tone against bronze-anodized frames and dark finish hardware rather than standing out like mill aluminum. It is the only finish this particular part is built in, so if some of your openings are clear aluminum you will be ordering a different finish variant for those.
7) What is the seal material on the NGP 131NDKB, and is it rubber or vinyl?
The sealing element is a closed cell elastomeric foam, a synthetic rubber polymer blend of PVC, nitrile rubber (NBR) and chloroprene. It is flame resistant and moisture resistant with good abrasion resistance, tensile strength and memory, so it recovers its shape after repeated door closings instead of taking a set like a plain soft vinyl bulb.
8) Is a sponge seal or a vinyl insert gasket the better choice for a commercial frame?
A sponge seal like the NGP 131NDKB compresses across a wider gap and recovers, which suits doors with some variation in fit and exterior openings that need heat and cold performance. A vinyl insert channel gasket, such as the Cal-Royal PG-601 aluminum channel perimeter gasketing, is the simpler perimeter option where the door hangs consistently and you mainly want a light dust and draft seal. Both mount to the frame stop; the difference is how much irregularity the sealing element will take up.
9) Can I use this on a pair of doors or does it only work on single openings?
The 131NDKB is perimeter gasketing that mounts to the frame head and jambs, so on a pair it seals the head and both outer jambs. The meeting stiles in the middle of a pair need an astragal, not this seal, so order that separately for double-door openings.
10) Can the Cal-Royal PG-601 be used in place of the NGP 131NDKB on an exterior commercial opening?
They are both aluminum channel perimeter seals that mount to the frame, so they occupy the same place on the opening, but they are not the same seal. The NGP 131NDKB is a commercial neoprene sponge seal with a closed cell elastomeric foam blend and BHMA certification to ANSI/BHMA A156.22 for heat and cold, rated from -20 F to 200 F, with good resistance to ozone, sunlight and aging for exterior use. The Cal-Royal PG-601 seals with a vinyl insert. On an exterior door where the submittal cites A156.22 or a temperature range, specify the 131NDKB; the PG-601 is the vinyl-insert alternative where those conditions are not called out.
11) For matching a dark bronze storefront or entrance, which perimeter seal should be specified?
The NGP 131NDKB ships with a dark bronze finished aluminum extrusion in an 84 inch length, so the visible channel matches dark bronze frames and hardware without field painting. It mounts with the supplied #6 x 3/4 inch stainless steel sheet metal screws through slotted holes, which let the installer adjust compression against the door face after hanging. The Cal-Royal PG-601 is the comparable aluminum channel perimeter gasket with a vinyl insert if the sponge seal profile is not required.
12) Is the aluminum on this seal strong enough for a high-traffic entry?
The extrusion is 6063 T5 temper aluminum alloy, a structural architectural temper with corrosion resistance suited to exterior frames. Combined with the abrasion resistant foam it is built for commercial rather than residential duty, which is how the 131NDKB is classified.
