NGP 127SDKB-36 – Frequently Asked Questions

1) Will a silicone perimeter seal hold up in a boiler room or a walk-in freezer vestibule?
Both ends of that range are covered. The 127SDKB uses a microcellular silicone core rated from -100 F to 500 F and stays flexible at those extremes, so it keeps its memory and seal in freezer vestibules and in high heat mechanical spaces where standard vinyl or neoprene stiffens and takes a set.
2) Is this NGP seal acceptable for a room protected by FM200 or Halon fire suppression?
Yes. NGP recommends the 127SDKB closed cell sponge seal for spaces served by FM200 or Halon suppression systems, and the sponge is flame resistant. Clean rooms, labs, and data or equipment rooms with gaseous agents are the typical use, because the seal has to hold agent concentration during a discharge.
3) Is the NGP 127SDKB gasketing BHMA certified?
It is certified to ANSI/BHMA A156.22 for the heat and cold performance tests. That is the standard specifiers cite for door gasketing, so it satisfies a spec calling for A156.22 compliant perimeter seal on commercial openings.
4) What is the difference between the NGP 127SDKB sponge seal and the Cal-Royal PG-601 perimeter gasketing?
Both are aluminum channel perimeter gaskets that mount to the frame stop, but the sealing element differs. The NGP 127SDKB uses a closed cell sponge of synthetic rubber polymer siloxane with a patent pending microcellular silicone core, rated from -100 F to 500 F and BHMA certified to ANSI/BHMA A156.22 heat and cold performance tests, in an aluminum alloy 6063 T5 frame with a dark bronze finish. The Cal-Royal PG-601 is an aluminum channel perimeter gasketing that carries a vinyl insert. If the opening is a fire-rated assembly or a space using FM200 or Halon suppression, the silicone-core 127SDKB is the one built for that duty.
5) Does the NGP 127SDKB seal come with fasteners, or do I need to supply screws?
Screws are included. The 127SDKB ships with #6 x 3/4 inch stainless steel sheet metal screws, and the aluminum carrier is slotted so you can shift the seal in or out against the door face before final tightening. That slot adjustment is what lets you tune compression on a door that is slightly out of square.
6) What is the 127SDKB actually made of, and will it stand up to sun and weather on an exterior door?
The carrier is 6063 T5 temper aluminum and the seal is a synthetic rubber polymer siloxane closed cell sponge. Closed cell means it does not wick water, and the material resists ozone, UV, and aging, so it is suited to exterior entrances as well as interior environmental separations.
7) Can I use the Cal-Royal PG-601 instead of the NGP 127SDKB on a high-heat or cold-storage opening?
For openings that see temperature extremes, stay with the NGP 127SDKB. Its closed cell silicone sponge is rated to remain flexible from -100 F to 500 F and is BHMA certified to ANSI/BHMA A156.22 performance tests for heat and cold, with resistance to ozone, UV, and aging. The Cal-Royal PG-601 is an aluminum channel perimeter gasket with a vinyl insert, a general-purpose seal for standard interior and entry openings. Match the gasket to the environment rather than to the channel profile.
8) I need perimeter gasketing to match dark bronze frames - how do the NGP 127SDKB and Cal-Royal PG-601 compare on appearance?
The NGP 127SDKB is supplied with a dark bronze aluminum frame, so it reads as a finished trim line against bronze anodized or dark painted frames, and it comes in 36 inch, 72 inch, and 84 inch lengths so a head and two jambs can be cut from stock. The Cal-Royal PG-601 is an aluminum channel perimeter gasket with a vinyl insert. For a fleet of doors where the gasket should disappear into a bronze frame, the 127SDKB is the direct choice.
9) Is the Cal-Royal PG-601 a door bottom replacement for the NGP 127SDKB?
No - neither one seals the bottom of the door. The NGP 127SDKB is perimeter gasketing that mounts to the head and jambs of the frame with slotted screw holes and #6 x 3/4 inch stainless steel sheet metal screws. The Cal-Royal PG-601 is also aluminum channel perimeter gasketing. To close the gap at the sill you still need a separate door shoe, sweep, or automatic door bottom in addition to whichever perimeter seal you specify.
10) Will dark bronze gasketing match the rest of my door hardware?
The 127SDKB carries a dark bronze aluminum frame, which lines up with dark bronze storefront, hollow metal frames, and oil rubbed or dark bronze trim. For property managers standardizing a building, the same seal profile in a single finish keeps every opening looking alike across a floor.
