Fire-Rated Glazing & Opening Protective Components: Channel Liners, Intumescent Strip, Barrier Layers & Rated Perimeter Joints

No, and the distinction matters. H-O die-cuts, slits, laminates, and kits components that go into a listed fire-rated glazing or opening-protective assembly. The rating belongs to that tested assembly, evaluated under ASTM E119, NFPA 257, UL 9, or UL 10B/10C and installed per NFPA 80. It does not belong to any material in it, and no converter can confer or extend it by supplying a part.

H-O supplies the converted component to your drawing, the vendor TDS with its data lines, and lot-code traceability, under an ISO 9001:2015 certified quality management system. [1] [6]

It means the governing document for your opening is the listing, design number, or classification file, and specifically its material schedule, which names each component and the configuration tested. Your submittal has to show that the part in the frame is the part the schedule names. Where the schedule describes a component generically, you can offer a material against that description with the TDS to support it.

Where it names a product, grade, or thickness, a change goes to the listing agency in writing before the part is bought. A material catalog cannot override the schedule. [6]

No. UL 94 is a small-scale flammability classification for plastics, run on a defined specimen in a defined orientation with a defined burner, and V-0 is one of its classes. It belongs on the submittal with its method named. It is not a fire-resistance rating and does not substitute for the assembly test ASTM E119, NFPA 257, UL 9, or UL 10B/10C applies. A gasket published as UL 94 V-0 is a gasket with a V-0 data line, acceptable in a rated opening only where the listing's material schedule allows it. [12]

ASTM E119, with NFPA 251 as its long-standing companion, is the fire-resistance test method for building construction and materials: it exposes an assembly to a standard time-temperature curve and reports how long the assembly meets the acceptance criteria. NFPA 257 is the fire test standard for window and glass block assemblies, adding the hose-stream requirement.

Walls and floors are spoken about in E119 terms, rated window assemblies in NFPA 257 and UL 9 terms, door assemblies in UL 10B and UL 10C terms. All are assembly tests, not material properties. [1] [3]

UL 10B is the neutral-pressure fire test of door assemblies and UL 10C is the positive-pressure test; the difference is the furnace pressure condition, and positive pressure is the more demanding exposure current model codes generally reference for new work. Which applies is a code and authority-having-jurisdiction question, and the answer determines which listing you build to and therefore which schedule you buy against. Bring it with the RFQ; H-O converts what the resulting schedule names and does not decide which standard applies. [5] [6]

Read the grade's own published data. ManniGlas 1200 is published at 1200°F continuous service per the vendor TDS; the 2000 series at 1100°F continuous with a 1200°F excursion per the published data. Continuous service and excursion are different exposure conditions, and collapsing them into one number is how a data line turns into a claim the data sheet never made. Those figures describe the paper, not the opening, and the grade that belongs in your channel is the one the schedule names.

That depends on how the schedule names it, and it is not a purchasing decision. If the schedule describes the liner generically, by composition and nominal thickness, a converter can offer options with the TDS to support them. If it names a product, grade, or thickness, the opening as built has to match, and a change goes to the listing agency in writing first.

Getting this wrong is not a bench problem; it is an inspection or insurance-review problem years later. H-O flags whether a request reads as a like-for-like conversion or as a substitution the listing has to see. [6]

Enough for the expansion the named grade delivers to close the gap the design intends, which makes free volume a drawn dimension rather than a rule of thumb. Expansion ratio and activation range belong to the grade the listing names; free volume, standoff, and install compression belong to your drawing.

The quiet failure is over-compression at glazing: a strip squeezed well below nominal thickness has spent part of its expansion budget and nothing looks wrong. Control those three explicitly, and use die-cut shims where tolerance stack-up would otherwise decide them. [5]

NFPA 285 applies to the exterior wall assembly, not to your joint component, and that is the point of it. It is a standard fire test method for evaluating fire propagation characteristics of exterior wall assemblies containing combustible components, run on a multi-story test wall, qualifying the specific assembly layer by layer in the configuration tested. A component data sheet cannot inherit that result.

Combustible components inside the wall, including joint backing, insulation, and weather-resistive layers, are constrained by the qualified assembly rather than by their own TDS. Read the qualification report before specifying into the joint. [7]

They are two qualifications with two evidence trails, and one does not imply the other. Fire resistance and opening-protective performance come from ASTM E119, NFPA 257, UL 9, and UL 10B/10C. Smoke and draft control comes from UL 1784 air-leakage testing, with NFPA 105 addressing smoke door assemblies; material-level smoke behavior is measured separately by ASTM E662 or the smoke-developed index in ASTM E84.

The same door can carry both, but a fire test result is not evidence for the smoke designation. Read the schedule for both at the start and build both records. [8] [9]

Different scale, different question, different report. UL 94 burns a small specimen in a controlled orientation and returns a class such as V-0, V-1, or HB, a comparative flammability screen for plastics. ASTM E84 runs a specimen in a tunnel and returns flame-spread and smoke-developed indices, which is how surface burning characteristics of interior finishes are typically specified. ASTM E662 adds specific optical density of smoke from a chamber test.

All three are material data lines on the TDS. Cite whichever your specifier asked for, with the method named, and keep them separate from the assembly rating. [10] [11]

Yes, that is the core service. Send the drawing plus the schedule pages, and H-O converts the liner strip, mica or glass-fiber separators, aramid barrier layers, intumescent strip and corner pieces, blocks, and joint components to the drawn geometry: die-cut, slit, laminated, kiss-cut on liner, and kitted so the shop installs a set rather than sorting stock. Engineering reviews each item against the vendor TDS and the schedule and flags anything that reads as a substitution. What H-O will not do is tell you the resulting opening is rated.

H-O converts intumescent strip stock that a listing names, to the channel geometry your drawing shows, including corner pieces and kitted sets. H-O does not formulate or select intumescent chemistry, extrude or mold profiles in-house, supply wet sealants or sprayed and caulk-grade firestop, or design or certify a through-penetration firestop system under ASTM E814. Those are separate trades with their own listings. H-O adds the converted die-cut component, the TDS review against your schedule, and the traceability record that ships with the parts. [13]

On a rated program the deliverable is the part plus its record: the vendor's published technical data sheet on file for the material as supplied, the grade and thickness as shipped, a lot code tying the shipment to that material, and a certificate of conformance to the purchase order where the program calls for one. The package is produced under an ISO 9001:2015 certified quality management system; lot-specific documentation is available on request. Ask for it at RFQ so the record starts with the first shipment.

Every fire-program component is made-to-order to your drawing, including samples and prototypes. Most of these materials are commonly stocked or sourced on demand by H-O, subject to availability.

Typical prototype lead time is 5–10 business days after drawing review, depending on material availability, tooling, and inspection requirements, and 24 hours when the material is in-house. Standard production runs ship about 2 weeks after drawing approval. Expedited service is available. MOQ varies by material and part. Send the drawing, the schedule pages, and the quantity through the form below for a specific lead-time commitment.
