Fire-rated wall identification isn't optional — it's a legal requirement on virtually every commercial and multifamily construction project in the United States. NFPA 5000 requires permanent markings with lettering at least 3 inches in height and a 3/8-inch stroke in a contrasting color to identify the wall type. Stencil Ease The International Building Code reinforces this: markings must be placed within 15 feet of each wall end and repeated at intervals not exceeding 30 feet measured horizontally along the wall or partition.

StencilEase fire barrier stencils are built for exactly this job. Whether you're marking a Smoke Barrier, Fire Barrier, or Fire Wall — and whether your jurisdiction calls for 1-hour, 2-hour, or 3-hour rated designations — our stencils give your crew a fast, permanent, inspection-ready result every time.
Why contractors and facility managers choose StencilEase:
Code-grounded from the start. Our standard stencil wording aligns with NFPA 5000 and IBC Section 703.5 requirements. Available in 3-inch letter height (the NFPA-recommended minimum) and 4-inch for jurisdictions or inspectors that require larger lettering.
Built for the job site. Laser-cut from 10 mil Mylar, our stencils are durable, flexible, and rated for hundreds of uses Stencil Ease — light enough to carry in a tool bag, tough enough for concrete, wood, metal, and drywall. Pair them with our repositionable adhesive spray or ink roller system for a clean, mess-free application you can replicate every 30 feet down the wall run.
Every wall type covered. Our collection includes the three primary rated wall categories required across U.S. building codes: Smoke Barrier, Fire Barrier, and Fire Wall — with hour-rating variants so your marking matches exactly what the engineer of record specified.
Custom when the code isn't standard. Fire districts and local AHJs (Authorities Having Jurisdiction) don't always use the same verbiage. Some require specific phrasing, additional rating language, or non-standard letter sizes. Our custom stencil service handles all of it — submit your exact wording and specs, and we'll cut it to order.
