NASHVILLE, Tenn.--(BUSINESS WIRE)--Mar. 3, 2026-- LP Building Solutions (LP), a leading manufacturer of high-performance building products, today announced the launch of LP BurnGuard^™ Fire-Retardant-Treated (FRT) Oriented Strand Board (OSB), the first commercialized fire-retardant-treated OSB certified to meet the International Building Code (IBC) and International Residential Code (IRC) definitions for FRT wood structural panels.

The first commercialized FRT OSB certified to meet IBC and IRC definitions, featuring fully integrated fire-retardant protection

The new panel expands LP’s portfolio of fire-rated solutions, reinforcing the company’s long-term product innovation strategy and commitment to helping builders meet evolving code requirements. Designed for multifamily and other fire-rated applications, LP BurnGuard FRT OSB features fire-retardant protection fully integrated throughout the panel.

The treatment is blended directly onto the wood strands before forming and pressing, delivering consistent performance through the entire thickness of the panel. Since the protection is built into the panel itself, LP BurnGuard FRT OSB installs in the same manner as standard OSB sheathing, allowing builders to meet fire-resistance requirements without changing installation methods or workflow.

LP BurnGuard FRT OSB has already earned industry recognition, including designation as a Building Design + Construction Top 75 Building Product and finalist honors in the NAHB International Builders’ Show^® Best of IBS^™ Awards this last February.

Manufactured entirely in-house at LP facilities, the product carries a single LP-backed limited warranty. Unlike pressure-treated fire-retardant panels finished by third parties, LP BurnGuard FRT OSB incorporates the treatment during the manufacturing process. This proprietary technology developed by LP is patent pending.

“LP BurnGuard FRT OSB represents a major step forward in how the industry approaches fire‑retardant structural panels,” said LP CEO Jason Ringblom. “By integrating the fire‑retardant treatment throughout every strand, we’re delivering consistency, reliability and ease of installation. This product gives builders the confidence to meet today’s demanding codes without sacrificing speed or performance. That’s exactly the kind of innovation LP is committed to bringing to the market.”

Engineered for versatility, the 4 by 8 foot panels are approved as APA Rated Sheathing in both 7/16 and 15/32 performance categories. The 7/16 panel carries a Wall‑24 span rating and maintains full shear wall capacity for wall‑only applications. The 15/32 panel supports wall applications without reduction and roof sheathing applications with a 24/16 span rating, expanding structural options for builders.

LP BurnGuard FRT OSB is approved for exterior walls of Type III construction, nonbearing partitions and nonbearing exterior walls in Type I and II construction. It is also approved for other interior applications for which FRT wood sheathing is permitted by building code. The panel is designed to complement other LP fire‑rated offerings, including LP^® FlameBlock^® Fire-Rated Sheathing.
