A strong 2025 list will feature North American leaders (often seen in framing and subfloor markets) alongside major European groups with large OSB footprints.
Expect names like West Fraser (formerly Norbord), LP Building Solutions, Georgia-Pacific, Weyerhaeuser, and Huber Engineered Woods in North America, and Kronospan, EGGER, SWISS KRONO, and MEDITE SMARTPLY in Europe—plus regional standouts serving Latin America and Asia.
When comparing suppliers, look beyond capacity: check panel grade (OSB/3 or OSB/4 where needed), third-party certification (APA/CE), moisture performance features (edge sealing, textured faces, integrated WRB), warranty terms, and local availability to reduce lead times and freight.
