LP 29915 Operating instructions

Brand: LP

Model: 29915

Type: Operating instructions

LP 29915 is a versatile and durable oriented strand board (OSB) panel with a fire-resistant coating, designed for use in roof, wall, and subfloor systems. It offers superior fire protection, meeting the requirements of a Class A Flame Spread Rated material. With its strong and stiff structure, LP 29915 provides excellent racking strength, making it suitable for corner bracing applications. The panels are easy to install, requiring conventional nailing techniques, and can be sawn, routed, or drilled using standard woodworking tools.
