Product overview
WISA®-SpruceFR is a fire-retardant spruce plywood panel designed for structural and load-bearing applications. The panel features an integrated fire-retardant treatment that enhances fire performance while retaining full structural properties.

Key benefits

• Fire-retardant performance: Meets B-s1, d0 and Bfl-s1 classifications for wood-based materials while maintaining structural capacity.
• Simplified approvals: Integrated solution can reduce separate fire protection approvals and streamline specification.
• Time and cost savings: Eliminates the need for additional coatings or multilayer fire solutions, simplifying storage, handling and installation.
• Sustainable material choice: Manufactured from renewable spruce, stores carbon during its lifecycle and supports documented environmental performance.

Performance & documentation
WISA®-SpruceFR fulfils the B-s1, d0 and Bfl-s1 fire classification and retains full structural performance. The fire-retardant formulation is free of halogenated compounds, heavy metals and boron. Comprehensive technical and environmental documentation is available, including CE marking, Declaration of Performance and an Environmental Product Declaration (EPD) to support specification, CO2 calculations and approvals.

Practical advantages
As an integrated fire-retardant plywood, WISA®-SpruceFR offers a cost-effective alternative to complex multilayer fire solutions. It simplifies material selection, quantity calculations, transport and on-site installation for builders, architects, engineers and distributors. A recent visual update gives the panels a red-toned appearance for easier on-site recognition.

Applications
Structural and load-bearing elements in building and construction where fire retardancy is required.
