Spruce FireResist - Fire treated plywood for interior panelling

Metsä Wood Spruce FireResist is a surface impregnated softwood plywood panel with enhanced fire performance. Spruce FireResist fire treated plywood remains visually and physically stable in interior applications where wetting does not occur. Suitable applications for the fire treated plywood are interior applications in service class 1 (EN 1995-1-1). Spruce FireResist does not contain heavy metals, boron or halogenated compounds.

The fire treated plywood product contains nothing classified as hazardous waste and the product is classified as biofuel. Additional coatings are not recommended for Metsä Wood Spruce FireResist as coatings might affect the fire performance of the plywood. The compatibility of the surface treatment should be confirmed from the paint or varnish supplier. Chemical composition of fire retardant additives is selected from a safety perspective. Only halogen-free and heavy metal-free additives are used in the formula.
