Plywood is chemically pressure-treated to reduce the spread of flames and generation of smoke. In the event of a fire, this plywood will not spread fire and develops less smoke. Plywood may be substituted for materials classified as non-combustible in certain building types designed by the model building codes. This plywood can be painted or stained just as untreated wood, but flammability of the finish should be considered. This plywood is in intended for interior use only and should be protected against direct moisture, precipitation or regular condensation. This plywood is low-corrosivity, non-blooming and low-hygroscopicity. Plywood has No VOC’s or Formaldehyde. Galvanized steel hardware is recommended, although the D-Blaze treatment does not increase the corrosion of bare steel. Ripping or cross-cutting plywood, drilling holes and light sanding is permissible. It is not necessary to field-treat cut ends to maintain the flames spread rating.
