Exterior Fire-X™ (XFX) Lumber & Plywood

Exterior Fire-X™ (XFX) is pressure-impregnated fire-retardant lumber and plywood that provides comprehensive fire protection for projects that will likely be exposed to hot outside weather, as well as other humid environments. Exterior Fire-X™ (XFX) can be used outdoors and indoors, and offers the workability of wood with the fire-safety benefits of non-combustible materials. We offer Exterior Fire-X™ (XFX) in sizes from 2×4’ to 6×16’, as well as 5/4×6 Radius Edge Decking, and Rated Sheathing plywood in several sizes.

Exterior Fire-X™ BLUE Lumber & Plywood

Exterior Fire-X™ BLUE is color coded with a pressure-applied blue stain for easy identification, with the same fire performance characteristics as Exterior Fire-X™. Exterior Fire-X™ BLUE is widely specified by government agencies and is often used in the nuclear construction and ship-building industries.

Micro-Guard™ Lumber & Plywood

Micro-Guard™ lumber and plywood is pressure-treated wood that protects against corrosion, termites and fungal decay. Furthermore, we only offer Micro-Guard™ Treated Lumber and Plywood that has been Kiln Dried After Treatment (KDAT) to ensure that all products are brought down to workable moisture levels. This prevents moisture-related problems from occurring in the future, such as warping and twisting in lumber, or buckling or crowning in installed plywood projects. We offer Micro-Guard™ in sizes from 2×4’ to 8×20’, as well as 5/4×12 Nosed Stepping.
