A Leading Manufacturer of OSB Panels

Xmark is a leader in the production and marketing of OSB panels and lumber in Canada. Our company prioritizes sound renewable resource management and state-of-the-art technology to deliver exceptional products to our customers.

OSB's Strong Material Strength

Our oriented strand boards are composed of wood strands arranged in perpendicular layers and glued with exterior grade resin. While the internal strands ensure the board’s cohesion, the outer strands give it its excellent mechanical strength. OSB is perfect for sheathing. Its strength and durability also make it an ideal choice for subflooring.

Renewable Resources

Wood used in the OSB manufacturing process comes from renewable resources. Small, rapid growth trees are generally used and, unlike plywood, the entire tree is used during manufacturing. Residual materials are used for fuel production.
