Tolko Industries re-engineered its T-Grade oriented strand board flooring to better resist moisture and warping, deflect less when walked on, and offer greater shear strength. The panels are skip-sanded for an even surface and snug tongue-and-groove fit. Edge-coated in a recognizable blue sealant, the panels are priced competitively and carry a 25-year limited warranty, Tolko says. 250.545.4411.
