Sierra SB PURadria Collection By PurParket Flooring

Sierra SB sits in the SB grade, which in European White Oak comes in 7.8″ and 9.8″ widths. Wider boards mean fewer seams across a room, and the engineered build, a basswood filleted core with a matching backer, is what holds those widths flat over a concrete slab where solid wood would move. North American White Oak runs 5.5″, 7″ or 8.5″ in Select, with Red Oak at 6″. The face wears a PurFlex UV Oil coating, and the floor is backed by 35 years residential and 10 years light commercial cover. It is radiant heat compliant and accepts wood or concrete subfloors. 22FLOORING supplies and installs Sierra SB across Toronto and the GTA, with engineered hardwood installation from $4.90 per square foot, including glue and nails.
