Rift and Quartered White Oak flooring is extremely stable due to the orientation of the wood grain. Because Rift and Quartered White Oak’s grain is oriented from 80-90-degrees in relation to the plank, lateral or side to side movement, is minimized. Essentially, it shrinks and expands only in its thickness.
The “Cathedral” grain peaks are virtually eliminated, but in the case of Rift and Quartered White Oak, the “fleck” patterns of the Medullary rays are profound.
Rift and Quartered White Oak is superior in hardness, dimensional-stability and moisture penetration versus plain-sawn. It is generally the only approved domestic solid hardwood approved for radiant floor heating systems.
