Quarter Sawn

Wood that has been cut from a log quartered lengthwise and at an angle of at least 45 degrees between the board face and the annular growth rings. This method of cutting lessens the warpage and shrinkage of the lumber. Radiant heating systems under hardwood should use a quarter sawn selection or a species of hardwood that is resistant to warping and cupping. Plain sawn is the other common cut of hardwood used for flooring yet is not as resistant to warping like a quarter sawn variety.
