Quartersawn (vertical grain) is the better choice, although it is more expensive. Quartersawn lumber is cut from the tree so that the growth rings are perpendicular to the face of the board. Thus, when seen in cross-section, a quartersawn board will appear to have a series of short parallel lines from top to bottom of the board. In flat-sewn (plain-sawn) siding, the growth rings are tangential to the face of the board, appearing as curved lines. Generally, quartersawn lumber shrinks in width half as much as flat-sawn material as it cures, making it less likely to change shape after installation.
Do you have any questions about which sort of lumber is best for your project? If so, you can ask our expert staff members to explain the pros and cons of both flat-sawn and quartersawn lumber. We'll be happy to explain the pros and cons of each sort and ehlp you decide if the higher quality is worth the extra money. In addition, we have an extensive paint selection, for putting the finishing touches on your project. Call 410-257-2963 for Owings location or 410-326-3222 for our Lusby location if you have any questions.
HINT: Quartersawn siding is less likely than flat-sawn siding to cause nail pops and is more likely to hold paint better (because it is dimensionally more stable).
