Quartersawn Clapboards
Quartersawn Clapboards
This milling procedure leaves a straight, vertical grain which minimizes cupping, warping and twisting. Quartersawing exposes the maximum number of grain surfaces, which act like capillaries to better absorb paint andstain.
Time Tested
Our clapboards are kiln and air dried by alternately layering uniform diameter clapboards into six foot by six foot stacks until dried to a 12% moisture content.
Clapboards are planed and edged on one side. The ends are squared and clapboards graded as follows:
1 X Clear: Clear unmarked on exposed section of clapboard.
2 X Clear: Up to one knot or blemish on exposed section of clapboard.
Rustic: Clapboards are graded on the rough circular sawn side and are essentially clear.
Sizes: All clapboards are milled to 7/16″ thick at the bottom.
6″ clapboard graded to 4″ exposure.
5 1/2″clapboard graded to 3 1/2″ exposure.
5″ clapboard graded to 3″ exposure.
4 1/2″clapboard graded to 2 1/2″ exposure.
Packaging: Clapboards are sorted by length and grade and strapped into bundles. They are then stacked and palletized. The pallets have bundles of boards varying in length from 2′ to 6′. The majority of boards will be longer lengths.

Leaning dutifully against a wall in the mill office is a clapboard stamped with the Granville Mill’s logo of over 100 years ago. It was found on a house in Boston that was to be torn down and is still as straight and true as the day it was sawed.
