Cypress lumber is a softwood lumber species native to North America and is known for its natural durability, dimensional stability, and workability. It is naturally resistant to decay and rot, making it ideal for use in exterior applications. Cypress heartwood contains high levels of natural oils and resins, which help to protect the wood from moisture and insect damage.
The sapwood is pale yellow white with the heartwood varying in color from light to dark or reddish brown.
Cypress machines well, planes easily and resists warping. Pre-boring at board edges will help prevent splitting. It nails and screws very well. It glues well, sands easily and readily accepts finishes.
Cypress trees are conifers, but unlike most American softwoods, these are deciduous trees that shed foliage in the fall like hardwoods. Although cypress is a softwood, it grows alongside hardwoods and traditionally has been grouped and manufactured with hardwoods. The oils in cypress' heartwood make it one of the most durable woods when exposed to moisture conditions causing decay.

ROUGH CUT LUMBER
Rough cut lumber comes straight from the mill through the dry kiln in the form of planks. This is a version of lumber that has been kiln dried with no further processing.
SURFACE 2 SIDES (S2S)
Surfaced Two Sides (S2S) is rough lumber that has been dressed on the top and bottom of the board in order to meet the requested thickness. Associated Hardwoods has state-of-the-art planers that dress the boards to meet the customer's exact specifications.
Rip-To-Width lumber is where both sides of the board are ripped to a customer's specified width after surfacing.
Rip-To-Width/Cut-To-Length is where the board is manufactured and defected to a customer's unique specifications.
Glued-To-Spec is where boards are ripped & cut and glued into a panels.
NHLA Grading Rules
The NHLA grades are based on the percentage of clear-defect free wood on a board. The measurements of this percentage are referred to as clear-cuttings.
Other than the FAS grades, the grade of the board is determined from the percentage of these clear cuttings and do not consider defects outside of the clear areas.
