SYNERGY WOOD® FAQS

LUMBER GRADE 101

Even though each type of wood has its own grading system, the purpose of grading lumber is the same; a method to communicate between buyer and seller of what is and isn’t acceptable.

HOW SYNERGY WOOD GRADES LUMBER

The wood that enters our facility is fist graded using standardized grading at the lumber mills. Below is a list of the species and grading rules used by Synergy for our initial inspection of incoming lumber. The Synergy Wood Grading Guide is a basic description of what we typically accept for each type of wood we process.

Governing Grading Standards Used by Synergy:

SOUTHERN PINE: Southern Pine Inspection Bureau Grading Rules, 2014

During our production process, Synergy inspects each piece of lumber by hand. Wood is a natural product and therefore, each piece is going to be uniquely different.

The result of Synergy’s extra grading process is an easy to install product that reduces on-site installation waste to 5% or less.

Every board that is delivered to a job site is usable. See our guide “How To Use What’s Delivered” for more information.

E-PECK®: RED GRANDIS & SOUTHERN PINE #2
We developed E-Peck® to simulate old growth peck. This proprietary process was designed to have just the right amount of peck in each board. Our process creates a random pattern in each board - and over a series of boards.

What Synergy allows:
Similar to the #2 grade, E-Peck® will have unlimited surface checks and knot holes included. Lose knots or knot holes may have tape backing. In some applications, if the knot holes are undesirable, the installer can cut these areas out and create starting or ending boards. Check out our “How to Use What’s Delivered” guide.
Southern Pine: #2 GRADE
What Synergy allows:
- Manufacture - admits very heavy torn grain; raised grain; very heavy loosened grain; up to 1/16” deep machine bite; up to 1/16” deep machine gouge; up 1/16” deep chip marks; knife marks.
- Decay - in streaks of heart-center decay not to exceed 1/2” wide by 1/4 length of piece, or equivalent in unsound red heart.
- Holes - up to 1/4” not limited; one through hole over 1/4” but not over 1”; surface pits and cavities limited to 2” diameter in 6” wide board.
- Knots - sound, firm, encased, and pith, limited to 3” diameter in 6” wide board; all knots fixed or tight, except loose knots limited as through holes.
- Items not limited: Pitch, pith, shake, checks & splits.
