We buy from the best Douglas Fir Mills to get the best lumber for you! All our fir lumber comes from mills that produce premium products. There are other fir products available in our area from mills that don’t meet our quality standards. • Our 1” boards are C & Better grade. They are a flat grained, kiln-dried product. • Our 2” dimension is C & Better grade. They are a mixed grained, kiln-dried product, which generally contains only about 10% vertical grain. • Our 5/8”x4” beaded ceiling is a C & Better grade, flat grained, kiln-dried product. • Our 1x4 T&G flooring is all C & Better, Vertical Grain, kiln-dried. • What is Vertical Grain? (Also referred to as Quarter-sawn) It is when the growth rings in the board are perpendicular to the width of the board. Vertical Grain is far superior to flat grained products when used for walking surfaces. • If painted, it needs to be primed, before installation, on ALL sides, ends and edges. • The mill we buy this product from manufactures some of the highest quality flooring available. The raw wood fiber they use is harvested from one of the best timber growing areas, plus they grade on the high side of the C & Btr. grade. • 5/4x12 Nosed Stepping is all C & Better, Vertical Grain, kiln-dried. • What is Vertical Grain? (Also referred to as Quarter-sawn) It is when the growth rings in the board are perpendicular to the width of the board. Vertical Grain is far superior to flat grained products when used for walking surfaces. • This stepping comes from the same mill and wood fiber as our other fir products, so the quality is top-of-the-line. • REMEMBER that even though C & Better is the highest grade commonly available, this grade allows some defects such as pitch pockets and small knots in occasional pieces. It is not “Clear” as some people assume. All of our C & Btr. Fir lumber is kiln dried to 12% or less. The moisture content typically runs around 8%.
