Lumber
Framing Lumber
- -#2 & better Fir and Larch: Nicest of all the framing lumber, it will accept longer times of unsupported framing before twisting.
- The WWPA puts it this way:
- "This species combination has the highest modulus of elasticity (MOE or E) value (the stiffness factor in floor systems) of all North American softwoods. In strength properties, DF-L has the highest ratings of any Western softwood for fiber stress in bending, tension parallel to grain, horizontal shear, compression perpendicular and compression parallel to grain." (species & end uses)
-
- -Hem-Fir: A hemlock and fir mixture that makes code at least in Washington State for most applications, if in doubt, ask your inspector or use Fir-larch combination.
-
- -Engineered Lumber: With this wafer product you will have a consistent stud width and depth. Cuts time on cabinet installation to the extreme! You will have the full inch and a half width to secure your sheeting or drywall into as opposed to regular framing lumbers 3/4".
Sheeting
- Most sheeting is associated with wafer wood or oriented strand board (OSB); it is all the same thing. But some include Plywood into this, so…
- ACX is the type of plywood that has an "A" side, which is sanded smooth and free from defects, and a "C" side, which is rough and can have defects. The "X" stands for exterior, likewise "I" would stand for interior (as in ABI normally stated as just AB) shop is a type that is just sanded and can have defects on the surface. A2 means that the plywood has an A surface on top and a #2 side on the reverse (associated with hardwood plywood).
- Now, hardwood is classified slightly different. It has to be clear in appearance to have a 1 rating, and a 3 can have surface defects.
