OSB stands for Oriented Strand Board. It is an engineered material that is great for load-bearing applications. An alternative to plywood, it is constructed to prevent warping and splitting. Commonly used in sheathing on walls, floors, and roof decking.
A sanded plywood panel with A-grade face, C-grade back and C-grade inner plies bonded with exterior glue. Our AC is solid core for use as underlayment.
Structural plywood used for sheathing surfaces of a building prior to being covered with other materials such as flooring, siding, or roofing. C/D grade indicates that the face has knots and defects filled in while the reverse side may have some that aren’t filled in. Neither side has been sanded smooth or appearance grade.MCA stands for Micronized Copper Azole.
MCA is a copper-based wood preservative used in pressure treated lumber allowing for residential installations above ground, ground contact, or freshwater contact. Lumber pressure treated with MCA can be used in interior applications as long as all construction debris, including sawdust, is collected and disposed. Do not use in instances where the lumber could come in contact with food or animal feed. To keep the integrity of the pressure treatment, coat all cuts and holes which expose untreated wood with an end-cut preservative before installation.
Drywall panels are factory-fabricated, composed of a fire-resistant gypsum core encased in heavy natural-finish face paper and strong liner paper on the back. The face paper is folded around the long edges to reinforce and protect the core. The ends are square-cut and finished smooth. Long edges of panels are tapered allowing joints to be reinforced and concealed with a USG joint treatment system.
