Sanded plywood panels are structural panels with face and back plies that are sanded smooth in the manufacturing process.
Touch-sanded panels are plywood panels “sized” to uniform thickness by light surface sanding during manufacture. Sander skips are admissible.
A ply is single veneer in a panel. In plywood, a layer consists of one or more adjacent plies having the wood grain in the same direction. For instance, four-ply panels always have three layers with both core plies at right angles to the faces. The two core plies are one layer and each face is a layer. In OSB panels, the reconstituted wood portion is one layer and each face is a layer.
Yes, in fact APA member products have such low emission levels that they are exempt from the leading formaldehyde emission standards and regulations. APA Technical Note: Formaldehyde and Engineered Wood Products, Form J330, addresses the concerns about formaldehyde related to plywood and OSB wood structural panels and explains why plywood and OSB manufactured to U.S. Product Standards PS 1 and PS 2 are exempt.
In the applications for which they are manufactured, the two products are virtually interchangeable. Although different in composition and appearance, plywood and OSB are manufactured according to the same performance standard criteria. Which product you choose will depend on your requirements for a variety of characteristics including finished size, surface quality and panel density.
Marine grade plywood is a specially designed panel made entirely of Douglas-fir or Western Larch. The grade of all plies of veneer is B or better, which means it may have knots, but no knotholes. The panels are sanded on both faces, and are also available with Medium Density Overlay (MDO) or High Density Overlay (HDO) faces. The maximum core-gap size permitted is 1/8 inch. Its exposure durability rating is Exterior and the glue used is a moisture-resistant structural adhesive. It is considered a “premium” panel grade for use in situations where these characteristics are required, i.e., for boat hulls and other marine applications where bending is involved. Marine-grade plywood is available in 4x8-foot sheets of 1/4, 3/8, 1/2, 5/8 and 3/4-inch thickness. Sheets up to 5x12 feet are also available. Available grades are A-A, A-B, B-B (face-back), MDO and HDO. Marine-grade plywood is not treated with any chemicals to enhance its resistance to decay. If decay is a concern, it should be pressure-preservative treated to an appropriate standard. The detailed description of veneer grades and Marine grade plywood is contained in Voluntary Product Standard PS 1, Structural Plywood.
