Plywood that looks nice, in a species such as cherry, oak or walnut, is graded and priced mainly on the quality and thickness of the face veneer. Hardwood plywood is considered to be an appearance product, as opposed to softwood plywood, which is considered a structural material.
Hardwood plywood can cost about as much as an equal quantity of solid hardwood, depending on grade and appearance. But plywood has many advantages: •Dimensional stability. Crossbanded layers and balanced construction mean that hardwood plywood won't shrink, swell, or warp as much as lumber.
Marine-grade plywood, often simply called marine plywood, is not what it's often claimed to be. That is, it's not waterproof. And more to the point for everyday outdoor projects, it's also not rot-resistant. What marine plywood really is is a good-quality, hardwood plywood made with waterproof glue.
MDF is commonly used for shelving in closets and cabinets because it’s inexpensive and smooth. When I use MDF shelving for heavy loads, I simply beef it up with wood. Although medium-density fiberboard furniture isn’t of the same quality as solid wood furniture, it is cost-effective, often environmentally friendly, and incredibly durable.
Particle Board, MDF & Plywood Grades The primary differences between grades are the number of knot holes and voids. The amount of defects and work to repair them determines the grade. The type or grade of adhesive also has a part in grading. One of the best ways to find out about the grade is to look for a stamp that says "APA The Engineered Wood Association." This stamp will give you an A, B, C, or D grade based on the intended use of the panel.
