Weyerhaeuser brand hardboard siding is an exterior composite wood siding made from wood fiber mixed primarily with resin and wax and pressed under extreme pressure and heat into dense panels. Using different plate designs, these panels can have different textures. The panels can then be cut into long horizontal lap siding, or into sheets to make panel siding.

Most Weyerhaeuser hardboard siding is designed with a cedar wood-grain texture. Other textures include a stucco texture, smooth lap siding, a cedar shake texture or a cross-sawn wood texture. Since these textures are very realistic, it can be difficult to tell them apart from other kinds of siding.

There may be repeating features such as knots spaced 61" apart, or a "double knot" feature with two non-identical knots spaced 12 1/8" apart. If you can see the back, most styles contain the marking "AHA 10" or "AHA 20".
