Engineered Wood Products
Previously, I did a little post about lumber, the cheapest and lowest quality control option in for structure. Moving up the ladder a bit, there are engineered wood products which have several advantages over traditional lumber, but generally cost more. Engineered products are typically stronger, more dimensionally stable, and less prone to warping and twisting and most houses generally have at least a few engineered components. In general, they cost in line with a steel beam, material wise, but are often much easier to install being either lighter or capable of being put together in place.
