The continual rise in solid lumber prices is due both to the inevitable depletion of timberland, and to the lumber industry’s reaction against increasingly stringent environmental laws. To the consumer this means only one thing: Homes built of conventional solid-sawn lumber will be getting a lot more expensive.
I-joists are stronger and straighter then solid wood floor joists, but can still be installed using regular wood framing methods. |
• Engineered lumber, which includes glued-laminated members, composite I-joists, and reconstituted wood members made of shredded wood fibers bonded by special glues. Unlike solid lumber, which inevitably has natural flaws such as knots and splits, engineered lumber has a consistent composition and hence a higher strength. This consistency also minimizes warping, which in solid lumber is caused by the tree’s natural growth rings.
Disadvantages of engineered lumber include a higher cost than solid lumber, heavier weight in some cases, and slightly more complex installation methods. However, many framers agree that the straightness and consistency of these member generally outweigh such problems.
Metal stud framing is also stronger and straighter than solid lumber framing, but working with it takes some getting used to. |
The drawbacks of steel framing have been its cost, which in past years was substantially higher than wood, as well as the need to re-train framers accustomed to working with wood. As steel framing becomes more prevalent, however, framers will become more comfortable working with it.
Concrete block can do most anything that wood studs can do, and will last longer. If you're used to building with wood, however, it's a whole new universe to work in. |
Today, however, concrete block is available in a range of styles and colors, and many interesting designs are possible. It’s the ideal material for passive-solar homes requiring thermal mass for heat storage. And when properly reinforced, concrete block is also seismically sound.
With old-growth solid lumber fast disappearing and managed forests producing lumber of generally inferior quality, the price of solid lumber will only increase in the future. If you’re thinking of building a home, alternatives to solid lumber are worth looking into.
