Using Reclaimed Lumber
Using reclaimed, also called recycled lumber is becoming popular. One of the reasons that its use is growing in popularity is that this is lumber that is salvaged from old buildings which was made from old-growth trees, and is typically stronger than fresh lumber. This lumber is also denser and has straighter grains than fresh lumber.
It's much better for the environment to reclaim old lumber, as discarding it releases carbon dioxide into the air.
There's no real improvement in the energy-efficiency of a home that has been built or remodeled with reclaimed lumber. Reclaimed timber beams can be beneficial when used to support a structure. The old beams are stable and should remain true, since any warping or shrinking happened decades ago.
There is much hand labor involved with deconstructing an old building, removing any screws or nails, then storing it and milling it into shape. Thus, reclaimed lumber is often more expensive than new lumber.
If you want to be sure of the reclaimed wood that you'd like to use in your project, work with a reputable reclaimed-lumber dealer, or directly with the lumber mill.
It's easy to pick out reclaimed lumber if you are experienced in the field, but most homeowners could be fooled into buying low-cost new lumber as reclaimed wood.
A good deal of reclaimed lumber comes from old factories, water towers, warehouses and barns. The reclaimed timbers have nail and screw holes many times, and can also have rust stains which give the wood a lot of character when used for exposed timbers in indoor areas.
Using reclaimed timber beams in combination with foam-core exterior panels can make a structure extremely energy-efficient.
