Did you know? More Wood is used each year in the USA than ALL cement, steel and plastics COMBINED! Plus, wood uses the least amount of energy to manufacture. For example, the manufacture of aluminum siding requires 5 times more energy than wood siding. A steel wall requires 3 to 6 times more energy to extract, manufacture and construct than a wood wall. It takes 21 times more energy to produce the materials for a 4" thick raised concrete slab floor than a raised wood floor? By using wood in all types of building applications, we can save energy and help conserve our limited energy resources.
