Wood is a renewable material.
It requires less energy to produce than alternative building products. CCA preservative is made in part from recycled ingredients. The treating process releases no air pollutants nor wastewater. Wood construction often allows the use of lower impact installation equipment than does construction with heavier building products. Through the use of wood preservatives in pressure- treated lumber for fences, porches, decks, and homes, we have saved a forest of trees two times the size of New England.
