Only one primary building material comes from a renewable resource: wood. As it grows, it cleans the air and water and provides habitat, scenic beauty, and opportunities for recreation. As part of a structure, wood’s natural insulating properties (many times higher than steel or concrete) reduce the energy required to heat and cool the structure for its lifetime. Wood is reusable, easily recycled, and 100% biodegradable. In addition to the great environmental benefits associated with wood, glulam timbers extend the available wood resource by using high-grade material only where it is needed in the layup. Glulam technology also uses small-dimension lumber to make large structural timbers, utilizing logs from 2nd and 3rd-growth forests and timber plantations. As a green building material, structurally glued laminated timber simply can’t be beat.
