Composite Wood


Interior doors are often made of a composite wood core covered with a laminate or wood veneer. Doors made with engineered wood are cheaper than solid wood doors, but may pose indoor air quality problems from emissions in the binders or adhesives. Greener engineered wood alternatives include formaldehyde-free door cores, those that are made of recycled content or made from agricultural waste, such as wheat straw. Additionally, veneers may be made of sustainably grown and harvested wood. These greener alternatives must be explicitly specified, as they are not standard materials.
