Helpful Information

Environmental Data

As encapsulated door core materials, neither Fiberglass nor Cotton Batt pose health hazards or emit toxic gases. Cotton Batt insulation is made from 100% recycled materials that are bio-degradable and recyclable. During fire, no toxic gasses are produced by either material, and both are classified as fire retardant.

All resins and bonding agents utilized in fabrication are low VOC / environmentally friendly. The long life cycle and recyclability of stainless steel creates a truly sustainable product. See LEED Information.
