Environmental Data

As encapsulated door cores, there exist no health hazards or toxic gas emissions. During fire, few, if any, toxic gasses are produced and door cores are rated as Class I fire retardant materials.

All resins and bonding agents utilized in fabrication are low VOC / environmentally friendly. The long life cycle of the steel doors makes them truly sustainable products. See LEED Information.
