Feather River fiberglass doors have an environmentally friendly CFC free polyurethane foam core that provides five times the insulation value of wood doors. Our foam compression weather strip and reversible double-bulb four fin sweep combined with our adjustable high dam threshold provide superior protection against air and water filtration. All Feather River 6' 8" fiberglass doors and sidelites with our triple pane decorative glass have been awarded the ENERGY STAR for all 50 states. ENERGY STAR is a government backed program sponsored by the U.S. Department of Energy and the U.S. Environmental Protection Agency that helps consumers identify products that save energy and help protect the environment. ENERGY STAR requirements vary for doors by climate zone. Ask for doors that are ENERGY STAR qualified in your climate zone. |
