Ensuring Your Comfort, Safety and Peace of Mind
Four Seasons Sunrooms components pass rigorous independent testing and are then approved or qualified by these major independent accreditation agencies.

Four Seasons Windows and Doors are tested, certified and/or qualified by not one, but three, independent agencies and programs: the National Fenestration Ratings Council (NFRC), the American Architectural Manufacturing Association (AAMA) and ENERGY STAR®. These groups certify all the major window and door manufacturers products. Before you buy windows for your home, ensure they are NFRC and AAMA certified and ENERGY STAR qualified. We encourage you to check these agencies' websites and review our accreditations (we're listed under Four Seasons Solar Products).

ENERGY STAR ENERGY STAR
ENERGY STAR is a government-backed program helping businesses and individuals protect the environment through superior energy efficiency. All Four Seasons products are ENERGY STAR qualified. ENERGY STAR qualified windows and doors do more than just lower energy bills – they deliver more comfort, create less condensation, and protect your valuables from sun damage better than conventional clear-glass double-paned alternatives. By lowering your energy use, these windows are also better for the environment: The less energy you use, the less air pollution power plants produce.

ENERGY STAR was created to help consumers easily identify products, homes, and buildings that save energy and money, and help protect the environment. As the government-backed, trusted symbol for energy efficiency, the ENERGY STAR label identifies highly efficient products and designates superior energy performance in homes and buildings.


Good Housekeeping Seal American Architectural Manufacturing Association (AAMA)
AAMA is the source of performance standards, product certification and educational programs for the window, door and skylight industry. For your peace of mind, Four Seasons Windows and Doors are labeled with a permanent gold label that is affixed to the window frame.



Good Housekeeping Seal National Fenestration Rating Council (NFRC)
NFRC is a non-profit organization that administers the only uniform, independent rating and labeling system for the energy performance of windows, doors, skylights and attachment products. Its goal is to provide fair, accurate and reliable energy performance ratings. A removable NFRC label is attached to every Four Seasons Window and Door.
