Every ENERGY STAR® qualified window, door, and skylight is independently tested and certified to perform at levels that meet or exceed strict energy efficiency criteria set by the U.S. Environmental Protection Agency (EPA).
FiberFrame windows ordered with specific insulated glass packages meet and/or exceed these performance targets.
ENERGY STAR® requirements for windows and doors vary by climate zone. Therefore, FiberFrame builds its replacement windows and doors based on the ENERGY STAR® required specifications for the geographic region specified. Your representative will know exactly what combination you need for your location.
Add Comfort
Put an end to drafty windows in the winter, and steamy interiors in the summer. With FiberFrame fiberglass windows and doors that meet ENERGY STAR® guidelines, a room's interior environment stays comfortable all year round. Interior glass stays warmer in the colder months, while heat gain is reduced in the warmer months.
Reduce Costs
ENERGY STAR® qualified windows and doors can save up to 7-24% on energy costs, depending on the building size and location, as compared to non-qualified products. Save money, use less energy, and reduce the impact on the environment with FiberFrame.
Protect Valuables
As an added benefit, ENERGY STAR® qualified glass protects furniture, art, and other valuables from the fading and discoloring. The glass coatings act like a sunscreen and protect the room's interior from harmful ultraviolet light.
