Replacement windows in Glastonbury, Hartford & Farmington include energy efficient options

Upgrading your windows will improve your home's efficiency and comfort.

Modern window glass has allowed replacement windows to become a key part of home efficiency. By choosing windows with low-E glass or argon filled glass, you can ensure your home has the most efficient windows available.

Low-emissive, or Low-E, window glass is manufactured with an invisible metal or metallic oxide coating to create a surface that reflects heat, while allowing light to pass through. Low-E windows are proven to increase energy efficiency, decrease fading of fabrics, and increase the overall comfort in your home.

Argon filled glass is another option. Argon is a non-toxic, odorless gas that is used in glass windows to prevent condensation and frost from forming on the window and provide improved soundproofing. Argon gas is filled between the panes of glass in a sealed unit to increase energy efficiency.

All ENERGY STAR windows feature a label with energy performance ratings from the National Fenestration Rating Council (NFRC). The label tells homeowners and contractors about how much heat and light travels through the windows through the U-value, solar heat gain coefficient, and visible transmittance of the windows.
