Installing energy-efficient windows can reduce energy use and cut your monthly heating and cooling bills. The U.S. Department of Energy has determined that 30% or more of a home’s energy can be lost through inefficient windows. Can you afford to continue to waste up to one-third of the money you spend every month on utility bills?

Edmunds General Contracting installs replacement windows that are among the most efficient on the market, with superior energy performance engineered into the frames and glass.

How to Determine the Efficiency of Andover Replacement Windows

How can you tell if a window is energy-efficient? Standards have been established by the National Fenestration Rating Council (NFRC), an independent, non-profit organization that administers the only nationally accepted rating system to measure the energy performance of windows, doors and skylights. The NFRC provides fair, accurate and reliable energy performance ratings, allowing architects, builders, code officials, contractors and homeowners to compare products and make informed choices.

  • U-Value. The most important measure of a window’s performance is its U-value, the rate of heat flow through a window. The lower the U-value, the more energy-efficient the window will be. U-value measures the entire window unit and is the only measurement accepted by the U.S. Department of Energy’s ENERGY STAR program.
  • R-Value. R-value is the measure of the resistance of glass to the flow of heat. The higher the R-value, the better the glass will be at insulating your home. However, R-value is not an accepted form of measurement by the NFRC or ENERGY STAR, as it does not measure the overall window unit.
  • Solar Heat Gain Coefficient. Solar Heat Gain Coefficient (SHGC) measures how well a product blocks heat caused by sunlight. SHGC is expressed as a number between 0 and 1. The lower a window’s solar heat gain coefficient, the less solar heat it transmits.

Energy-Efficient Glass Reduces Monthly Utility Bills

The glass packages available in replacement windows installed by Edmunds General Contracting include some of the most advanced features available today. At the heart of our replacement windows is a technologically advanced glass called Low-E (low emissivity) glass. Low-E glass maximizes your home’s efficiency by reducing the amount of heat entering or escaping. Microscopically thin layers of oxidized metal are applied to the glass surface, allowing filtered light to pass through while reflecting most heat energy back to its source – an incredibly efficient way to reduce energy loss.
