Installing energy-efficient windows from Family First Construction in your home can help cut energy use and reduce 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 waste almost one-third of the money you spend every month on heating and cooling your home?

Family First Construction installs replacement windows that are among the most efficient on the market, with superior energy performance engineered into the frames, glass and overall Minneapolis windows.


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

The most important measure of a window’s performance is its U-value. The U-value indicates 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 — glass, frame, sash, spacers — and is the only measurement accepted by the U.S. Department of Energy’s EnergyStar program.

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. But R-value is NOT an accepted form of measurement by the National Fenestration Research Council (NFRC) or EnergyStar, as it does not measure the overall window unit.

Look for the NFRC label on any replacement window Minneapolis you purchase.


The glass packages available in replacement windows installed by Family First Construction include some of the most advanced features available today. The heart of our replacement windows is a technologically advanced glass called “Low-E “glass.

Low-E Glass maximizes your home’s energy efficiency by reducing the amount of heat entering or escaping. Low-E (“low emissivity”) Glass has a thin layer of oxidized metal on one side, which greatly enhances the glass insulating properties. Heat and light are allowed to enter, but the thin metal sheen does not allow heat or light back out. The glass is still transparent, yet is incredibly efficient at reducing energy loss.
