There are a number of ways to scientifically measure the energy-efficiency of windows. Long Windows are one of the most energy-efficient windows you can purchase, by any of these measures.
A key factor of energy-efficiency is R value, which measures the thermal insulation capability of a window. The higher the R value, the better the window insulates to keep your home cool in the summer and warm in the winter.
Long Windows have industry-leading R values of 4.0 to 6.25. These are significantly higher than the R values for typical single- or double-pane windows - so advanced that they exceed Energy Star criteria for year 2015.
Another factor in energy-efficiency is the U-Factor, which measures how well the product traps heat inside your home. In this case, the lower the value the greater the energy-efficiency of your window.
Long Windows have an industry-leading U-Factor of 0.16. This surpasses the 2009 Energy Star Standards, which recognize a U-Factor of 0.35 as acceptable.
The guidelines for the Federal Tax Credit require that your windows carry a U-Factor of 0.30 or less. All Long Windows qualify; many Energy Star windows do not.
Yet another factor in energy-efficiency is the SHGC, which measures how well the window blocks solar heat coming inside the house. Again, the lower the value the greater the energy-efficiency of your window.
Long Windows have an industry-leading SHGC of 0.20. This surpasses the 2009 Energy Star Standards, which recognize a SHGC of 0.32 as acceptable.
The guidelines for the Federal Tax Credit require that your windows carry a SHGC of 0.30 or less. All Long Windows qualify; many Energy Star windows do not.
A final factor in energy-efficiency is the transmission of UV light. Long Windows utilize Heat MirrorTM Technology, recognized in Popular Science magazine as one of the top 100 inventions of the last 1,000 years.
Long Windows with Heat MirrorTM Technology only allow 0.3% of damaging UV rays into your home. Other windows on the market today allow roughly 50% of damaging UV rays into your home.
The difference is clear if you look at heat mapping photos of Long Windows versus competitors.
