Low-E Glass

Why Low-E Glass is Clearly Superior for Energy Efficiency.

Specialty Window

Donโ€™t let your energy escape! You can reduce energy loss and save money on heating and cooling with our exclusive High Performanceโ„ข Low-E4ยฎ glass. Hereโ€™s how.

Windows with plain glass panes canโ€™t stop energy from escaping from your home. The money you spend heating your home during the winter and cooling it all summer long is literally flying out your old windows! It takes the energy efficient properties of Renewal by Andersenโ€™s High Performance Low-E4 glass to stop the energy loss.

When it is cold outside, the warm air inside your home radiates through typical window glass, which also allows cold outside air to seep into the house. As a result your home heating system has to work overtime to make up the loss, costing you more money every time the thermostat ticks on.

The reverse happens during the summer, when hot, humid air infiltrates and cool, air-conditioned air radiates to the outside. So your air-conditioning system runs constantly.

The Solution is Low-E Glass.

Low-E is a specially coated glass that allows light to pass through, but controls the โ€œemissivityโ€ of heat energy. Emissivity is a measurement of how readily a material radiates absorbed energy. The lower the emissivity value, the more energy efficient the material. So a window equipped with Low-E glass helps to control the heat energy being allowed into and out of your home.

Thatโ€™s what makes Renewal by Andersenโ€™s High Performance Low-E4 glass and advanced High Performance Low-E4 SmartSunโ„ข glass such an important part of your new windowsโ€™ energy efficiency. With our High Performance Low-E4 or High Performance Low-E4 SmartSun glass installed, your windows become an effective barrier against thermal conductivity and energy loss.

Renewal by Andersenโ€™s exclusive High Performance Low-E4 glass offers these exceptional benefits:

  • 45% more energy efficient in summer as compared to ordinary dual panel glass*
  • 56% more energy efficient in winter as compared to ordinary dual panel glass*
  • High Performance Low-E4ยฎ SmartSun glass is 70% more energy efficient in summer and 45% more energy efficient in winter as compared to ordinary dual panel glass*

The High Performance Low-E4 glass in our Renewal by Andersen windows means youโ€™ll spend less money on heating and air conditioning to keep your home at a comfortable temperature. That results in lower utility bills all year โ€˜round.
