Renewal by Andersen replacement windows are known for their beauty and durability. They’re also known for their high-performance Low-E4 glass. How does Low-E4 glass compare to regular dual-pane glass? Low-E4 glass is layered with 11 microscopic coatings that cut UV transmissions down to 17% with virtually no effect on the clarity or color of the light that enters your home. Regular dual-pane glass lets 63% of UV light into your home.
Andersen’s Low-E4 glass uses a hermetically-sealed system for optimum insulation from heat, cold and sound. When the windows are constructed, a low-conductivity spacer is used to separate the two panes of glass. The space between the two panes is then filled with an argon gas blend. This gas blend helps minimize thermal transfer.
Andersen’s Low-E4 glass is 56% more energy-efficient in the summertime and 45% more efficient in the winter compared to regular dual-pane glass. Andersen’s Low-E4 SmartSun glass is even better. It is up to 70% more energy efficient in the summer and 45% more energy efficient in the winter than regular dual pane glass. This glass also blocks 95% of harmful UV rays.
