Window glass or glazing is the most important part of every window. Getting the right kind of glass can dramatically improve indoor comfort and aesthetics as well as help you save on your utility bills. Our windows have special glass coatings that minimize the amount of heat that passes through the glass while maximizing the amount of visible light that is allowed inside.
In this post, Renewal by Andersen® of Houston discusses one of the key features of our home replacement windows: High Performance™ Low-E4® glass. Learn how this top-of-the-line glazing benefits your home.
- High-Performance Low-E4 glass: Homes in seasonal climates, where heating and cooling costs are a concern, can benefit from High-Performance Low-E4 glass. This option is 56% more energy-efficient in summer and 47% more energy-efficient in winter compared to standard dual-pane glass. This glass package can block up to 84% of harmful ultraviolet (UV) rays from entering your home. It also has excellent visible light transmission and a good solar heat gain coefficient (SHGC).
- High-Performance Low-E4 SmartSun™ glass: This glass option can block up to 95% of UV rays while greatly minimizing the amount of solar heat that enters your home. This is the perfect glass option for your window replacement if you want to protect your drapes, furniture and artwork from fading. It is unique among other glazing options because it offers the visible light transmittance of clear glass while providing thermal control similar to tinted glass.
- High-Performance Low-E4 Sun™ glass: This glass option is for homeowners who live in areas with hot, dry climates with little to no shade. It has our highest rating against solar heat gain, thanks to a subtle tint coating that reduces glare and excess light. High-Performance Low-E4 Sun Glass will help keep your home cool and comfortable in the summer because it reflects the majority of the solar heat away from your home.
- High-Performance Low-E4 SmartSun Glass with HeatLock™ Technology™: HeatLock Technology is Renewal by Andersen’s newest technology. It meets most of today’s strictest energy codes and requirements. The combination of Low-E4 glass and HeatLock Technology provides all the benefits of our SmartSun glass, but with the thermal control layer applied to the room-facing side. This technology helps lock in heat in the home during cold days.
