Our Low-E4® Glass Options: An Overview

Getting the right kind of glazing or window glass is a huge factor when it comes to replacement window installation. Purchasing not only is ideal but what contributes to your property’s energy efficiency is highly critical. At Renewal by Andersen®, you’ll be offered a variety of options that are tailored to your needs. Here are our glass options you can choose from:

Windows
  • High-Performance™ Low-E4® Glass. Houses in seasonal climates, where heating and cooling costs are trouble, can benefit from this option. It 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 UV rays from entering your home and has a good solar heat gain coefficient.
  • High-Performance Low-E4 SmartSun™ Glass. This is equipped to block up to 95% of UV rays, while greatly minimizing the amount of solar heat that enters your property. This is the best glass option for your window replacement if you want to protect your drapes, furniture, and artwork from fading. 
  • High-Performance Low-E4 Sun™ Glass: Any double-hung window repair expert would suggest this is for homeowners who live in areas with hot, dry climates with little to no shade. It has the highest rating against solar heat gain with the help of its subtle tint coating that reduces glare and excess light. 
  • High-Performance Low-E4 SmartSun Glass with HeatLock™ Technology. HeatLock Technology is Renewal by Andersen’s latest innovation that 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.
