The Benefits of Renewal by Andersen® Glass Packages

The Renewal by Andersen® window replacement process focuses on ensuring the long-lasting beauty and energy efficiency of your new windows through innovative product technology and cutting-edge installation methods. A big part of what makes our windows perform so well is the high-performance glass packages they’re built with.

High-Performance™ Low-E4® Glass

This is our standard glass package. Compared to ordinary dual pane glass, it is 45% more energy-efficient in winter and 56% more efficient in summer. This option is perfect for homeowners living in areas with seasonal climates such as Washington State.

High-Performance™ Low-E4 SmartSun™ Glass

The most energy-efficient glass option offered by the company, it effectively blocks the sun’s heat and up to 95% of accompanying UV rays without compromising the amount of natural light admitted into your home.

High-Performance Low-E4 SmartSun Glass With HeatLock® Technology™

This SmartSun glass utilizes a HeatLock Technology coating that reflects escaping radiant heat back into the room. This helps in maintaining indoor warmth during the cooler months.

High-Performance Low-E4 Sun Glass

This glass package works well for homes situated in areas with hot, dry climates. Heat from the sun is filtered through a subtle tint coating, minimizing solar heat gain while reducing entry of visible light.

Along with these glass packages, our Fibrex® frame material helps to further enhance the energy efficiency of our windows. This frame material combines the durability of wood with the low-maintenance nature of vinyl. The result is a high-performance, energy-efficient window that will last for many years with minimal maintenance.

"Thanks Tyler, Carlos, Chris & John for a GREAT and PROFESSIONAL job. Not only are the new windows and balcony slider great looking, but they are keeping us cooler (summer) and we are sure they will keep us warmer in the winter. We are very happy with our new windows. The “Anderson Gang” did a super job, from beginning to end. Other then being a “little late”, all went well. Your crew ROCKS .. thank you very much .. Dagmar and Glen Fisher"
