Low-E4® Glass Options: A Glass Package for Your Every Need

Renewal by Andersen® of Austin offers long-lasting windows with energy-efficient glass. Our High-Performance™ Low-E4® glass package helps stabilize your indoor temperature no matter the weather outside.

Read on as we discuss our specialized glass packages that give you that added layer of protection only Renewal by Andersen of Austin can provide.

High-Performance™ Low-E4®

Our standard Low-E4 glass package features a double-glazing design that deflects infrared rays from the sun, keeping your interior from getting too hot. This glass package is 56% more energy-efficient in summer and 47 percent more energy-efficient in winter compared to regular dual-pane glass. All our windows, including our casement windows, come standard with this basic glass package.

High-Performance™ Low-E4® SmartSun™ 

For better UV protection, you can upgrade to our Low-E4 SmartSun glass, which is 70% more energy-efficient in summer and 49% more energy-efficient in winter than ordinary dual-pane glass and blocks 95% of ultraviolet radiation. It admits the same amount of visible sunlight as clear glass but its thermal control is similar to that of tinted glass. It also muffles exterior noise for a cozy and peaceful interior.

Plus, we offer our SmartSun glass package with an optional HeatLock™ technology. This allows the window to “trap” the heat in the room instead of letting it dissipate through the glass outside. This affords you a level of insulation reminiscent of triple-pane glass.

High-Performance™ Low-E4® Sun™

Protect yourself from the harsh Texas heat with our Low-E4 Sun glass package. To combat the intense heat, we installed a subtle layer of tint to further deflect heat from entering your home. Of all our glass packages, this is the one with the most resistance to solar heat gain.
