Renewal by Andersen® of Austin offers different window glass options to help you achieve your energy-efficiency goals. Our Low-E4® glass is our standard offering, which is ideal for climates where heating and cooling are both a concern. Our Low-E4 SmartSun™ glass works wonders for warm climates, with an optional HeatLock™ coating that delivers triple-pane performance from double-pane units. Our Low-E4 Sun® glass sports a subtle tint to reflect as much solar heat as possible.
Choosing the right glass package for each of your windows and patio doors can be easy. Here’s what you need to remember:
Assess Your Needs
Think about how you intend to reach your desired level of comfort, and determine how you can use windows to achieve it. Do you depend a lot on your air conditioner or you are a fan of optimizing ventilation to expel indoor moisture and release heat? How much does sun damage bother you?
Answering these questions can help you narrow your options. Considering that your rooms have unique energy efficiency requirements, you shouldn’t hesitate to outfit your double-hung, picture, sliding and casement windows with different glass options.
Check ENERGY STAR® and NFRC Labels
Energy-efficient fenestration products are not all equal. Those deemed excellent in Alaska wouldn’t necessarily deliver positive results in the Lone Star State.
The ENERGY STAR seal determines which units meet the energy-efficiency requirements in the Southern Climate Zone where Hays, Travis and Williamson counties are located. To learn about each window’s specific qualities, read the NFRC (National Fenestration Rating Council) label. It shows the energy performance ratings of the product, shedding light on its ability to insulate, block solar heat, allow sunshine and resist air leakage.
Consider Patterned Glass
If you want to boost a room’s thermal properties and catch as much daylight as possible without giving up privacy, choose translucent glass. Our bay, bow and custom windows come in different patterns to protect your privacy without sacrificing sunlight.
Increased daylighting helps cut down your energy consumption and cooling expenses by reducing your dependence on artificial lighting. Electric lights cost money to power and also raise your indoor temperature. According to the Department of Energy, traditional bulbs only use 10% of energy for light and waste the rest as heat.
