Different Types of Glass We Use for Our Windows

Top-quality windows must have top-quality components. This is why all our replacement windows feature only the best when it comes to glass panels. Take a look at the different glass options that you can choose to have in your new windows.

Different Types of Glass We Use for Our Windows



Our SmartSun glass panels provide excellent protection against ultraviolet rays without sacrificing the visibility of clear glass. SmartSun glass panels make great options for windows facing the outdoors or overlooking another wide area where you can’t afford to compromise the view. SmarSun panels can be improved with Heatlock® coating for even better performance.


PassiveSun glass panels are especially designed to help replacement windows absorb more heat from the sun. Because of this unique feature, PassiveSun  works best for homes in cool areas where every bit of extra warmth can help optimize your home’s heating.


Low-E4 glass panels are a jack-of-all-trades option, providing excellent thermal control for both cold and warm weather. If you’re not sure which option will work best for your home, our Low-E4 glass panels will make for a safe, energy-efficient choice. Low-E4 can also be improved with HeatLock coating.

Clear Dual-pane

Clear dual-pane windows are as simple as it gets, but the gap between the two individual panes make for a great insulative barrier, giving it superior performance over single-pane alternatives. Replacement windows with this option have the perfect balance of affordability and energy-efficiency.

"I would recommend RBA of Central Illinois for QUALITY windows and doors. Compared to our old cheap, thin vinyl windows, Andersen blows them away. You can easily tell by how well the sliding doors fit and close, and how heavy duty they are. We also cannot hear the wind rushing through the house in inclement weather anymore! And the black window frames we went with are amazing to look at. Aaron, Al, Darrell, and Cory all were professional and went all out to finish the job, given the weather they had to deal with. I would definitely recommend. They were also on top of communicating with me given the weather delays, and what I could expect for them coming out. Five stars!"
