What Makes Our Replacement Windows a Cut Above the Rest?

With so many replacement window options and window contractors to choose from, selecting the right products and the right installation team can be challenging. When you turn to Renewal by Andersen®, however, you can enjoy the best of both worlds: long-lasting, durable, incredibly energy-efficient replacement windows and highly skilled installers. Today, we discuss the features that make our replacement windows a cut above the rest.

High-Performance™ Low-E4® Glass

Glazing is the most important part of every window. The right kind of glass admits abundant natural light while blocking the unwanted components of sunlight, such as heat gain and harmful UV rays. Glass is a naturally conductive material, so achieving all these features is a challenge for any window manufacturer.

All Renewal by Andersen, all our window replacement units are equipped with High-Performance™ Low-E4® glass. A dual-panel assembly separated by an insulated spacer eliminates contact between interior and exterior surfaces. This significantly reduces heat transfer, helping minimize heat loss on cold days and heat gain on hot days. This takes the burden off your HVAC system, allowing you to save money on energy consumption. In addition, the low emissivity (Low E) coatings on our high-performance glass block unwanted UV rays and heat from the sun, while an exterior metal oxide coating reduces water spotting by up to 99% when activated by sunlight.

Fibrex® Frames

Your replacement windows should have high-quality frames that are strong enough to allow slim profiles without compromising strength. The material should also be durable enough to resist warping and cracking from extreme temperature changes for many years. And, of course, you want a frame material that comes in a wide range of colors and finishes so you can achieve exactly the look you want.

Our replacement windows are built with our exclusive Fibrex frame material, a composite made from wood fibers and polymers. Fibrex combines the strength of wood and the low-maintenance nature of vinyl. Fibrex is guaranteed to remain vibrant, require no repainting and not chip, crack or peel during the window’s lifespan. Fibrex complements the insulative properties of our High-Performance Low-E4 glass, resulting in windows that deliver exceptional energy efficiency and longevity.

Custom Windows

We offer a wide selection of replacement window styles, from the classic double-hung and bay windows to specialty window shapes and window walls. Our replacement windows are all built to size, which means not only can we build any window configuration you can think of, but we can also build it to fit your existing window opening—perfect for those working on restoration projects.
