When getting a window replacement, it’s important that you know what it’s made of. Since you’re replacing your old windows, make sure you pick something that’s better performing. If you’re not sure what to do or which window to select, ask your local expert, such as Renewal by Andersen® of Western NY.


Here, we help homeowners make the most of their window installation in Buffalo, NY. Here are three must-have features in a window replacement:

Energy Efficiency

A good window must have double-glazing with a combination of argon and krypton as gas filling. Two panes are always better than one. Nevertheless, optimizing the width of the air space between the two panes of glass is important for energy efficiency. If the panes are too far apart, it increases heat loss instead of reducing it. Argon gas blend is essential in improving the window’s insulation value. This gas combination also enhances the thermal performance of a window.


A strong window helps keep the structural integrity of a house. This is the reason Renewal by Andersen came up with Fibrex® frame material, which combines the stability and strength of wood with the maintenance ease of vinyl. With our exclusive Fibrex frame, you can be sure that your window will last long. Moreover, our heavy-duty windows are easy to clean and maintain. We can teach you the hassle-free way of cleaning them.

High Performance

Every homeowner deserves the best window. That is why Renewal by Andersen. We see to it that our windows are customized based on your needs and preferences. For maximum performance, we created three glass packages that provide different levels of energy efficiency. You can choose from our High-Performance™ Low-E4®, High-Performance Low-E4 SmartSun™, and High-Performance Low-E4® Sun glass packages.

These are three main features that you should look for in your windows. Be sure to consider the window style and design.
