The Top 3 Factors That Affect Window Performance

Window Performance

One of the best ways to save money is to improve your home’s energy efficiency. This includes choosing the right windows for your needs. While there are several products today that can drive your comfort levels up and your utility bills down, not all of them are created equal.

Window Performance

To make the most of the energy-saving benefits of your windows, it pays to learn what affects their performance. Renewal by Andersen® of Long Island, your window replacement expert, explains further:

Frame Material

Frames do more than just keep your windows sturdy and beautiful. Depending on their material, they also contribute to your home’s insulation. To make sure that your units remain airtight throughout the years, choose framing materials that don’t expand and contract too much with fluctuating temperatures.

For long-term efficiency, we only use Fibrex® composite frames for our windows. It boasts the durability and insulating properties of wood, as well as the easy upkeep of vinyl. As Fibrex products don’t warp, corrode and rot, they won’t easily allow air leakage.


To minimize heat gain that can cause discomfort, most windows today come with low-emissivity (Low-E) glass. This keeps your home cooler during summer and warmer during winter. In turn, you reduce your energy costs. For optimum efficiency, we equip our units with High-Performance™ Low-E4® glass. Not only does this help stabilize your indoor temperature, it also protects you from harmful UV rays.


Even high-end windows won’t perform at their best after a subpar installation. In fact, this causes them to sustain more problems, which can shorten their service life. This is why you need to work with trusted window contractors like Renewal by Andersen of Long Island. We are experienced working in all kinds of homes, and you can expect only the best from us.
