How Long Do Replacement Windows Last?

 In Window Replacement

Learn how these 5 factors can impact the life of your windows.

If you need to replace your windows, you may be wondering how long they will last. The truth is that it depends on the brand of the window. For example, Renewal by Andersen® windows can last for many years to come thanks to the high-quality materials and features inherent in each style. Let’s take a closer look at five specific aspects of these replacement windows that can help lengthen their lifespan and allow you to get the most out of your investment.

1. Durability

Durability reigns supreme when it comes to a long window lifespan. Renewal by Andersen® replacement windows are comprised of an exclusive Fibrex® material, which is twice as strong as vinyl that many other brands use. Fibrex® can withstand the most extreme temperature swings and is known to maintain its stability and rigidity in every climate.

2. Energy Efficiency

If your replacement windows keep your home warm in the winter and cool in the summer, and save you money on your utility bills, they’ll last longer. Renewal by Andersen® windows feature incredible thermal insulating properties that can keep you comfortable in your home during any southern Wisconsin season. For windows that offer the most energy efficiency, ask your window us for SmartSun® glass. It is 70% more efficient in summer and 49% more efficient in winter as compared to ordinary dual pane glass. Consider pairing it with state-of-the-art HeatLock® Technology for near triple-pane performance in a double pane glass.

3. Beauty

If your windows are just as aesthetically pleasing to look at as they are to look through, they’ll be a long-term pillar of beauty in your home. Renewal by Andersen® features long-lasting color choices to ensure your new windows will complement the interior and exterior design of your home. And their exclusive Fibrex® material is strong enough that it doesn’t need the bulk of a traditional vinyl window. With a narrower frame, you’ll have a larger, more beautiful reveal of the outdoors.

4. Installation Technique

Another aspect that greatly affects how long your replacement windows will last is the way they are installed. Are the installers certified? Do they thoroughly inspect the glass, casing, trim, seal, and hardware to ensure everything fits and functions properly, and is free from dust, dirt, or cracks? Renewal by Andersen® replacement windows are installed by Certified Master Installers who have experience working in a wide variety of homes and will go the extra mile to ensure you are completely satisfied.

5. Warranties

To help ensure your new replacement windows will stand the test of time, look into the warranties of each brand you’re considering. Renewal by Andersen® recently tested the windows that were professionally installed in a home 20 years ago in a harsh Minnesota climate. They found that the windows look and operate just as as they did on installation day two decades ago. Based on this experiment, Renewal by Andersen® so confident your new windows will last that they offer a few fully transferable warranties to help guarantee a long life. A 20-year warranty is for glass and Fibrex® material, a 10-year warranty covers locks, hinges, and other components, and a 2-year warranty covers professional installation.
