You often hear the phrase “windows pay for themselves” from replacement contractors. This promise of a significant return on investment has been a subject of dispute among experts. Today, we the record straight on how return on investment relates to replacement windows.
How Energy-Efficient Windows Work
To understand the connection between return on investment and replacement windows, let us first discuss an important aspect of replacement windows: energy efficiency. Most homes feature an energy envelope, that is, an insulated enclosure that consists of the attic, exterior walls and fenestrations (skylights, entry doors and windows). Proper insulation helps minimize heat transfer. It reduces heat gain in the summer and heat loss in the winter, resulting in reduced heating and cooling requirements, therefore, lower energy bills.
Windows are different from the other parts of the energy envelope because they’re mostly made of glass. This means conventional insulation, usually made of fiberglass or cellulose and used on siding and the attic, can’t be used. Energy-efficient replacement windows are instead equipped with double- or triple-pane glass. The sealed gap between interior and exterior surfaces dramatically reduce window conductivity. When set in insulated frames and installed properly, it helps reduce indoor heating and cooling requirements, resulting in energy savings.
This is where windows “pay for themselves”. The U.S. Energy Information Administration (EIA) estimates that as much as 48% of an average home’s energy consumption is spent on cooling and heating alone. Energy-efficient replacement windows offer many other desirable features, such as natural lighting and comfortable indoor spaces, but energy savings is the feature that lets you recoup a significant amount of your money.
It’s important to consider window service life and your annual energy consumption when figuring out your return on investment. A typical ENERGY STAR®-certified replacement window can cut your annual energy costs by up to 25%. If you have a fixed budget for your energy bills, the savings can add up over the lifespan of your windows. Investing in durable windows with good warranty coverage increases the likelihood of a better return on investment.
