Energy Efficient Windows

Aiming for energy efficiency is one of the easiest ways to tackle climate change while also working to directly reduce energy costs across the board. As such, installing energy-efficient replacement windows is one of the best ways you can save money on your home’s energy bills while also doing your part to help protect the environment.

What is Energy Efficiency?

According to, energy efficiency is “the use of less energy to perform the same task or produce the same result.” In terms of energy-efficient homes, this means using less energy in order to heat or cool your home. As you might expect, windows (along with entry doors) are a key factor in the overall energy efficiency of your home.

Why Energy-Efficient Windows Save You Money

Energy-efficient windows are an essential upgrade that can substantially cut your home’s heating and cooling costs. In data provided by the Department of Energy, it’s revealed that a significant 25%-30% of residential heating and cooling energy use is due to heat gain and heat loss through windows. Hence, investing in energy-efficient replacement windows can lead to notable savings by reducing your energy consumption throughout the year.

These windows are designed with advanced technologies to provide superior insulation, keeping your home warm in winter and cool in summer without overworking your heating and cooling systems. They incorporate features like low-emissivity (Low-E) coatings, double or triple glazing, and other efficient measures.

Not only do you save money, but you also contribute to a sustainable environment by reducing your home’s carbon footprint.

Why Our Windows Are Better

The National Fenestration Rating Council (NFRC) tracks and rates the energy performance of windows for consumers. Two of these values are “U-factor” and “air infiltration.”

A “U-Factor” is the rate at which a window transmits non-solar heat flow, and “Air infiltration” is the amount of air leakage through a frame in a given time. The lower the U-factor, the more energy-efficient the window, and the lower the air infiltration rate, the more airtight that window will be.

As for insulation, our windows are infused with argon gas and actually assembled in a dedicated argon chamber. They also use a wide, stainless steel spacer which, unlike the aluminum components of our competitors, does not conduct the cold, meaning you’re kept nice and toasty in the Winter.

An R-value shows how proficient a given form of insulation is at keeping heat from leaving (or entering) a home. The higher the R-value, the more effective and energy efficient the insulation. A typical home has an R–value of 13; our windows have an R-value of 21, meaning they have even more insulative power than an average house!

Put simply, our windows perform better, last longer, are more energy efficient, and have a lifetime warranty. None of our competitors, such as Marvin, Pella, and Renewal by Andersen, measure up to the rigorous energy-efficient standards held by Home Guard.

Maximizing Energy Efficiency with Proper Installation and Maintenance

Even the best energy-efficient windows can underperform if not installed correctly or maintained over time. Do not underestimate the importance of professional installation and regular maintenance to maximize your return on investment with energy-efficient windows.

The Importance of Professional Installation

Incorrect installation can lead to gaps, air leaks, and improper insulation, negating the energy-saving benefits of your energy-efficient windows. It’s essential to rely on experienced professionals to ensure your windows are installed correctly, providing the energy efficiency and performance you expect.
