WHAT MAKES A WINDOW ENERGY-EFFICIENT? – PART 2: WINDOW STYLES & ENERGY EFFICIENCY

It’s not just the materials that make a window provide better energy efficiency, what with different styles offering their own way of keeping a home ventilated, insulated and illuminated. Knowing what each style has to offer can help you decide which one to get to achieve your energy-efficiency goals.

Double-Hung Windows

Double-hung windows provide great ventilation control as both sashes are operable, allowing homeowners to use just one or both depending on their needs. They also let in moderate amounts of natural light, contributing to daylighting needs.

Casement Windows

Because casement windows can be opened all the way, they create the best opportunities for ventilation. Their large openings let a lot of air in and out and the sash can be angled in such a way that it captures breezes effectively.

Sliding Windows

Sliding windows can only open as wide as one sash. However, sliding window sashes are generally bigger than the ones double-hung windows use so the former is able to offer better ventilation. Glass areas are also usually unobstructed by muntins, letting in a lot of light into a room to aid in illumination during the day.

Bow & Bay Windows

Bow and bay windows are both made up of a series of smaller windows configured together, creating large areas of glass that let homeowners take advantage of natural light. All those windows also mean more openings, allowing bow and bay windows to provide excellent ventilation and expansive views.

Picture Windows

Picture windows are also known as fixed windows because they can’t be opened. This means they can’t offer ventilation because they are sealed, but picture windows are the best option for optimal insulation. Picture windows also have some of the largest glass areas around, making them great daylighting tools.

We’ll be wrapping up this three-part blog series by talking about how window features contribute to achieving energy efficiency in a home, complementing style and material options.

Reviews

"We had a large picture window and two side windows replaced. Everyone from the person who took our order to the installers were top notch. We got exactly what we wanted. Granted, we had to wait a few months, just like you do for everything these days, but we were told that up front. The windows were well worth the wait. We've replaced windows before by going to home maintenance stores. Don't waste your money on those. Our Renewal by Andersen windows look great, they operate like a dream, and are worth every penny. Quality through and through."
