Energy efficiency is one of the most crucial factors that you must consider when choosing a window style. However, since there are different window styles in the market today, it is not surprising that all window styles don’t provide the same level of energy efficiency. This leads us to inquire about the most energy-efficient style of window.

Picture windows are the most energy-efficient

Without mincing words, picture windows are the most energy-efficient windows you can get. They are stationary and fixed into the frame. Since you cannot open or close them, they are the most airtight windows. They don’t enable conditioned air to leave a room or drafts to come inside it.

Picture windows are also great for rooms where you need lots of natural light due to their narrow frames. In addition, they provide you with a great view of the outdoors.

Despite being the most energy-efficient style, they may not be good for your building if you need natural ventilation. To deal with this issue, you should only go for premium picture windows with Low-E glass. Alternatively, the window style can be combined with operating units that allow natural air to come into the house.

Casement windows are the second most energy-efficient

Casement windows are known to be more energy efficient than other windows styles that can be opened and closed. In terms of overall energy efficiency, they are only second to picture windows.

The design of casement windows is the main factor that makes them more energy efficient than most other options. Basically, they come with a strong seal on each of their four sides. Once they are closed, the frame will be pressed tightly by the sash. Resultantly, it will be difficult for any amount of air to pass through the window.

Unfortunately, most other window styles don’t have this kind of design. They don’t seal properly; hence, you can expect air leaks between their frame and sash.

Other energy-efficient windows

While picture and casement window styles are the most energy-efficient options, you should note that there are a few other choices. Bay and bow windows, for instance, are energy-efficient, especially when casement windows are added to their design. These windows are often big with lots of openings; hence, they tend to be more energy-efficient than other options.

Double-hung and sliding windows are also energy efficient. This is because there have been significant improvements in their design. Nowadays, they have low air leakage; so, you don’t have to worry about losing air from your home when using double-hung windows or sliding windows.

However, energy efficiency is not the only factor for determining the best windows and doors for your home. So, if you are still confused about the window styles you choose for your building, it is recommended that you talk to a window and door professional. This professional will assess your home and help you to decide the best windows and doors that can suit your needs and preferences.
