The Basics of the Energy Efficiency Rating

No matter what type of window, from casement windows to double-hung windows, there are three factors that determine how energy efficient the window is. First, there are non-solar heat losses and gains through the window, including conduction, convection, and radiation. Secondly, solar heat gains occur as the sun beats down on the glass of your window.

Finally, there is basic airflow. This might be intentional, such as opening up a window for a breeze to blow through. Unintentional airflow can result from improper installation, loose or damaged seals, and design flaws.

The energy efficiency rating gives you a clear picture of what to expect from your casement windows. Insulating values can tell you how well the casement windows hold in heat, how well they protect against the harmful rays of the sun, and how easy it is for air to move through your window.

Casement Windows Energy Efficiency

Enter casement windows and their energy efficiency rating. The crank style of a casement window means the seal must be tight when closed, effectively preventing airflow. Double-pane or triple-pane casement windows can insulate more effectively than single-pane windows. Choosing Low-E or other treated glass can significantly improve your casement windows energy efficiency as well.

Professional installation of your casement windows can help ensure that your energy efficiency goals are met. When it comes to keeping tight seals, preventing unwanted airflow, and keeping solar gains down, your beautiful new casement windows are only as good as their installation.
