How Window Coverings makes an Energy Efficient House


It may be common knowledge that insulating the walls and attic of a home helps to keep it more energy efficient—allowing less heat and air-conditioned air to escape the home and therefore reducing utility bills. But it may come as a surprise that window coverings can also serve as a way of insulating a home.

Shades, draperies, blinds and other window treatments each have insulation factors to consider. In fact, updating window treatments can be a simple step in keeping the heat inside in the winter and outside in the summer—preventing energy from literally going out the window.

Here are the insulation factors to consider in the search for energy-saving window coverings:

The R-value of window treatments

When it comes to insulation, R-value is key. This measurement defines a window treatment’s ability to resist heat travelling through it. Therefore, window coverings with a higher R-value will help insulate a home better than those with a lower R-value.

On average, a window has an R-value of 0.9 to 3.0. Window coverings with a higher R-value help seal air gaps and create an effective barrier between a window and a room. This can mean an annual savings in energy use (and costs) of 10 to 25 percent.

The installation process

Believe it or not, the installation process may impact the R-value of window coverings. To maximise heating and cooling savings, homeowners should do their homework before beginning the work. Ensuring that window coverings fit perfectly will help maximise insulation, therefore reducing the energy it takes to heat or cool a home.

The amount of air space between the glass layers of a window

Window coverings can help limit heat loss in winter and heat gain in summer. However, it also is important to note that the amount of space between the glass layers of a window may impact air leakage and infiltration in a home.

Using caulk and weather stripping around windows is a great way to limit air leakage, and they can be used in conjunction with window coverings to help further increase energy savings.

Lastly, homeowners can always layer window coverings on top of one another to increase insulation. This will reduce energy lost through a home’s windows and ensure these windows can make a bold, beautiful statement as well.

A window covering is more than just a fashion statement—it affects the comfort of a home as well as monthly utility costs. Examine the window treatment options that are available, and discover versatile window coverings that can provide a form as well as function.
