How Window Coverings Improve Energy Efficiency


Improving the energy efficiency of homes and businesses is something many people consider. This includes insulation, energy efficient light bulbs, and high-efficiency appliances. However, there’s another factor that often goes overlooked: window coverings. Choosing the right window coverings for your space can improve your energy efficiency and reduce your energy bills.

Energy Efficiency Window Coverings

A building’s ability to keep heat inside during the winter and cool air inside during the summer primarily determines the space’s energy efficiency. Windows are a key factor in this equation, as they are a major source of heat transfer between the inside and outside of a building. In fact, according to the U.S. Department of Energy, windows account for up to 30% of a building’s heating and cooling energy loss.

This is where window coverings come in. By adding an extra layer of insulation to your windows, window coverings reduce the heat that escapes during the winter and the heat that enters during the summer. This reduces the energy needed to heat or cool your space, leading to lower energy bills and a more comfortable indoor environment.

Types of Window Coverings for Greater Energy Efficiency

Several types of window coverings can improve the energy efficiency of your space. Let’s take a look at some of the most popular options:

Cellular Shades: Also known as honeycomb shades, cellular shades are made of two or more layers of pleated fabric that form a honeycomb shape. This design creates pockets of air that act as a barrier against heat transfer, making cellular shades one of the most energy-efficient window coverings on the market. They are also available in a wide range of colors and styles to match any décor.

Window Film: Window film is a thin, transparent sheet applied directly to your window’s surface. It is designed to reflect heat and block UV rays, reducing the heat entering your space. Window film is a good option for those who want to maintain the view outside their windows, as it doesn’t obstruct it.

Insulated Curtains: Insulated curtains are made of heavy fabrics, such as velvet or wool, and feature an additional layer of insulation in between the front and back layers. This extra layer helps to reduce heat transfer, keeping your space warmer in the winter and cooler in the summer. Insulated curtains are also available in various styles and colors to match your décor.

Roller Shades: Roller shades are made of a single piece of fabric that is rolled up and down to cover your window. They are available in a variety of materials, including light-filtering and blackout fabrics. While not as energy-efficient as other options, roller shades can still help reduce heat transfer and are a good choice for those on a budget.

Choosing the Right Window Coverings for Your Space

When choosing window coverings for your space, it’s essential to consider factors like the climate you live in, the orientation of your windows, and the amount of sunlight they receive. For example, if you live in a cold climate, choose cellular shades or insulated curtains to keep your space warm in the winter. If you live in a hot climate, select window film or roller shades to block out the sun’s heat.

Choosing window coverings that fit your décor and lifestyle is also important. Window film is an excellent choice to maintain your view outside. If you want to add a touch of elegance to your space
