Expert’s Choice: 10 The Best Window Coverings For Energy Efficiency in 2024

What type of window coverings are the most energy efficient?

There are several types of window coverings that are known for their energy efficiency. These include:

1. Cellular shades: Also known as honeycomb shades, these window coverings feature a unique design that creates a layer of insulation. The cells trap air, acting as a barrier between the window and the room, helping to regulate temperature and reduce energy loss.

2. Insulated curtains or drapes: These window coverings are typically made with multiple layers of fabric, including a thermal lining or interlining. This extra layer helps to block out drafts and maintain a comfortable indoor temperature.

3. Window films: These thin, adhesive films are applied directly to the glass surface of the window. They can reflect heat and UV rays while still allowing natural light to enter the room. Window films are particularly effective in reducing heat gain during the summer months.

4. Shutters: Interior shutters are solid window coverings that can provide insulation and control over light and airflow. They can be adjusted to allow natural light in while still providing privacy and energy efficiency.

5. Roller shades: These window coverings are made from a single piece of fabric that rolls up and down. They can be fitted with thermal backing to improve energy efficiency by reducing heat transfer.

What is the best material for energy-efficient windows?

The best material for energy-efficient windows is generally considered to be low-emissivity (low-e) glass. Low-e glass has a special coating that helps to reduce heat transfer through the window, keeping the interior of a building cooler in the summer and warmer in the winter. It also helps to block harmful UV rays, which can fade furniture and flooring. Additionally, double or triple glazing, which involves multiple layers of glass with a layer of insulating gas in between, further enhances the energy efficiency of windows by reducing heat loss.

How can I cover my windows to save energy?

To cover your windows and save energy, you can consider the following options:

1. Install window film: Window films, such as solar control films or low-emissivity films, can help reduce heat transfer and block harmful UV rays. They can also provide insulation during colder months.

2. Use thick curtains or blinds: Hanging heavy curtains or using insulating blinds can help keep heat inside during winter and block out sunlight during summer, reducing the need for heating or cooling.

3. Utilize cellular shades: Cellular shades, also known as honeycomb shades, offer excellent insulation properties. The air pockets within the shades trap heat, helping to maintain a comfortable indoor temperature.

4. Install window quilts or thermal curtains: These specially designed window coverings have added layers of insulation, creating a barrier between the window and the room. They can be particularly effective in older homes with drafty windows.

5. Consider window inserts: Window inserts are removable panels that fit snugly into the window frame, providing an additional layer of insulation. They are a more affordable option compared to replacing windows and can significantly reduce heat loss or gain.

6. Use window awnings or overhangs: Installing awnings or overhangs above your windows can help block direct sunlight, preventing excessive heat gain in the summer while allowing sunlight to enter during the winter months.
