Cover Your Windows to Keep Cool in Extreme Heat

04/18/2023

Why does it matter?

Covering your home’s windows during extreme heat can help keep you and your house cooler and more comfortable when it matters most.

What do I need to know?

Covered windows:

• Reduce solar heat gain - Windows are one of the primary sources of solar heat gain in a home. When sunlight enters through the window, it can heat the interior and make your air conditioning work harder to keep your home cool. By covering your windows with blinds, shades, or curtains, you can reduce the amount of sunlight that enters your home, which can help keep the temperature down.

• Block UV rays - Ultraviolet (UV) rays from the sun can damage furniture, flooring, and other materials in your home. Covering your windows with UV-blocking shades or curtains can help protect your belongings from fading and other damage.

• Increase energy efficiency - When your air conditioning has to work harder to cool your home, it uses more energy and can increase your electricity bill. Covering your windows and reducing solar heat gain can improve your home's energy efficiency and lower your energy costs.

Overall, covering your windows during an extreme heat situation can help keep your home more comfortable and reduce your energy costs. It's important to choose window coverings designed for energy efficiency and UV protection and to keep them closed during the hottest parts of the day.

Where do I start?

There are several cost-effective ways to cover your windows during extreme heat to keep your home cool. Here are some of the best and least expensive options:

• Curtains: Curtains are another inexpensive option for covering your windows during extreme heat. They come in various materials and thicknesses, and when closed, they can block sunlight and reduce heat gain. It's best to choose curtains with light-colored, reflective fabrics to maximize their cooling effect.

• Reflective Blinds: Reflective blinds, such as aluminum or Mylar, are designed to reflect the sun's rays away from your home. They are an inexpensive option that can be easily installed and adjusted to control the amount of light and heat entering your home.

• Window Film: Window film is a thin, transparent sheet that can be applied to your windows to block heat and UV rays. It's an affordable option that can be easily installed, and it comes in various tints and designs to suit your needs.

• Window Shades: Window shades are available in different materials, such as bamboo, fabric, or vinyl. They can be mounted inside or outside the window frame and effectively block the sun's heat and glare. They also come in various designs and colors to match your decor.

Choose the window covering option that best suits your needs and budget while considering energy-saving benefits.
