The Right Window Treatments For Summer Heat in Southern California

Kimball Jones

When it’s hot and sticky outside, keeping cool is critical. A great way way you can reduce your energy bills and feel cool is to use energy efficient window treatments for summer in Southern California. 

While not all window treatments have the same benefits, we’ll describe exactly how window treatments can block heat from seeping in. Also, we’ll let you in on how to find the most energy-efficient window coverings so you can keep hot air where it should be - outside.

Here’s How Energy Efficient Window Treatments Block Heat

You know the benefits of well-insulated attics and walls, but did you know that window coverings can be a great option to reduce your energy bills? Here are just some of the ways that energy-efficient window treatments like our Polywood® shutters can block the Southern California summer heat and keep your house cool. 
  1. Obstructs airflow - Treatments that completely covers your window opening seal off air and could reduce the warm airflow from outside to inside. Our Polywood shutters stop as much as 30 degrees of heat flowing through your windows when they’re shut completely. 

  2. Reduces heat transfer - When the sun shines through your window it heats up the pane and that heat might then flow to your room. Energy efficient window coverings hinder this heat transfer. Polywood shutters lessen heat transfer by almost 46% and will be 70% more energy efficient than hardwood shutters and about 1600% more energy efficient than aluminum blinds.

  3. Uses a high R-value - R-value quantifies the energy efficiency of insulating materials. It’s used for windows, insulation, and window treatments. You want a window treatment to earn a high R-value. When Polywood shutters are closed and used with a double-pane window, their R-value is 6, one of the highest values for window treatments.

Now that you understand some of the ways that window treatments stop heat transfer, what exactly should you want to see in a treatment?
 

Window treatments that are designed to completely cover the window or trap air

The most efficient way to stop airflow is by sealing off the window from your AC. You can accomplish this with window coverings like Polywood shutters which completely covers the window when closed. What sets us apart from other plantation shutters is that Polywood shutters even have weather stripping that thoroughly blocks off any air transfer. The video below shows how to best use Polywood shutters to fully experience the power of energy efficiency. (Hint: When your louvers are open, they let heat through and are reducing their energy efficiency).


Another window covering option is cellular shades.  They trap air in honeycomb-shaped little pockets. However, if there’s a gap between the window and the shades, you can still have airflow entering from under the shades.

Light colors reflect heat and make a good choice for energy efficient window treatments. Our Polywood shutters are available in three hues of white and utilize a UV-reflecting layer to help your home stay cool.

If you’re buying curtains or drapes, pick ones with a light-colored backing that reflects the light.
