You know the need for well-insulated attics and walls, but did you know that window coverings can be an easy step to reduce your energy bills? Here are just some of the ways that energy-efficient window coverings like our Polywood® plantation shutters can stop the Phoenix summer heat and keep your air conditioning in. 
  1. Seals off airflow - Treatments that fit tight in your window opening seal off air and can lessen the hot airflow from outside to inside. Our Polywood plantation shutters block as much as 30 degrees of heat flowing through your windows when they’re fully closed. 

  2. Reduces heat transfer - As the sun comes through your window it warms up the glass and that heat might then flow to the inside space. Energy efficient treatments reduce this heat transfer. Polywood shutters can slash heat transfer by almost 46% and will be 70% more energy efficient than hardwood shutters and are 1600% more energy efficient than aluminum blinds.

  3. Maximizes R-value - R-value quantifies the energy efficiency of insulating materials. It’s used for windows, insulation, and window treatments. To be designated as energy efficient window coverings, they should use a high R-value. When Polywood shutters are completely closed and paired with a double-pane window, their R-value is 6, which is fairly high for window treatments.

Now that you know a few ways that window treatments promote energy efficiency, what specific features should you look for?
 

Window treatments that can encase the window or trap air

The most efficient way to stop airflow is by confining the air between the window and your room. You can accomplish this with window treatments like Polywood shutters that completely encases the window when closed. What’s exciting about our shutters is that Polywood shutters even employs weather stripping which thoroughly blocks off any air transfer. The video below explains how to best use Polywood shutters to fully experience the power of energy efficiency. (Hint: When your Polywood shutters are open, they let heat through and are reducing their energy efficiency).


An alternative window treatment option is cellular shades.  They trap air in honeycomb-shaped cells. However, if there’s a gap between the window and the shades, you can still have airflow creeping from under the shades.

Light colors reflect the sun and are a good choice for energy efficient window coverings. It’s why our Polywood shutters are available in three shades of white and also have a UV-reflecting layer to help your AC bills stay low.

If you want curtains or drapes, look for a light-colored material that reflects the light.
