The Best Window Treatments For Summer Heat in Honolulu

Darren Wong

When it’s warm outside, keeping cool is critical. A way you can decrease your energy bills and stay cool is to use energy efficient window treatments for summer in Honolulu. 

As not all window treatments are made the same, we’ll describe precisely how window treatments can block heat from coming in. Also, we’ll show you how to figure out the most energy-efficient window treatments so you can keep summer heat outside and the cool air inside.

How Energy Efficient Window Treatments Stop Heat

You understand the importance of well-insulated attics and walls, but did you know that window treatments can act as an easy step to prevent skyrocketing energy bills? Let’s list a few ways that energy-efficient window treatments like our Polywood® shutters can thwart the Honolulu summer heat and keep your home comfortable. 
  1. Seals off airflow - Treatments that completely covers your window opening trap air and could reduce the warm airflow through your windows. Our Polywood plantation shutters stop as much as 30 degrees of heat coming from your window when they’re fully closed. 

  2. Cuts down on heat transfer - As the sun comes through your window it warms up the glass and that heat will then transfer to inside rooms. Energy efficient window coverings weaken this heat transfer. Polywood shutters reduce heat transfer by almost 46% and have shown to 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 a material. It’s used for windows, insulation, and window treatments. You should seek out high R-value window coverings. When Polywood shutters are completely closed and used with a double-pane window, their R-value equals 6, one of the highest values for window treatments.

Now that you know some of the ways that window treatments stop heat transfer, what functions should you look for?
 

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

The best way to halt airflow is by covering every place air can come through the window. You can do this with treatments like Polywood shutters that completely covers the window when closed. And unlike other plantation shutters, Polywood shutters even have weather stripping which further stops air transfer. The video below shows how to correctly close Polywood shutters to optimize their energy efficiency. (Hint: When your Polywood shutters are open, they will allow heat through and are diminishing their energy efficiency).


An additional window treatment option is cellular shades.  They trap air in honeycomb-shaped material. However, when you have the possibility of a gap between the window and the shades, you can find airflow creeping from under the shades.

Light colors reflect the sun and make a great choice for energy efficient window treatments. Our Polywood shutters come in three variations of white and use a UV-reflecting coating to help your energy bills.

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