How Window Shutters Give You Control Over Room Temperature When closed, shutters become the next best barrier against Southern California’s wind and variable temperatures – after your windows. Other window treatments such as blinds, shades, and draperies block most of the temperature from the outdoors, but not all. And, when you need a sturdy window treatment that gives you a cozy seat by the window, Polywood® shutters are your best product. Polywood shutters are built from a synthetic polymer. Polywood shutters insulate up to 70% better than an equivalent traditional wood shutter. In fact, the Polywood Shutter Insulating System blocks as much as 30 degrees of airflow and lessens heat transfer by 45.96%. This translates into energy savings for you – and total control over room temperature. The heating and cooling system in your house won’t have to work so hard now that you’ve reduced most of the impact from the weather outside. When you want to let in some of the light and be more exposed to the outside temperature, just slant the louvers and adjust them to how you’d like them. You can get even more window treatment temperature control by closing your shutters properly. How to Close Your Shutters for Maximum Temperature Control Two parts of your shutters ought to be closed to seal off outside temperature: the panels and the louvers. To close your Polywood shutter panels properly, swing them toward the window. As you move the panels into the shutter frame, ensure that the pieces of weatherstripping interlock along the vertical ends of your shutters. To close your louvers properly, push the tilt rod toward the louvers, making sure the top of the tilt rod fits into the "mouse hole," which is above the top louver. It is best to run your hand up the tilt rod, pushing in as you go. This is particularly true for taller shutters: sometimes a little push at the bottom of the tilt rod isn't enough and doesn’t close gaps at the top.
