How Window Shutters Give You Control Over Room Temperature When closed, shutters become the next best barrier against Philadelphia’s wind and variable temperatures – after your windows. Other window treatments such as shades, blinds, and draperies block most of the temperature from outside, but not all. And, when you need a sturdy window treatment that gives you a comfortable seat by the window, Polywood® shutters are the preferred product. We make Polywood shutters 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 up to 30 degrees of airflow and lessens heat transfer by 45.96%. This translates into energy savings for your home – and complete room temperature control. Your home’s HVAC system will work faster now that you’ve reduced most of the impact from the weather outside. When you want to feel some of the effects of the external elements, simply move the louvers open and adjust them to how you’d like them. You can get more window treatment temperature control. Simply follow the instructions below to close your shutters properly. How to Close Your Shutters for Optimal Temperature Control There are two parts of your shutters that should be closed to seal off outdoor 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, check 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. The best way to do that is to run your hand up the tilt rod, pushing in as you go. This is also true for taller shutters. Sometimes a little push at the bottom of the tilt rod isn't enough and can leave gaps at the top.
