How Window Shutters Give You Control Over Room Temperature Closed shutters are the next best defence against the extreme temperature and wind in Tampa, coming right after windows. Other window treatments such as shades, blinds, and draperies block most of the temperature from the outdoors, not all. And, when you need a sturdy window treatment that gives you a comfortable spot by the window, Polywood® shutters are your best choice. We build Polywood shutters from a synthetic polymer that insulates up to 70% better than a comparable traditional wood shutter. In fact, the Polywood Shutter Insulating System blocks up to 30 degrees of airflow and reduces heat transfer by 45.96%. This translates into energy savings for your wallet – and complete room temperature control. Your home’s heating and cooling system won’t have to work so hard now that you have reduced the impact from the outside weather. When you want to bring in some of the effects of the external elements, simply tilt the louvers open and adjust them to a preferred position. You can get even more window treatment temperature control. All you have to do is close your shutters properly. How to Close Your Shutters for Complete Temperature Control Two parts of your shutters ought to be closed to seal off outdoor temperature: the louvers and the panels. 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. The best way to do that is to run your hand up the tilt rod, pushing in as you go. This is especially 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.
