How Window Shutters Help You Control Room Temperature Closed shutters are the next best barrier against the extreme temperature and wind in St. George, coming right after windows. Window treatments such as blinds, draperies, and shades block most of the external temperature, not all. And, where a sturdy window treatment means the difference between a pleasant seat by the window and one that’s not, Polywood® shutters are the optimal product. We build Polywood shutters from a synthetic polymer that insulates up to 70% better than an equivalent traditional wood shutter. As a matter of fact, the Polywood Shutter Insulating System blocks as much as 30 degrees of airflow and diminishes heat transfer by 45.96%. This means energy savings for your home – and complete control over room temperature. Your home’s heating and cooling system won’t have to work so hard now that you’ve reduced most of the impact from the weather outside. If you want to feel some of the effects of the external elements, just move the louvers and adjust them to a preferred position. You can get more window treatment temperature control. Simply follow the instructions below to close your shutters properly. How to Close Your Shutters for Maximum Temperature Control There are two parts of your shutters that should be closed to seal off outdoor temperature: the louvers and the panels. To properly close your Polywood shutter panels, 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 properly close your louvers, push the tilt rod toward the louvers, making sure the top of the tilt rod will fit into the "mouse hole," which is above the top louver. Do this by running your hand up the tilt rod, and push in as you go up. This is particularly true for taller shutters. Sometimes a soft push at the bottom of the tilt rod isn't enough and doesn’t close gaps at the top.
