How Window Shutters Give You Control Over Room Temperature Closed shutters are the next best barrier against the variable temperature and wind in Kingsport, coming right after windows. Window treatments such as blinds, draperies, and shades block most of the external temperature, not all. And, when you need a quality-made window treatment that gives you a pleasant seat by the window, Polywood® shutters are the optimal product. We make Polywood shutters from a synthetic polymer that insulates up to 70% better than a comparable traditional wood shutter. As a matter of fact, the Polywood Shutter Insulating System blocks up to 30 degrees of airflow and reduces heat transfer by 45.96%. This results in energy savings for your house – and complete control over room temperature. Your home’s heating and cooling system won’t have to work so hard now that you’ve blocked off the impact from the weather outside. If you want to feel some of the light and be more exposed to the outside temperature, simply tilt the louvers open and adjust them to a preferred position. Get even more window treatment temperature control. Simply follow the instructions below to close your shutters properly. How to Close Your Shutters for Maximum Temperature Control Two parts of your shutters need to be closed to seal off external temperature: the panels and the louvers. To properly close your Polywood shutter panels, swing them toward the window. As you push the panels into the shutter frame, make sure to interlock the pieces of weatherstripping along the vertical ends of your shutters. To properly close your louvers, push the tilt rod toward the louvers and ensure that the top of the tilt rod will fit into the “mouse hole” just above the top louver. The best way to do that is to run 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 leaves gaps at the top.
