How Window Shutters Allow You to Control Room Temperature Closed shutters are the next best barrier against the variable temperature and wind in Cincinnati, coming right after windows. Window treatments such as shades, blinds, and draperies block most of the temperature from the outdoors, but not all. And, when you need a quality-made window treatment that gives you a cozy spot by the window, Polywood® shutters are your best product. We craft 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 diminishes heat transfer by 45.96%. This results in energy savings for your home – and total control over room temperature. The heating and cooling system in your home takes less time to work now that you have insulated against most of the impact from the weather outside. If you want to feel some of the effects of the external elements, simply tilt the louvers and adjust them the way you’d like. Get even more window treatment temperature control. Simply follow the instructions below to close your shutters all the way. How to Close Your Shutters for Optimal Temperature Control Two parts of your shutters need to be closed to seal off outside 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, check 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 and check that the top of the tilt rod fits into the "mouse hole," which is above the top louver. Do this by running 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.
