How Window Shutters Allow You to Control Room Temperature When closed, shutters become the next best barricade against Charlotte’s wind and variable temperatures – after your windows. Other window treatments such as blinds, draperies, and shades block most of the temperature from outside, 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 build 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 as much as 30 degrees of airflow and diminishes heat transfer by 45.96%. This results in energy savings for you – and complete room temperature control. Your home’s heating and cooling system won’t have to work so hard now that you have blocked off most of the impact from the outside weather. If you want to feel some of the effects of the external elements, simply 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 all the way. How to Close Your Shutters for Complete Temperature Control Two parts of your shutters need to be closed to seal off outside 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, make sure to interlock the pieces of weatherstripping along the vertical ends of your shutters. To close your louvers properly, push the tilt rod toward the louvers, checking that the top of the tilt rod will fit into the "mouse hole," which is above the top louver. It is best to run your hand up the tilt rod, pushing in as you go. This is especially true for taller shutters: sometimes a soft push at the bottom of the tilt rod isn't enough and leaves gaps at the top.
