How Window Shutters Allow You to Control Room Temperature When closed, shutters become the next best barricade against Chicago’s wind and extreme temperatures – after your windows. Other window treatments such as blinds, shades, and draperies block most of the temperature from the outdoors, but not all. And, when you need a sturdy window treatment that gives you a pleasant spot next to the window, Polywood® shutters are the preferred choice. We build Polywood shutters from a synthetic polymer. Polywood shutters insulate up to 70% better than an equivalent 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 results in energy savings for your wallet – and full control over room temperature. The heating and cooling system in your residence takes less time to work now that you have insulated against most of the impact from the outside weather. If you want to let in some of the light and be more exposed to the outside temperature, just move the louvers and adjust them to a preferred position. Get even more window treatment temperature control. All you have to do is close your shutters completely. How to Close Your Shutters for Maximum Temperature Control There are two parts of your shutters that need to be closed to seal off outside 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, 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 ensure that the top of the tilt rod fits into the “mouse hole” just above the top louver. Do this by running your hand up the tilt rod, pushing in as you go. This is particularly true for taller shutters: sometimes a small push at the bottom of the tilt rod isn't enough and doesn’t close gaps at the top.
