How Window Shutters Allow You to Control Room Temperature Closed shutters are the next best defence against the variable temperature and wind in Fort Myers, coming right after windows. Window treatments such as blinds, shades, and draperies block most of the temperature from outside, not all. And, where your window treatment’s quality means the difference between a pleasant seat next to 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 a similar 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 your house – and full control over room temperature. Your home’s heating and cooling system won’t have to work so hard since you’ve now insulated against the impact from the weather outside. When you want to let in some of the light and be more exposed to the outside temperature, simply move the louvers and adjust them to how you’d like them. Get even more window treatment temperature control. All you have to do is close your shutters completely. 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 close your Polywood shutter panels properly, 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 check 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 can leave gaps at the top.
