How Window Shutters Help You Control Room Temperature Closed shutters are the next best barrier against the variable temperature and wind in Jacksonville, coming right after windows. Window treatments such as shades, blinds, and draperies block most of the external temperature, not all. And, where a sturdy window treatment means the difference between a pleasant seat by the window and one that’s not, Polywood® shutters are the optimal product. We make 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 as much as 30 degrees of airflow and reduces heat transfer by 45.96%. This translates into energy savings for your home – and total control over room temperature. Your home’s HVAC system won’t have to work so hard now that you’ve reduced most of the impact from the weather outside. When you want to feel some of the effects of the external elements, simply slant the louvers open and adjust them to how you’d like them. You can get more window treatment temperature control by closing your shutters properly. How to Close Your Shutters for Optimal Temperature Control There are two parts of your shutters that should 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 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, ensuring 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 soft push at the bottom of the tilt rod isn't enough and doesn’t close gaps at the top.
