How Window Shutters Allow You to Control Room Temperature Closed shutters are the next best barrier against the variable temperature and wind in New York City, coming right after windows. Window treatments such as blinds, shades, and draperies block most of the external temperature, but not all. And, when you need a sturdy window treatment that gives you a comfortable spot by the window, Polywood® shutters are your best choice. Polywood shutters are built 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 lessens heat transfer by 45.96%. This translates into energy savings for your house – and full room temperature control. Your home’s HVAC system will work faster now that you’ve blocked off the impact from the weather outside. When you want to bring in some of the effects of the external elements, just slant the louvers open and adjust them to a preferred position. You can 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 should 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 push 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, making sure 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 also 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.
