How Window Shutters Allow You to Control Room Temperature Closed shutters are the next best defence against the variable temperature and wind in San Antonio, coming right after windows. Window treatments such as shades, blinds, and draperies block most of the temperature from the outdoors, not all. And, where a sturdy window treatment means the difference between a comfortable seat next to the window and one that’s not, Polywood® shutters are the preferred choice. We craft Polywood shutters from a synthetic polymer. Polywood shutters insulate up to 70% better than a similarl traditional wood shutter. As a matter of fact, the Polywood Shutter Insulating System blocks up to 30 degrees of airflow and diminishes heat transfer by 45.96%. This results in energy savings for your wallet – and complete control over room temperature. Your home’s HVAC system will work faster now that you have blocked off the impact from the outside weather. When you want to feel some of the light and be more exposed to the outside temperature, just slant the louvers open and adjust them to a preferred position. Get more window treatment temperature control by closing your shutters completely. How to Close Your Shutters for Optimal 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 move the panels into the shutter frame, check that the pieces of weatherstripping interlock along the vertical ends of your shutters. To close your louvers properly, push the tilt rod toward the louvers and check that the top of the tilt rod will fit into the "mouse hole," which is above the top louver. Do this by running your hand up the tilt rod, and push in as you go up. 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.
