How Window Shutters Allow You to Control Room Temperature Closed shutters are the next best barrier against the variable temperature and wind in Honolulu, coming right after windows. Other window treatments such as shades, blinds, and draperies block most of the temperature from outside, but not all. And, when you need a quality-made window treatment that gives you a pleasant seat by the window, Polywood® shutters are the optimal product. We craft 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 lessens heat transfer by 45.96%. This translates into energy savings for your wallet – and full room temperature control. Your home’s heating and cooling system won’t have to work so hard now that you’ve blocked off the impact from the weather outside. If you want to let in some of the effects of the external elements, just tilt the louvers open and adjust them the way you’d like. You can get even more window treatment temperature control. All you have to do is close your shutters all the way. How to Close Your Shutters for Complete Temperature Control Two parts of your shutters ought to be closed to seal off outdoor temperature: the panels and the louvers. To close your Polywood shutter panels properly, swing them toward the window. As you move the panels into the shutter frame, ensure 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, ensuring 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 also true for taller shutters – sometimes a little push at the bottom of the tilt rod isn't enough and leaves gaps at the top.
