How Window Shutters Allow You to Control Room Temperature Closed shutters are the next best barrier against the extreme temperature and wind in Boise, coming right after windows. Window treatments such as blinds, shades, and draperies block most of the external temperature, not all. And, when you need a sturdy window treatment that gives you a comfortable spot next to the window, Polywood® shutters are the optimal product. Polywood shutters are built from a synthetic polymer that insulates up to 70% better than a similar traditional wood shutter. In fact, the Polywood Shutter Insulating System blocks as much as 30 degrees of airflow and lessens heat transfer by 45.96%. This means energy savings for you – and total control over room temperature. 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 bring in some of the effects of the external elements, simply slant the louvers and adjust them the way you’d like. You can get even more window treatment temperature control by closing 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 louvers and the panels. 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 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. The best way to do that is to run your hand up the tilt rod, and push in as you go up. This is especially true for taller shutters: sometimes a small push at the bottom of the tilt rod isn't enough and leaves gaps at the top.
