How Window Shutters Help You Control Room Temperature When closed, shutters become the next best barricade against Hartford’s wind and extreme temperatures – after your windows. Window treatments such as blinds, shades, and draperies block most of the external temperature, but not all. And, when you need a quality-made window treatment that gives you a comfortable spot next to the window, Polywood® shutters are the optimal product. We make Polywood shutters from a synthetic polymer. Polywood shutters insulate up to 70% better than a comparable traditional wood shutter. In fact, the Polywood Shutter Insulating System blocks as much as 30 degrees of airflow and diminishes heat transfer by 45.96%. This means energy savings for your house – and total control over room temperature. The heating and cooling system in your house won’t have to work so hard now that you’ve blocked off most of the impact from the weather outside. If you want to bring in some of the light and be more exposed to the outside temperature, simply tilt the louvers and adjust them to a preferred position. Get more window treatment temperature control. All you have to do is close your shutters properly. How to Close Your Shutters for Optimal Temperature Control There are two parts of your shutters that need to be closed to seal off outdoor temperature: the louvers and the panels. 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 properly close your louvers, push the tilt rod toward the louvers and ensure that the top of the tilt rod will fit into the "mouse hole," which is 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 particularly true for taller shutters. Sometimes a soft push at the bottom of the tilt rod isn't enough and can leave gaps at the top.
