How Window Shutters Help You Control Room Temperature When closed, shutters become the next best barrier against Boston’s wind and variable temperatures – after your windows. Other window treatments such as blinds, shades, and draperies block most of the external temperature, but not all. And, where your window treatment’s quality means the difference between a comfortable seat next to the window and one that’s not, Polywood® shutters are the optimal product. We craft Polywood shutters from a synthetic polymer that insulates up to 70% better than a similarl 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 results in energy savings for your house – and complete control over room temperature. The heating and cooling system in your residence won’t have to work so hard now that you’ve insulated against the impact from the outside weather. If you want to feel some of the effects of the external elements, simply move the louvers open and adjust them to a preferred position. Get even 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 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, 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 ensure that the top of the tilt rod fits 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 also true for taller shutters. Sometimes a little push at the bottom of the tilt rod isn't enough and doesn’t close gaps at the top.
