How Window Shutters Help You Control Room Temperature Closed shutters are the next best defence against the extreme temperature and wind in Cleveland, coming right after windows. Window treatments such as blinds, shades, and draperies block most of the external temperature, not all. And, where your window treatment’s quality means the difference between a pleasant seat by the window and one that’s not, Polywood® shutters are your best choice. Polywood shutters are crafted from a synthetic polymer that insulates 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 reduces heat transfer by 45.96%. This translates into energy savings for your house – and full control over room temperature. Your home’s heating and cooling system will work faster now that you have insulated against most of the impact from the weather outside. If you want to let in some of the light and be more exposed to the outside temperature, just tilt the louvers open and adjust them the way you’d like. You can get more window treatment temperature control by closing your shutters completely. How to Close Your Shutters for Maximum Temperature Control Two parts of your shutters should be closed to seal off outside 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, 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 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, pushing in as you go. This is especially true for taller shutters – sometimes a small push at the bottom of the tilt rod isn't enough and can leave gaps at the top.
