How Window Shutters Allow You to Control Room Temperature Closed shutters are the next best barrier against the extreme temperature and wind in Dallas, coming right after windows. Window treatments such as blinds, draperies, and shades block most of the temperature from the outdoors, but not all. And, where your window treatment’s quality means the difference between a cozy seat by the window and one that’s not, Polywood® shutters are the preferred product. We make 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 means energy savings for you – and total control over room temperature. The heating and cooling system in your house takes less time to work now that you’ve insulated against the impact from the weather outside. If you want to let in some of the light and be more exposed to the outside temperature, simply tilt the louvers open and adjust them to how you’d like them. Get more window treatment temperature control by closing your shutters all the way. How to Close Your Shutters for Maximum Temperature Control Two parts of your shutters should be closed to seal off outdoor temperature: the panels and the louvers. To properly close your Polywood shutter panels, swing them toward the window. As you push 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 check 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, pushing in as you go. 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.
