How Window Shutters Give You Control Over Room Temperature When closed, shutters become the next best barrier against Nashville’s wind and extreme temperatures – after your windows. Other window treatments such as blinds, draperies, and shades block most of the external temperature, but not all. And, when you need a sturdy window treatment that gives you a cozy seat by the window, Polywood® shutters are the preferred product. We build Polywood shutters from a synthetic polymer. Polywood shutters insulate up to 70% better than a similarl traditional wood shutter. As a matter of fact, the Polywood Shutter Insulating System blocks up to 30 degrees of airflow and reduces heat transfer by 45.96%. This translates into energy savings for your house – and complete room temperature control. Your home’s HVAC system will work faster since you’ve now blocked off the impact from the outside weather. When you want to let in some of the effects of the external elements, just slant the louvers 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 Complete Temperature Control Two parts of your shutters need to be closed to seal off external temperature: the panels and the louvers. To close your Polywood shutter panels properly, 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 fits into the "mouse hole," which is above the top louver. It is best to run your hand up the tilt rod, and push in as you go up. This is particularly true for taller shutters. Sometimes a little push at the bottom of the tilt rod isn't enough and can leave gaps at the top.
