How Window Shutters Help You Control Room Temperature When closed, shutters become the next best barricade against Indianapolis’s wind and variable temperatures – after your windows. Other window treatments such as blinds, draperies, and shades block most of the external temperature, not all. And, when you need a quality-made window treatment that gives you a cozy seat by the window, Polywood® shutters are your best product. Polywood shutters are crafted 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 up to 30 degrees of airflow and reduces heat transfer by 45.96%. This means energy savings for you – and total control over room temperature. 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, simply slant the louvers open and adjust them the way you’d like. Get even more window treatment temperature control by closing your shutters completely. How to Close Your Shutters for Complete Temperature Control There are two parts of your shutters that need to be closed to seal off outside 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 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. It is best to run your hand up the tilt rod, pushing in as you go. This is particularly 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.
