How Window Shutters Give You Control Over Room Temperature Closed shutters are the next best defence against the extreme temperature and wind in San Diego, coming right after windows. Window treatments such as shades, blinds, and draperies block most of the temperature from the outdoors, not all. And, where your window treatment’s quality means the difference between a cozy seat next to the window and one that’s not, Polywood® shutters are the preferred product. Polywood shutters are built from a synthetic polymer that insulates up to 70% better than a comparable traditional wood shutter. As a matter of 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 wallet – and total room temperature control. Your home’s heating and cooling system won’t have to work so hard now that you’ve blocked off most of the impact from the outside weather. 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 a preferred position. You can get more window treatment temperature control. All you have to do is close your shutters all the way. How to Close Your Shutters for Maximum 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 properly close your Polywood shutter panels, swing them toward the window. As you move the panels into the shutter frame, make sure to interlock the pieces of weatherstripping along the vertical ends of your shutters. To properly close your louvers, push the tilt rod toward the louvers, making sure the top of the tilt rod fits into the “mouse hole” just above the top louver. Do this by running your hand up the tilt rod, pushing in as you go. This is especially true for taller shutters. Sometimes a soft push at the bottom of the tilt rod isn't enough and can leave gaps at the top.
