How Window Shutters Allow You to Control Room Temperature When closed, shutters become the next best defence against New Brunswick’s wind and extreme temperatures – after your windows. Other window treatments such as blinds, draperies, and shades block most of the temperature from outside, not all. And, when you need a sturdy window treatment that gives you a pleasant seat by the window, Polywood® shutters are the preferred product. Polywood shutters are built from a synthetic polymer that insulates up to 70% better than an equivalent traditional wood shutter. In fact, the Polywood Shutter Insulating System blocks as much as 30 degrees of airflow and lessens heat transfer by 45.96%. This results in energy savings for your house – and complete control over room temperature. The heating and cooling system in your residence won’t have to work so hard 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, simply slant 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 completely. How to Close Your Shutters for Complete Temperature Control There are two parts of your shutters that should 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 move 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, checking that 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 also 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.
