A few variables affect a window treatment’s R-value: form and substance. First, coverings that have an ample amount of avenues for heat to escape will not have a substantial R-value. For instance, blinds and curtains don’t firmly cover the window, allowing air to escape around the sides of the covering. However, interior shutters are custom-made snuggly around the window, trapping air against the window’s glass when the louvers are completely shut.

Secondly, what the window treatment is constructed with can have a huge impact to insulation. Take cell shades, which feature several ​​engineered layers of fabric designed to trap hot air. As a result, they should block air disbursement more efficiently than coverings like Roman shades. Likewise, Polywood louvered shutters, built from a impenetrable faux wood material, can repel heat loss more than more porous wood shutters. Polywood shutters also has weatherstripping, which results in a snug seal sound your windows when the panels and louvers are shut.
