I have been playing with 4 ft x 10 ft panels of Owen Corning 800 1.5 inch rigid duct insulation for the past 4 months. When placed at first reflection point on window there is a noticeable improvement. NRC of panel is around .85, so A little better than cellular shades are supposed to be. Just can not find any test data to confirm cellular and solar shades performance and thought someone may have experience with solar and cellular for comparison.
Solar/cellular shades -acoustical treatment
My right speaker is about 5 feet(ft) from the sliding glass doors (8 ft high by 16 ft wide) and is presently covered by solar shades. I have slap echo and reverb issues in the room and this is my first reflection point. I wanted to tackle this issue first when planning my acoustical treatment.
I have been told that solar shades have an NRC of about 0.15 so I was thinking of adding a set of cellular shades which I have been told has an NRC of 0.7. However, before investing a few thousand dollars I thought of asking if anyone had any experience with cellular shades and their acoustical absorptive performance. Manufacturers have not be able to provide any test data concerning acoustical performance. Also, any thoughts on any manufacturers' product acoustically better than the other.
thanks
