It is difficult to say if the thermal insulation or the sound reduction is better. Both are outstanding. I used an indoor-outdoor thermometer to measure the temp inside the shutters and outside the shutters. I measured a 6-degree C difference in the windows with the secondary glazing and those without. The noise reduction is significant. We live on a busy road with two bus routes and we are sleeping much better now with the 5 mm secondary glazing. In addition, I had to design and install a frame for the acrylic windows (240cm x 117cm). During the last storm we registered 90+ MPH winds. The windows/secondary glazing held up without any issues.
