I spoke to some of the kennel employees this morning and lately we have had some more dogs coming in ,barkers and howlers . They have noticed a dampening down of the noise as they put it . I will tell you that installation went extremely well . We had the entire 60 panels put up in a little over one hour . And they look fantastic! They are barely noticeable and our ceiling is only 10 ft high. I’m so pleased with my purchase . Thank you for all your help . I would recommend this product , and the cost was not prohibitive.
