Absolutely, well worth purchase! We purchased acoustic grade Indow inserts to block some of the construction noise and workers music. It has drastically improved our quality of life. At times we are quite suprised of the difference in noise environment between the outside of our home and living area Indow inserts are located in. We are currently awaiting delivery of our second order of Indow inserts for 2 additional rooms.
Although, they are pricey they are worth the purchase.
