Apartment Living on a Four Lane Highway
We live in a senior apartment on a busy four lane highway. We purchased 7 sound proof windows plus a sliding glass door, and the reduction in the noise form this road has been dramatic. I would say a 90% reduction in the road noise . We have recommended sound proof windows to many of the residents in our building which has resulted in increased sales for this company. All report great happiness with their new windows. D & J H., Olympia WA.
