Our experience with Acoustiblok was absolutely positive and even exceeded our expectations. This hospital project had a severe acoustic problem due to the fact that the only feasible location for the chilled water plants (90 tons each) of the A/C system is right next to the building, specifically 4 feet apart from the intern’s dormitories!!!!!
Once the chillers were installed, the owner discovered that the high pitch (very uncomfortable) noise produced by the rotary screw compressors went through the structural concrete walls like nothing, measuring up to 67 dBA inside the dorms and adjacent areas.
With just 3 weeks prior to the deadline, I recommended a perimeter acoustical barrier wall to deflect sound out of the hospital walls, the wall was simply made out of Sheetrock and a single layer of Acoustiblok, it only took a week to finish it and we obtained an impressive 20 dbA sound transmission loss in that same areas.
Previous installed walls in similar applications made out of concrete or concrete and Styrofoam cost more time and money and are only half as efficient as the Acoustiblok solution, I definitively recommend to give Acoustiblok a try, you´ll be impressed, just like us!!!
