Primacoustic PrimaBlock is a heavy bariumim pregnated vinyl that is mounted inside the wall structure to help reduce sound transmission. This 1lb/psf emulates the weight of lead without the toxicity concerns. The 54” width provides a 6” overlap when tacking two rows together to create a 96” width. To install, loosely suspend between studs using staples and apply gypsum board directly on top. Roll size: 54” x 30’ (1.4m x 9.15m) Coverage: 135 ft2 (12.5m2).
