PBM Concrete Acoustic Blocks are specifically designed to reduce noise transmission in construction projects, providing effective sound insulation. Measuring 390(L) x 190(H) x 140(D) mm, these blocks feature a unique profile with 3 slots on the face, allowing sound to travel into the hollow cores for enhanced acoustic performance. Commonly used alongside PBM Hollow Blocks and PBM Split Face Blocks, they create a robust, sound-insulating concrete wall or fence.
