Flat sound insulation blocks
High sound insulation and high degree of block compressive stress / Approval Z-17.1-459
KLB flat sound dampening blocks are solid full blocks without slots or chambers and with a particularly high block gross density. In addition to the provided high sound insulation they offer high block compressive stress and also a corresponding high wall load-bearing ability. Depending on their block gross density, KLB flat sound insulation blocks are used for house separation walls of townhouses or duplexes or for apartment separation walls or stairwell walls.
KLB flat sound insulation blocks comply with DIN V 18152-100 and are additionally approved by the building authority, Approval Z-17.1-459.
