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.

*) plastered, inside with 15 mm gypsum light-weight plaster λR = 0.35 W/mK, outside with 20 mm mineral fibre light-weight plaster λR = 0.31 W/mK

- not applicable, not standard

1) higher weight possible depending on weather

2) 1 = basement masonry, 2 = exterior masonry, 3 = back-up masonry, 4 = interior masonry, 5 = light-weight separation wall, 6 = statically stressed masonry, 7 = sound insulating masonry, with addition “x” = supplementary block

3) time for m² with offset aid, as blocks are > 25 kg
