KLB-Flat-Hollow Wall Panel

Light-weight separation wall blocks for non-load-bearing walls

KLB flat hollow wall panels can be used in addition to 8 DF flat solid blocks as light-weight separation blocks for non-load-bearing walls, for partitions or surrounds. KLB-flat-hollow wall panels have the same butt joint gears as the flat-building panel. The load-bearing joint is formed in the hollow wall panels using the thin-bed process, while the butt joint remains free of mortar.

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
