Technical Details
For impact sound insulated floor structures, installation of impact sound insulation under wedi Fundo and perimeter isolation strips should be planned: Construction using wedi Nonstep Plan impact sound deadening boards (6 mm rubber granulate insulation element, Δ L W,R = 14 dB in accordance with DIN 52210). Alternatively, approved polythene membranes may be used.
Permitted noise level in accordance with DIN 4109 LIn ≤ 30 dB(A) and in accordance with VDI 4100 SSt III ≤ 25 dB (A), caused by water installations: complied with using wedi Fundo and Nonstep Plan.
wedi Fundo shower elements can be cut to size on site, the geometry of the elements should be maintained however. wedi Fundo shower elements can only be combined with the wedi Fundo drains.
