Impact sound deadening for uneven substrates: 16 dB
wedi Nonstep Plan impact sound deadening consists of a 6 mm wedi building board which is bonded in the factory to a 5 mm rubber matt resulting in an shiplap joint. The impact sound deadening board is used for the purposes of decoupling underneath ceramic floor coverings, laminate flooring or pre-fabricated parquet flooring.
Material base polyurethane-bonded recycled rubber material with styrofoam flakes and a special, flexible, mineral coating
Density - 600 kg/m3
Tear strength - 0,25 N/mm2
Compressive strength at 30% deformation - 0,65 N/mm2
Static rigidity s`= 56 MN/m3 at the linear start of the load deflection curve in accordance with DIN 53421
Dynamic rigidity s`= 97 MN/m3 from resonant frequency 35 Hz at 2000 kg/m2 in accordance with EN 29052
Temperature resistance - -40°C to 115°C
Fire behaviour - E in accordance with EN 13501
Impact sound deadening Δ L = 14 dB in accordance with DIN EN ISO 140-8 (tested on concrete ceiling, under tiles) W,R
For decoupling ceramic and natural stone floor coverings from the substructure
For deadening impact sound when laying ceramic and natural stone floor coverings with a relatively low design height
On all load-bearing surfaces such as concrete, wooden floorboards (not stairs)
Underlay for floating floor coverings such as ready-to-lay parquet or laminate
Not for use under electric thin-bed heating elements
For residential type use. Not approved for wheeled loads with high concentrated loads.
The surfaces must be even, clean, load-bearing, dry and free of vibrations. Level out any unevenness before laying. Make sure that wedi Nonstep Plan covers the entire area.
