SOLID HARDWOOD FLOORING
Acoustic in floor constructions
Commercial / Residential / Sport
The Specifier's Information describes recommended values for step sound reduction and absorption coefficients for a wide range of Junckers flooring systems.
For general information on sound and practical guidelines on acoustics in floor constructions with Junckers solid hardwood flooring see E 5.0.
Furthermore, reference made to Junckers floor systems see C 1.0 and D 1.0.

In multi story residential buildings, hotels, student hostels, residential care homes, etc. national building regulations normally require a certain step-sound level between dividing floors in two units.
Reference is made to national building regulations.
For recommended step-sound reduction values for selected Junckers floor systems: See Table 1.
|Table 2||Frekvens, Hz|
|Absorption coefficients for selected floor systems||125||250||500||1000||2000||4000|
|22 / 20,5 mm batten system with soft packing on concrete||0.15||0.11||0.10||0.07||0.06||0.07|
|22 / 20,5 mm clip system with PolyFoam on concrete||0.02||0.19||0.04||0.02||0.04||0.05|
|14 mm clip system with PolyFoam on concrete||0.01||0.13||0.07||0.02||0.03||0.01|
Table 2 shows recommended absorption coefficients in the frequency range 125- 4,000 Hz for selected floor systems. For calculation of reverberation time.
