Assessment and Technical Investigations The following is a summary of the assessment and technical investigations carried out on Earthwool Acoustic Floor Slab and Earthwool Acoustic Floor Slab Plus. Design Considerations 3 General 3.1 Earthwool Acoustic Floor Slab and Earthwool Acoustic Floor Slab Plus are used as a resilient layer for acoustic insulation of intermediate timber-based separating floors and intermediate concrete floors respectively, and are also effective in reducing the thermal transmittance (U value) of new or existing concrete floors, when used as a double layer. 3.2 Earthwool Acoustic Floor Slab is a suitable resilient layer in timber platform floors, Type 3 in new build and Floor Treatment/Type 2 in conversions and Earthwool Acoustic Floor Slab Plus is suitable in FFT4 in E-FC-1 and E-FC-2 Robust Details. 3.3 The slabs must not be used where they may come into contact with moisture from the ground. 3.4 Ground-supported concrete floors incorporating the slabs must include a suitable damp-proof membrane laid in accordance with the relevant clauses of CP 102 : 1973, BS 8102 : 1990 and/or BS 8215 : 1991. 3.5 Suspended concrete ground floors incorporating the boards must include a damp-proof membrane or suitable ventilation of the sub-floor as appropriate. 3.6 The overlay to the slabs should be: a cement-based floor screed, laid in accordance with the relevant clauses of BS 8204-1 : 2003 and/or BS 8204-2 : 2003, and BS 8000-9 : 2003, or wood-based floor, eg tongue-and-groove, flooring grade particle board (Type P5 or P7) to BS EN 312 : 2003 or oriented strand board of type OSB/3 or OSB/4 to BS EN 300 : 2006, 18 mm thick (minimum), installed in accordance with DD CEN/TS 12872:2007, or a concrete slab in accordance with BS 8204-1 : 2003 and BS 8204-2 : 2003.
