¹ Construction height based on Fermacell thickness, excludes floor finish.
² Excludes floor finish.
³ Part L compliant for floors above heated rooms.
⁴ Dependent on joist integrity.
Area of Application:
- Floors with rooms of equal temperature above and below, and a minimum R-value of 0.75 m² K / W.
- This construction is suitable for use on intermediate floors, no further insulation is needed to meet the Part L requirements.
Additional Information:
- When installed, the Fermacell elements may follow any undulation that occurs from the joists. This may need to be taken out with the use of a thin levelling compound.
- Glue and screw supporting ply to battens.
- Aluminium diffuser plates should be flush with the top of the joists.
- Minimum 100 kg / m³ mineral wood.
- Ceiling must be suspended e.g. typical metal frame system.
- Airborne DnTw + Ctr: 55 dB (≥ 43 dB required).
- Impact LnTw: 44 dB (≤ 64 dB required).
