Intermediate Floor System
EGGER can achieve sound reduction of 44 dB with 22 mm EGGER Protect, a 15 mm plasterboard ceiling and 220 mm
IWS-Joists at 600 mm centres
In addition to meeting the UK acoustic performance regulations, this minimum specification solution offers cost
savings in both materials and installation:
- No insulation – Potential savings – £4 m2 materials PLUS £4 m2 installation costs = £8 m2
- No resilient bars – Potential savings – £4 m2 materials PLUS £4 m2 installation costs = £8 m2
- Shallow floors – overall depth 257 mm – Joists can be treated with IWS-FR (at no extra cost) to provide excellent fire mitigation properties (fully compliant with WPA Benchmark FR Build quality scheme). IWS-FR has a distinctive purple colour.
- Only engineered joist on the market pre-treated to significantly reduce water ingress. This allows it to retain its strength and straightness characteristics both during and after the build process.
