Browse Forums Building A New House 1 Dec 07, 2020 12:08 am Hi everyone, We are building a double story house in Sydney. We have fibre cement weatherboards as the external walls on the first floor. The builder's standard method of installation for weatherboards is direct fix. We aren't sure if direct fix is the best method or it is just an easy/cost-effective way that the builder prefers. Does anyone know which installation method is better (direct fix or cavity battens) and why? Also, for improving the sound insulation of the wall system the builder has proposed the following wall system (from inside to outside). Timber framing (with R2.5 batts), HardieWrap (vapour permeable barrier), HardieFlex (6mm fibre cement sheet), battens and Linea weatherboard. Does anyone see any problem with the above wall system? (e.g. condensation, moisture trap, being prone to mould)? There is no gap between HardieWrap and HardieFlex, does it negatively impact the performance of the vapour permeable barrier (HardieWrap)? Thanks in advance Hey guys, what’s everyone opinion on James Hardie linea direct fix to frame? Would this be the most common method and anybody ever had any problems down the track? 0 5151 Thanks Simon, I guess I'm no concerned with the volume of the noise rather that dead and hollow sound and feel that is associated with floating floors. But I'm not sure… 3 6156 2 5943 |
