Timber construction in NZ utilising effective sound insulation

We have addressed the fact that current NZ construction is not achieving a level of sound control (especially impact) thatsatisfies a majority of occupants. In this we are not unique.Other timber oriented regions (North America and Scandinavia) have been working for several years to find solutions and theresults from some of their trial buildings we have included here. These results could be showing NZ a direction to follow.Unfortunately we cannot directly transpose these results to our own situation and only testing with NZ materials fixed in amanner to suit our own style of framing will ensure we have long term answers.
