SR208 Optimised wall-to-floor junctions in multi-storey, multi-residential light timber-framed buildings (2013)

Many research projects around the globe have considered acoustic, fire and structural solutions for multi-storey light timber-framed buildings. However, most have looked at these aspects in isolation, predominantly at the expense of the others. The need was identified to find optimum solutions covering all three disciplines.

This project has derived and verified by testing a selection of construction details for walls, floors and their joints in multi-storey timber-framed buildings that can be economically used to satisfy the New Zealand Building Code (NZBC) requirements for suppression of sound transmission, suppression of fire spread and provide the structural integrity. It presents details of construction that can be used to meet the performance requirements of clause G6 Airborne and impact sound.
