Stabilising floor joists
By Roger Shelton – 1 June 2019, Build 172
Where is blocking required to stabilise floor joists? We look to NZS 3604:2011 Timber-framed buildings for answers.
E3/AS1 and wet area flooring
By Bruce Sedcole – 1 October 2021, Build 186
From 4 November 2021, there will no longer be an Acceptable Solution in Building Code clause E3 Internal moisture for using timber or timber based products as linings and finishes to floors in wet areas. However, an Alternative Solution designed and specified to best practice is easy to do.
Inter-tenancy floors in MDH
