Description
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.
Queries are starting to come in to the BRANZ helpline about upcoming changes to E3/AS1, specifically the flooring options that will be available for household wet areas such as kitchens, bathrooms, laundries and toilet facilities.
Currently, both E3/AS1 Amendments 6 and 7 are a means of compliance during the transition period from 5 November 2020. However, from 4 November 2021, only E3/AS1 Amendment 7 can be used as a means of compliance.
Scope
This article includes:
- Flooring options in Amendment 6
- Submissions on proposed changes
- Fewer options – no timber or timber based products
- Timber systems in wet areas
- Alternative Solution is a good option
