Calls to the BRANZ helplines have revealed confusion created by differing advice in NZS 3604:2011 on the ground clearance needed for particleboard flooring. What is the ground clearance needed?
When the flooring of a suspended timber-framed floor is particleboard, NZS 3604:2011 Timber-framed buildings specifies a minimum clearance of 550 mm between the underside of the particleboard and the ground (paragraph 2.3.7).
However, paragraph 188.8.131.52 in NZS 3604:2011 allows a minimum pile height above finished ground level of 150 mm. So, in what situations may minimum pile heights apply?
