One of the problem Elephant Board has is that the bracing system fixing at the flooring in 3604 is taken straight from the Braceline manual but is patented to Winstones so they have to use a different hold down system. Some councils have accepted it as an alterative solution but others haven't. Even with councils, some building officers accept it, others haven't. It just not worth going to MBIE for a decision on it so most designers won't specify it.Elephant board is alive and well after 30 years of battling with Winstone.
I understand James Hardie Ltd, the supplier of the cladding mostly associated with leaky homes was the sponsor of BRANZ for years, maybe still is.
People think there is no corruption in NZ, there is. It is just not brown envelopes as is the case elsewhere.
