Farm Forestry Timbers
In this newsletter:
Annual General Meeting, Tahuna Conference Centre, 5-6 pm 6th May 2018
The last year has been a busy and hopefully productive year for me as the Farm Forestry representative on three important standards committees that relate to use of timber in construction. Two of these standards have made it to the public comment stage and I'm hoping will be done and dusted before the end of the year. These are NZS 3640 which is about chemical preservation of timber, and the closely related NZS 3602, which provides "acceptable solutions" in terms of durability performance for a range of applications. This is a particularly important standard for our specialty timbers because it allows different species to be used in a range of applications from timber decking and flooring to cladding and structural applications such as beams, rafters and framing. What this experience has shown me is just how much work we need to do to allow many of our naturally durable timbers into applications they are well suited to. Because I also sit on the Specialty Wood Products Partnership technical committee, I expect to feed those requirements into formulating research that will give us the evidence of durability performance that we need for entry into future revisions of that standard. I'm also hoping for a number of new introductions into the standard this time around, based on history of use and other evidence proving suitability. Natural durability has a market, and recognition as an acceptable solution means councils can't reject our timber for that application. However, until then many architects and specifiers believe they have only one choice, treated radiata pine. Only once the standards are published will any changes I have been lobbying for come into effect. A more inclusive standard would be a sermon to preach, a message worth delivering to those who should know that natural timbers have a place in the market.
