The Amendment allows the use of Boron for H3.1 treatment of timber, and was developed using a very thorough process, Mr Steele says. “The Department, which was represented on the committee that developed the Amendment, has stated that it supports the greater use of Boron treatments.
Concern expressed “It has expressed some concern about practical issues relating to the use of this treated timber in houses, such as compatibility of treated timber with wallboard adhesives and building underlays.
“This refl ects the Department’s responsibility for considering these issues in the broader context of the New Zealand Building Code,” Mr Steele says “These issues are not just related to Boron treatment but to a wide range of timber treatments, and are not within the scope of the timber treatment Standard.
“The committee recognised that these issues would need to be addressed within other related Standards, and specifi cally asked Standards New Zealand to progress this. “We are now in discussions with the Department about initiating a full review of Standards related to timber treatment.
This recognises the Department’s role with respect to the New Zealand Building Code and Standards New Zealand’s role to provide Standards which support the Code. “We are committed to publishing Standards which contribute to raising the quality of building construction in New Zealand,” Mr Steele says.
