The New Zealand construction industry is moving away from solvent based treatments, with H3.1 no longer an acceptable solution for solid timber framing, and Lumberworx is leading the charge for engineered wood products suppliers.
Lumberworx supplies all its products at H1.2 and has produced a helpful bulletin to help everyone get up to speed with the changes.
The Lumberworx I-Beam (LIB) is treated to H1.2 hazard class. This is achieved by fabricating with all components treated to H1.2 by full penetration methods to the retention levels prescribed in NZS3640:2003 (including amendment 5). The LIB can be installed within the building envelope wherever H1.2 hazard class is specified in NZS3602:2003. This includes sub floor, mid floor and roof spaces, while also being fit for purpose under wet areas.
The H1.2 treatment is a New Zealand first for I-Beams, and is another step in eliminating solvent based treatments from the building site.
