H3.2 Exterior Cladding Systems

Weatherboards, Fascia, Box Corners, Scribers, Finishing Boards D4S and Cavity Battens

The experience of our primary staff saw a desperate need for an H3.2 exterior cladding system in the building sector. So we developed our Generation 2 exterior product range to meet such a need.

The MicroPro® (MCA) H3.2 treatment is applied to the wood using a high pressure treatment process. This allows deep penetration into the wood fibres allowing a 100% uptake of the treatment chemical.

We know you will enjoy using a 50-year-treatment-warrantied product on your home or your clients' home as much as we have enjoyed bringing an H3.2 100% treated product to the market.
