IBuilt CoreClad panels are manufactured from both Hoop Pine and Klinkii Pine, which have been grown from sustainably managed plantation forests.
Individual veneers are ACQ treated to meet hazard class H3.2 and then manufactured into plywood sheets by bonding the treated veneers with a Type A structural marine bond. The plywood sheets are machined, band sawn, grooved (if required) and ship-lapped to form the finished cladding panel.
The manufacture of IBuilt CoreClad is third party certified by EWPAA to meet AS/NZS 2269:2012-Plywood Structural Standard.
