Durabarrier is available as 4.5mm and 6mm thick fibre cement sheets that have been sealed on the face and edges and are specifically manufactured to be used as a Rigid Sheathing.
Durabarrier has been BRANZ Appraised (Appraisal number 721 [2011]) and tested against the requirements of Table 23 of NZBC Acceptable Solution E2/AS1. Durabarrier is designed to resist high wind pressures in building facades where it creates a wind barrier which equalizes the pressures within the cavity to the external pressures.
