AQUAPANEL® Cement Board Outdoor is a robust, non-combustible building panel made of aggregated Portland cement with coated glass fibre mesh embedded in back and front surfaces. It offers all the benefits of a dry panel system with the strength of brick and block. The ends are cut square and edges are reinforced for extra strength (the EasyEdge®). The panel provides a solid base that withstands extreme weather conditions


AQUAPANEL® Cement Board Outdoor is used is used in exterior applications for walls and ceilings as a directly-applied (water-managed) or ventilated system. Furthermore, AQUAPANEL® Cement Board Outdoor can also serve as a substrate for ceramic and other linings as well as thermal insulation composite systems (ETICS). European technical approval ETA-07/0173 has been issued for AQUAPANEL® Cement Board Outdoor. The panel is also certified according to the criteria of the Institute for Building Biology in Rosenheim, Germany, report no. 3006-214.
