Roof Space Ventilation MAGNÉSIOPAN Board will give many years of satisfactory performance under a wide range of climatic conditions, but to ensure long term performance to both lining material and pain finishes, the rood spaces should be adequately ventilated. Failure to do so may cause excessive moisture movement of timber framing causing popping or joint deformation. Design Considerations The aluminium foil sarking on roofs should be installed in accordance with the relevant Australian Standards for Levels of Finish reflective foil laminates. Vapour barriers are incorporated into the structure to prevent the flow of water vapour from the warm to the cool regions. As a general rule, locate the vapour barrier as close as possible to the surface which is normally be at the higher temperature at the time of the condensation hazard.

Joint Location Where possible it is recommended that full length sheets are used to minimise butt joints at sheet ends. Sheets should be butted firmly together, but not forced. Where butt joints at sheet ends are unavoidable and where jointing between framing members is not required, as per Table 2, 3 and 4, butt joints may be formed on a framing member, provided that the framing member has a bearing face equal to or greater than 35mm width for nail fixing or 32mm width for screw fixing.

Control joints are to be installed: In long partition or wall runs, at no more than 12m centres. To coincide with control joints in the supporting frame. The continuity of MAGNÉSIOPAN and support framework should be broken at control joints. In continuous ceiling areas, spaced at no more than 12m centres in both directions.
