MAGNESIUM-OXIDE BOARDS CAUSE MOISTURE DAMAGE INSIDE Magnesium oxide board, “MgO-board”, is a factory-made sheathing board product, which has been widely used in the last 5 years in ventilated facades on new or renovated buildings in Denmark. In winter 2014/15, a number of problems began to appear with these boards since the boards and adjoining building elements seemed to suffer from some sort of disease, which manifested itself by damages such as significant moisture, boards leaking salty water (‘tears’),corrosion of fittings and anchors and mould growth.
Figure 1: Sketch of a typical façade construction where a sheathing board is used as wind barrier. Adapted from [1]. Figure 2: Photo of 8 mm thick MgO-board with a glass fibre mesh on both surfaces. The observed damages were caused by the fact that MgO-boards absorb moisture from outside air. Water drops containing chloride ions appear on the outside of the boards – often so many that they run down the vertical boards and out via the air gap behind the siding boards (see Figures 4 and 5). The metal mountings for the MgO-boards can corrode heavily within a few years, cf. Figure 6.
Figure 5: The water drops containing chloride ions run down the vertical MgO-boards and drain out of the wall from behind the wall’s siding boards. Figure 6: The zink covering of the steel profile is corroded as a result of direct contact with salty sweat or ‘tear’ drops from the adjacent MgO-board.
