The M4-Exterior Sheathing is Fibre reinforced, produced with composite materials as pure Magnesium Sulphate MgO expanded Perlite, other agents and strong alkali free glass fibre mesh. It is a 100% asbestos and silica free. The board appears in its natural off white colour as standard and has a hard and durable surface.

The M4-Exterior Sheathing has very limited moisture absorption from air humidity, compared to normal MgO boards, the board does not contain any chloride ion (salt), resulting in corrosion of screws – nails – windows etc. The board can absorb and release moisture an unlimited number of times, without changes in the board strength properties. The board is vapour permeable and insulation can be mounted directly on the backside, when used in ventilated constructions with closed vapour barrier.
RESISTANT TO TERMITES, MOLD AND FUNGUS The M4-Exterior Sheathing will not rot or degrade in humid environment. The PH value makes the board very resistant to attack by termites, fungus and mould.
APPLICATIONS Exterior Sheathing, SIPs. The panel is a very versatile and useful building board with very good racking resistance for both residential and commercial building construction. It is suitable for a wide range of general building usages and for applications requiring fire rating and non fire rating as well as termite, mold and mildew control.
