Aerofiber MagTuff and MagRift are magnesium oxide (MgO) based, non-insulating sheathing boards and tiles, with much improved characteristics such as fire resistance, weatherability, strength and resistance to mildew. These are new generation, high performance, eco-friendly systems completely free of toxins (asbestos, formaldehyde or silica) has no odour and releases that may affect the environment and do not emit any hazardous substance even when exposed to high temperatures. MagTuff and MagRift consists of natural mineral ingredients only and are completely free of any toxins. These eco-friendly ingredients are Magnesium oxide (MgO), magnesium chloride (MgCl), perlite (SiO2), fiberglass scrim, cellulose, proprietary additives etc. Magnesium oxide, the main ingredient of MagTuff and MagRift, are made from natural minerals which is widely used in medicine, food industry, water purifying systems and its antiseptic properties helps in prevention of mildew growth. When working and handling MagTuff and MagRift the dust produced is not so much so as to cause any inhalation irritation. By adapting recycled and pollution-free natural material, it surely meets the requirements of environmental protection.

Aerofiber MagTuff and MagRift are water resistant and virtually impervious to water (not more than 0.34 weight %). Aerofiber MagTuff MagRift are insoluble in water and prevents delamination of the board as well as swelling after long- term exposure to water.

MagTuff and MagRift are fire-resistant, non-combustible products with fire rating classified as Non-flammable Class A1 to European standards. High fire resistance of Aerofiber MagTuff and MagRift prevents fire and flame spread thus ensuring safety. Non-flammable A-class material is adopted and hence will not burn. The system limitation of fire endurance is up to 4 hours. At high temperature Aerofiber MagTuff and MagRift do not emit any toxicants or stifling smoke.
