Magnesium Oxide is a versatile material widely used in Asian residential and commercial buildings. Major,(magnesite) deposits are found in China, Middle East, and Canada. Egypt is one of the Middle East countries that mines magnesite. Magnesium Oxide wall cladding is a new technique in Egyptian construction field, some of Cairo’s modern buildings facades applied locally manufactured Magnesium Oxide wallboard as external shaping material. The research paper illustrates through site observations followed by a comparative study between Cairo’s traditional façade shaping technique using Cement Plaster on metal lath and using Magnesium Oxide wallboards, The research ends up by showing the advantages and disadvantages of using Magnesium Oxide wallboard for external claddings in Cairo.
Methodology:
Historical background about the use of Magnesium Oxide material as building façade cladding material.
Illustration of the environmental sustainability of Magnesium Oxide material.
Environmental and financial comparison of building facades shape forming traditional cement plaster on
expanded metal lath technique used in Cairo Egypt and external wall cladding using Magnesium Oxide wallboards.
Site investigation on the results of applying Magnesium Oxide wallboards as a new shape forming
technique in modern Cairo buildings showing its advantages and disadvantages and its application
capabilities in Cairo’s weather conditions.
Purpose and use:
Magnesium Oxide board is a factory-made, non-insulating sheathing board product. It can be used for a
number of interior or exterior applications including wall and ceiling linings, fascias, soffits, countertop, shaftliner
& area separation wall board, exterior sheathing, substrates for coatings and insulated systems such as:
direct-applied finish systems, (painting & Stucco), it can be used as tile backing and under laments.
Magnesium Oxide is widely used primarily as wallboard alternative to conventional gypsum-based drywall
–but with much improved characteristics such as fire resistance, weather ability, strength, resistance to mold and
mildew and so on. The Magnesium Oxide boards can be scored and snapped, sawed, drilled and fastened to
wood or steel framing. Magnesium Oxide boards are a good example of the advances made in construction
materials to meet changes in building safety and durability codes. Magnesium Oxide is available in many
forms, and for building construction purposes it is produced in various thicknesses and sheet sizes with various
grades, such as smooth finishes, rough textures and utility grades. It is white, beige or light gray in color.
