Magnesium oxychloride cement board is a green, affordable alternative to gypsum, fibre-cement and OSB that is sustainable, strong and durable, and safe. It has a very low embedded energy to produce, is highly fire and moisture resistant, structurally similar to OSB, and easy to work with using standard tools. Magnesium oxychloride cement board does not emit VOCs, asbestos, or other toxins, and actively prevents mold and mildew growth. Contractors who have used it praise its ease of installation, rainscreen performance, and ability to be primed and painted the same day.

1. The Green, Affordable Alternative
to Gypsum, Fibre-cement & OSB –
Magnesium Oxychloride Cement Board
Sustainable
• Very low embedded energy, magnesite (magnesium carbonate) calcines at 1/3 the temperature
of limestone (calcium carbonate) and cures exothermically, unlike gypsum which uses 1% of all
North American energy for kiln drying
• When made locally, MagO will be neutral to negative. Currently made in China,
it has a low carbon footprint mainly due to shipping
• Fully useable life cycle, either by reusing, recycling or repurposing as a fertilizer additive
Strong, Durable & Versatile
• Highly fire-resistant: UL W490, 12mm board provided 1 hour separation
• Impervious to wetting: does not change shape, size or lose strength when wet
• Structural: similar in strength to OSB. One screw into 12mm board can hold over 200 lbs
in shear, no plugs, backing or toggle bolts
• Highly impact-resistant: suitable for areas subjected to impact and abrasion
• Easy to work with: uses standard carbide tools, wallboard applications can be
installed and painted the same day. No corner bead required
Safe & Non-Toxic
• No VOC, no asbestos, formaldehyde or out-gassing, no carcinogens
• Actively anti-microbial, magnesium chloride content prevents mold and mildew
• Fully tested for use in Canada and US
“We are installing Mago on one of our projects and are absolutely loving it -
from ease of install, the rainscreen aspect and priming and painting.
Our team highly recommends it!”
– Chantalle Elliot, Infinity Pacific Homes
“We tested it and were amazed. I took a few slapshots at it with a real puck and
it barely dented … I’m convinced the product would be great in all of our garages
and in many other areas of the homes we are building.”
– Cam Kraychy, Rocky Point Homes
