Sulfycor manufacture magnesium oxide board (magnesium sulfate board) has been design to replace plywood, oriented strand board, fiber cement and gypsum based sheet building products. It offers superior structural and high-impact strength, stiffness, durability and fire-resistance.
FIREPROOF
Magnesium oxide board (Mgo Board) is a sustainable, non-flammable option for commercial and residential construction. It can resist fire for up to 2-3 hours, staying unburned at 800ºC and Passed grade A1 fire rated testing.
WATER RESISTANT
Sulfycor maintains its structural integrity even when slightly bent and remains stable when exposed to moisture, preventing warping, swelling, or delamination.
HEALTH SAFE
Our magnesium oxide boards are free from fly ash, formaldehyde, crystalline silica, and other toxins, making them a safe option for construction.
TERMITE PROOF
Sulfycor’s natural resistance to moisture, fire, mold, and pests prevents warping, swelling, or deterioration, making it a durable choice for construction.
ENVIRONMENTAL-FRIENDLY
From natural compounds, our boards are landfill- and recycle-safe, deemed ‘nutritional waste.’ They undergo 36-month freeze/thaw testing, enabling year-round construction.
FUNGUS RESISTANT
With antimicrobial characteristics, Sulfycor resists mold, mildew, fungi, and rot. Free of chloride elements, it solves issues of light corrosion and expansion.
Premium Magnesium Oxide Board Size
(100% chlorine-free mgo board/magnesium sulfate board)
High quality chlorine-free magnesium oxide boards, also known as magnesium sulfate boards, are the top choice for a multitude of construction purposes such as wall and ceiling installations, subflooring, interior decoration, and sheathing.
Our MgO panels are available in the standard size of 4 ft × 8 ft, with a thickness variety from 5mm to 20mm, guaranteeing a tailored solution for every project.
