Magnesium Oxide (MgSO4) board is a highly versatile, non-combustible building material widely used as a superior alternative to drywall, plywood, and cement board. Thanks to its resistance to fire, moisture, mold, and pests, it is primarily applied in fire-rated walls & airducts, wall sheathing, subflooring/underlayment and modular houses.
MgO Board Applications
Mgo board widely use for wall sheathing, subfloor/underlayment, modular houses and sip (structural insulated panel)
Exterior & Interior Wall Sheathing
MGO boards feature non-combustible, moisture-proof and anti-deformation properties, delivering stable protection for wall substrates. (Thickness: 6~15mm)
Subflooring & Underlayment
Offer high structural strength and mold resistance, with stable load-bearing performance and reliable moisture isolation. (Thickness: 16-22mm)
Wall Decorative Panel
Rated A2 fire-resistant, these decorative boards support fast installation and are fully compatible with all indoor finishing materials. (Thickness: 2-12mm)
Structural Insulated Panel
With A2 fireproof performance, the boards enhance building safety and thermal insulation for SIP assembly systems. (Thickness: 8-12mm)
MgO Board for Modular House
These lightweight A2 fireproof and moisture-proof panels allow rapid assembly and form robust prefabricated building units.
MgO Boards for Fireproof Ductworks
Non-combustible MGO sheets withstand high temperatures and inhibit flame spread, ideal for HVAC ventilation system applications.
MgO Board Key Advantages
FIRE SAFETY
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 not catching flame until 1200ºC.
Moisture 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.
