MgSO₄ BENEFITS

Our magnesium sulphate boards (chlorine-free) are engineered to deliver exceptional fire resistance, moisture stability, and long-term durability. Suitable for residential, commercial, and industrial projects alike, MgS boards provide a reliable, sustainable, and high-performance solution for modern construction.

NON-COMBUSTIBLE

Magnesium sulphate board (MgS board) is a sustainable, non-flammable option for residential, commercial, and industrial construction. It resists fire for up to 2–3 hours, remains stable at 800°C, and will not ignite until around 1200°C.

WATER RESISTANT

SULFROCK MgS boards maintain their structural integrity even under moisture exposure. They resist warping, swelling, and delamination, ensuring long-term stability in humid or wet environments.

HEALTHY BY DESIGN

Our magnesium sulphate boards are free from fly ash, formaldehyde, crystalline silica, and other harmful substances – providing a cleaner, safer choice for modern construction.

TERMITE PROOF

SULFROCK’s moisture-stable, fire-safe and inorganic composition naturally prevents damage from pests, mould, and decay, delivering long-lasting durability in all climates.

ENVIRONMENTALLY FRIENDLY

Made from natural compounds, our boards are recyclable and landfill-safe, classified as “nutritional waste.” They also pass 36-month freeze / thaw testing, ensuring reliable year-round performance.

FUNGUS RESISTANT

With built-in antimicrobial properties, SULFROCK MgS boards resist mould, mildew, fungi, and rot. The chloride-free formulation eliminates risks of corrosion and material expansion.
