MgS Wallboard

A high-performance lining and sheathing board for modern construction.

Overview

SULFROCK’s Magnesium Sulphate Wallboard (MgS Wall Board) is a next-generation building panel engineered for exceptional strength, fire resistance and long-term stability. Manufactured using a chloride-free magnesium sulphate composition with reinforced binders and stabilising additives, the board delivers reliable performance across a wide range of construction environments.

Through a controlled compression and curing process, MgS Wall Board achieves excellent density and structural integrity. Its non-combustible mineral composition provides enhanced safety and peace of mind for building designers and installers.
