The patent covers the incorporation of an antimicrobial additive package into the wallboard to resist the growth of mould and mildew.  The patented wallboard employs a two-part antimicrobial system and an innovative targeting approach to provide protection against mould, mildew and fungus.

Microban specialises in built-in antimicrobial product protection. It has secured a European patent relating to treated wallboard. It already has wallboard technology patents in other parts of the world, including North America, China, Hong Kong, Australia and Brazil.

“In wall board, fungal issues typically occur at the interface between the paper and the gypsum core,” said Dr Ivan Ong, vice president for research & development. “Fungal infiltration of this nature can occur without visual cues until it becomes extensive and damaging. The patent provides an effective and manufacturing-friendly method to deliver a combinatorial package of antimicrobial agents to specifically target microbial issues this interface.”
