Magnedure Flooring Board
Description

Magnedure™ is a non-combustible composite cementitious material which may be used as an alternative to fibre cement boards, and incorporated into Sounddown's interior flooring assemblies. The boards are embedded with layers of high tensile glass fibre mesh which makes them light yet with a high bending structural strength.

Magnedure is a next-generation MgO board using a sulphate-based binder, offering high strength, stability, non-combustibility, and resistance to biological degradation. Developed using DuPont research, Magnedure eliminates the corrosion risks of older MgO boards while delivering superior performance and reliability.

Available in panels 2700mm x 600mm and 19mm thick, Magnedure is supplied by Build Anatomy for use in interior flooring assemblies, and are not intended to be left exposed.
