The fire-rated MOS board specifiers actually trust.
Magply is an A1 non-combustible MOS board designed for fire mitigation and high-performance sheathing applications. Manufactured using a magnesium oxysulfate formulation, Magply is engineered to provide improved stability and durability compared to traditional magnesium oxide boards.
As an A1 non-combustible board, Magply is suitable for use across timber frame and steel frame construction, modular and offsite build, rainscreen cladding, render systems, roofing systems, spandrel panels, SIP panels and pattressing. Its low chloride content supports long-term performance within wall, ceiling, roof & façade build-ups.
Magply has been tested in a wide range of fire-rated assemblies and achieves a Euroclass A1 reaction to fire classification. It is intended to be used as part of a designed system, fixed to suitable framing and covered by appropriate finishes in line with the overall construction requirements.
