MagMatrix Economic® Magnesium Oxide FirePro Structural Subfloor 

A1 Non-combustible | Fire Resistant | Strong Bending Strength | Impact Resistance |Screw Directly | Dry Quickly Installation | 20% Lighter than Portland Cement Board | 100% Asbestos and Silica Free

MagMatrix Economic® Magnesium Oxide FirePro Subfloor Board gives high performance in bending strength, and fire ratings with China the most advanced MgSO4 chloride-free sulfate technology. It is lightweight and high strength. The Non-combustible floorboard is resistant to fire, water, mildew, insulate to sound and heat. It offers a superior and price competitive, environmentally friendly alternative to subfloor board from fiber cement board or subfloor plywood,  OSB subfloor and chipboard subflooring products. 


MagMatrix Economic® MgO fire-rated subflooring board is with square edges for substrate floor applications. It could be internal & external. It is with a neat secure surface. It could be designed primarily as a substrate for most finishes such as tiles, vinyl, carpet or timber. It could also suitable as a finished surface with itself. 

Fire Resistant

MagMatrix Economic® Magnesium Cement FirePro Subflooring is a glass-fiber-reinforced concrete board that can be combined with other non-combustible materials to set up fire-rated floor assemblies. It is A1 non-combustible and zero flame spread and smoke development index. 

Quick Installation & Cutting

MagMatrix Economic® FirePro Subflooring when making installation, it could be super fastener withdraw power to hold nails and screws like plywood. The dimension is stable, the panels will not buckle or warp like wood sheathing. It installs just like wood sheathing, a circular saw for cutting, screws for fastening. It meets ASTM E136-12 for use in all types of noncombustible construction. 

Description in Subfloor

MagMatrix Economic® FirePro Structural Subfloor Board 18mm (3/4") can carry a total load, alive and dead, of 320 psf (15.3 kPa) when cold-formed steel framing is spaced 24" (610mm) O.C.

It is mechanically fastened to cold-formed steel joints, timber frame trusses or framing members. A noncombustible ceiling assembly is attached to the bottom of the floor joists to complete the construction. This floor system is designed to carry gravity and lateral loads. The surface of the boards shall be covered with tile or carpet. MagMatrix Economic® structural subfloor panels can also be installed on wood joints and hot-rolled steel framing modular construction systems. 

It has a maximum linear variation with a change in the moisture content of less than 0.1% in accordance with ASTM C1186 testing (from 50% to 90% relative humidity). This means that the panels will not buckle or warp like wood sheathing.
