MagMatrix Premier® Fire Rated Structural Subflooring Board


MagMatrix Premier® Fire Resistant Subfloor Board gives high performance in bending strength, and fire ratings with China the most advanced BMSC (Basic Magnesium Sulfate Cementitous) chloride-free MgO technology. It is lightweight and high strength. The Premier® fire-rated structural subfloor panel is resistant to fire, water, and mildew, and insulates to sound and heat. It offers a superior and price-competitive, environmentally friendly alternative to fiber cement and plasterboard products. The subflooring panel also gives a unique engineered cementitious composite flooring sheet suitable for both interior and exterior flooring applications. It has a tongue & groove joint down each long side for a flush tight fit.

MagMatrix Premier® Fire Rated Structural Subfloor Panel is a high-strength, reinforced magnesium-based mineral cementitious panel for use on either a timber or steel frame that can be used to deliver Fire Resistance Level (FRL) 60 - 120 minutes in the down direction. This, in conjunction with its exceptional acoustic performance, makes the structural subfloor panel ideally suited for multi-level lightweight construction. Lighter than precast or poured concrete, MagMatrix Structural Panels install like wood sheathing and are mold-, moisture- and termite-resistant. Providing a faster, easier, and more efficient way to build floors. It is a lightweight yet incredibly strong multi-purpose flooring material for all forms of lightweight construction. It begins as a cost-effective substrate flooring for all applications such as bathrooms, living areas, or external decks. 


MagMatrix Premier® fire-rated flooring board is with Tongue & Groove (T&G) edges for substrate floor application. It could be internal & or 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 be suitable as a finished surface itself. 


MagMatrix Premier® Fire Resistant Subfloor BoardFlooring Board has opened the excellent quality of Tongue & Groove edge which could offer an extensive range of floor options and solutions. This Premier® Subfloor Boarding system can be used in a variety of applications, whether it is a new building e.g. offices, shops, transportable, kit homes, or additions and renovations to an existing building. It is ideal for: sub-floors; suspended floors and areas where moisture resistance is necessary. It is also an excellent product to receive a wide variety of floor coverings. 

No special tools are required to fix the panel, which can be cut like any other fiber cement sheet and does not need to be pre-drilled before fixing. Yet at only 16mm or 19mm thick it outperforms any other comparable product in strength. 

Size & Weight

Light Weight

MagMatrix Premier® FirePro Flooring Board is lightweight and easy to handle on the construction site. We can control the density of 1400kg per cubic meter. The bending strength could be 25Mpa in dry conditions and 20Mpa in wet conditions. 

Non-Combustible & 90/90/90 &120/120/120 Minutes Fire Resistant Levels

MagMatrix Premier® Sub-Floor Board is an EN13501-1 A1 non-combustible and could be applied in conjunction with floor systems to get FRL 90/90/90 and FRL 120/120/120 with relatively Fire Resistant Levels regulates. 

Chloride Free

MagMatrix Premier® Substrate Flooring Board is with China's most advanced MgSO4 formula which is totally chlorine-free and has no corrosive for all kinds of metals. The chloride content is 0.018-0.065% which is tested with Intertek Report available for our customers who have interested in this content to check. 


The board offers remarkable acoustic insulation performance. The flooring system for Class 2 or 3 Type-A construction on timber or steel frame offers an Rw/Rw+Ctr of 62/58 (BCA for Rw +Ctr is >50. If offers the most excellent acoustic insulation performance and no one could beat it. 

Environmental Friendly Materials

It is an advanced high tensile strength, and low carbon glass fibers mesh reinforced oxysulphate cementitious board that is embedded with 4 layers high tensile glass fibers which could achieve the bending strength of 25Mpa in the dry condition and 20Mpa at the wet condition. It does not contain asbestos and is toxin-free. It is completely free of harmful toxins and particles such as heavy metals and asbestos. 

Low Carbon 

It is a low carbon product which contains about 35% of the embodied energy of equivalent portland cement derived materials. 

25 Years Durability

The Board is long-term durable and is warranted for more than 20 years. We are improving to 50 years of the life of service. In the "Soak Dry" test, we are achieving 50 cycles test and we will publish our new and more advanced 50 years sub-flooring MgO sulfate formula soon for the market. 

Mould & Termite Resistance

The Premier® Subflooring Board is resistant to mold and termite attacks that is reliable, safe, and effective. With our increasingly popular mold-resistant board range, you no longer need to suffer the consequences of mold and seriously health-affecting bacteria in your home or working environment. 

Superior Finishes

The Board provides a polished concrete-like surface suitable as a quality finish in itself. The superior smooth surface allows for finishing with paint, wallpaper or texture directly onto it. 

Mechanical Properties


  •  The fire-rated structural subflooring panel can be cut and worked just like comparable fiber cement sheets but offers improved bending strength characteristics and finish quality. 

  • The fire-rated structural subfloor panel meets the ASTM E84 building code and can be used in conjunction with floor systems to achieve FRL 60/60/60, 90/90/90, 120/120/120 in the down direction and up to BAL-FZ bushfire compliance. 

  • The fire-rated structrual subfloor panel is an advanced high strength, low carbon magnesium oxide panel with about 40% lower CO2 emissions during the production process than the traditional fiber cement panel. It is toxin-free and is 100% recyclable. 

  • The structural subflooring panel is a high-strength yet lightweight product weighing as little as 35.5kg per sheet. Our 16mm is comparable in strength to the other fiber cement sheets at 19mm and 20mm thickness. >

  • The panel is long-term durable and is warranted for 20 years. It is with 25 cycles "Soak Dry" and performs a mean Mpa of >20. 

  • The subfloor panel provides a polished concrete-like surface suitable as a quality finish in itself. Class 2 Concrete finish suitable for clear sealing available on request. 

  • The panel is asbestos-free and resistant to mould and termite attack.
