We have two formulas for this model. One is the magnesium sulfate oxide which is totally chlorine-free and we can issue the Intertek test report for clients and the market. Another one is the chlorine magnesium sulfate oxide formula which we control strictly the chlorine content below 1.5% level. All the bending strength is 18Mpa. 

MagMatrix Multi-Support Sulfate MgO Board is a more environmentally-friendly material than some other more traditional building materials.  The production of MgO is energy efficient and produces few greenhouse gases.  This is a potential factor in the increasing popularity of the material. It is slightly absorptive, meaning that it is possible to paint and bond to the surface.


MagMatrix Multi-Support fire-resistant wallboard is a high-performance and non-combustible sulfate MgO board. And also this magnesium oxide board also can be called for Magnesium glass fiber gypsum board in brief as MgSO4 Panels. It is superior to any traditional concrete, drywall, gypsum board in the market. It feathers high-impact that is very suitable for exterior & interior & ceilings & SIPs & modular Wall panels constructions. It obviously improves & enhances its fire resistance, acoustic and thermal insulation performance and enjoys high impact strength to give more durability, more resistance to moisture, mold, and mildew. Also, our panels can be painted, render on-site or off-site to provide more beautiful surface conditions.

Manufacture Process

MagMatrix Multi-Support board model is manufactured with high-end magnesium oxide powder taking more than 70% content with inorganic substances and alkaline resistant high tensile fiberglass meshes. The MgO board is naturally cured using no energy through cold fusion. It is inorganic and has no toxic inputs. It contains no formaldehyde, fly ash or crystalline silica – ingredients/inputs found in plywood, OSB, fiber cement and gypsum-based building materials. It achieves superior strength and flexibility with the input of alkaline resistant glass fibers meshes which supports our board get a unique high-performance structural property. Our MgO board undergoes a low energy manufacturing process, as much as 50% less than competing building products and actually absorbs carbon dioxide from the atmosphere during its exothermic curing process.

A2 Non-Combustible Board 

These boards are especially predestined for the implementation of various types of fire protection solutions. The boards are classified as A2 (non-combustible) boards pursuant to European Standard EN 13501-1. Also, when it comes to providing a definition for non-combustibility we need look no further than the Building Regulations which defines it as: "Any product classified as non-combustible when tested in accordance with the requirements of BS476: Part 4: 1970 - Fire tests on building materials and structures - Non-combustibility test for materials, or: "Any product classified as Class A2 in accordance with BS EN 13501-1:2002 - Fire classification of construction products and building elements. Classification using data from reaction to fire tests when tested to BS EN ISO 1182:2002 Reaction to fire tests for building products - Non-combustibility test and BS EN ISO 1716:2002 Reaction to fire tests for building products-Determination of the gross calorific value." Magnesium oxide boards are essentially noncombustible, with a flame spread of ZERO and a smoke development of ZERO, as measured by ASTM & EN standard. These properties make it highly effective either standing alone as a sheathing/underlayment or when laminated to other materials.

High Tensile and Impact Strength

It uses 4 layers of high tensile fiberglass meshes, which gives our MagMatrix Multi-Support Sulfate MgO board model bending strength more than 16Mpa and the impact strength more than 25Mpa. This maintains a good racking strength on the board application. It provides a more durable wall construction material compared to traditional drywall to help prevent surface scuffs and abrasions as well as deeper indentations that require frequent cosmetic repair. 


Our MagMatrix Multi-Support Sulfate model of magnesium oxide boards is durable and fully breathable. The boards we recommend handle exposure to moisture extremely well. It has the natural ability to get in and out moisture, giving a heavier and more durable construction building. It takes the place of oriented strand board (OSB), plywood and gypsum sheetrock for all sheathing, wallboard, subfloor, and roof decking applications.

Non-formaldehyde and Non-Toxics

MagMatrix Multi-Support MgO board contains no nasty chemicals, no gypsum, no cement-based content, no formaldehyde. 100% sustainable, 100% compostable, Co2 negative, vapor permeable. And does, not off-gas. It is ideal for chemically sensitive people.


MagMatrix Multi-Support Sulfate MgO Structural Panel is water-resistant and virtually impervious to water, not more than 0,34% weight Magnesia cement used for the production is insoluble in water and prevents delamination of the board as well as swelling after long-term exposure to water. lt retains its excellent dimensional stability, even in damp and humid conditions because it is chloride-free and will have no water happening from its' inner side. It can be applied at an early stage of the construction program, even before the building is weathertight. It is suitable for semi-exposed applications and can be left undecorated.

Acoustic Performance

MagMatrix Multi-Support MgO Board is characterized by excellent acoustic and thermal insulation. It can be successfully used in combination with modern insulation materials (insulant, construction membrane) for exterior decoration of the building at quite low values of heat conductivity (0.0186 W/mK)) and acoustic transmission (30 DB).

Dimensional Stability

This MagMatrix Multi-Support Sulfate  Magnesium Oxide board has excellent dimensional stability under heat and in severe moisture environments. It also has a small expansion rate. Boards are suitable for most industrial applications due to good impact resistance. Our board is a porous material of a sponge-like texture. Humidity does not fill completely in its pores leaving some space for expansion when being frozen. Due to this, it does not change its inner structure when being frozen. Dimensional stability of the MgO board is 50 cycles in freeze/thaw and the loss of mechanical strength is only 0.5% (at the allowable of 18%).

Efficient Cutting & Fastening Method

MagMatrix Multi-Support board is easy to install, it is simple to cut, drill, shape and fixed. It can be worked in the same way as timber products with no special tools required, and it is also maintenance-friendly. Our Multi-Support SS model of MgO board will work best with carbide tools, resulting in clean square cuts that will provide higher-quality installations. Circular saws including table saws work best. The boards can be scored and snapped using disposable knives that can cut through the fiberglass mesh from the smooth side. Edges can be routed flush or to create shapes and patterns using carbide cutters. When using saws like the hand electric saw with precision depth adjustment, sheets can be cut directly off the pile without marking the sheet below, which contributes to fast and accurate work.


The cuts are smooth and easy with conventional carbide-tipped circular saw blades and that ordinary bimetal jigsaw and multi­tool blades work fine for cutting around penetrations. And the crew fastened the siding with pneumatic roof nailers, and, it can also be fastened with high-quality screws (conventional black drywall screws sometimes snap off), framing nails, and siding nails. It is better than fiber cement to cut because the dust wasn’t as irritating and the composition is easier on cutting tools. But as with cutting any materials that make dust, all workers should be protected from the dust by using a vacuum, blowers, breeze, or dust masks.​

Environmental Friendly & Green Building Board

Unlike Portland Cement-based boards and pours, MagMatrix Multi-Support board contains no hazardous components such as crystalline silica and hexavalent chromium, and the dust is not an irritant. In contrast cases of extreme exposure to Portland-based products, the results can lead to adverse health outcomes and worse. Unlike Portland cement-based boards, there are no environmental concerns from extremely high energy consumption in manufacturing cement, and the related air pollution, such as the release of dioxin, NOx, SO2, and particulates. In contrast, the production of Portland cement contributes to about 10 % of world carbon dioxide emissions and is the most energy-intensive industry in the world.
