To make your builds as safe as possible for now and in the future, it’s essential to understand the role of Fire-Rated Sheathing. The sheathing is a panel used to form a surface on a building onto which other materials can be applied. When sheathing products are fire-resistant, they are engineered to withstand fire exposure and protect the building's structural integrity. The fire-resistant sheathing is most commonly used in 1-hour and 2-hour fire-resistance-rated assemblies for commercial and residential construction. The use of fire-resistant sheathing in wall assemblies helps protect the structure's integrity and contain and isolate a fire. Details vary by assembly, including the fire-resistance-rated wall thickness, which generally increases with exposure time. To provide increased fire protection, fire-resistant sheathing and other products are tested and evaluated by third parties. Here is the process:
Wall assemblies designed for fire resistance are tested in accordance with ASTM E119.
Materials are evaluated against the performance requirements of the International Building Code (IBC)
Fire resistance is evaluated by accredited agencies such as ICC-ES, Intertek, and UL.
Meet Code. Exceed Expectations with MagMatrix MgO Fire-Rated Structural Sheathing. As an evaluated component of 1-hour and 2-hour wall assemblies and roof deck applications, MagMatrix's panels combine flame-spread and burn-through resistance to bolster a building’s fire-resistance capabilities.
MagMatrix Fire Retardant MgO Sheathing is a patent-pending, code-compliant, fire-retardant MgO structural sheathing panel system that incorporates the extraordinarily flame and heat-resistant properties of magnesium oxide with the structural ability and overall utility of OSB and Plywood panels to create a uniquely high-performing, fire-resistance-rated structural sheathing product.
MagMatrix Multi-Support MgO fire-rated structural sheathing panel is different, and the resulting product is an extraordinarily high performing fire retardant MgO sheathing that offers a variety of assembly options not previously available with other fire retardant sheathings. MagMatrix protects against fire damage with a magnesium oxide panel that significantly reduces flame and smoke spread. Ideal for load-bearing building applications, MagMatrix Fire Retardant Structural Sheathing can be used in the same way as traditional OSB, but provides significant protection against fire damage and is a more environmentally friendly solution. It meets ASTM E84 and types III, IV, and V of the wood-frame construction requirements.
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 through alkaline-resistant glass fiber mesh reinforcement, giving our board unique high-performance structural properties. 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.

Why Choose MagMatrix Multi-Support Sulfate Magnesium Oxide Board
MagMatrix Multi-Support Magnesium Oxide Board is developed with MagMatrix Group with the most advanced technology of China, MgO sulfate chloride-free formula, and enhanced with four layers of high tensile glass fibers to achieve more strength, tensile, and more fire-resistance timing. It can provide 2 hours of fire resistance with a single layer of timber stud partition.
A2 Non-Combustible Board
These boards are well-suited for implementing various fire protection solutions. The boards are classified as A2 (non-combustible) under 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 standards. These properties make it highly effective, either as a stand-alone sheathing/underlayment or when laminated to other materials.
High Tensile and Impact Strength
It uses four layers of high-tensile fiberglass mesh, which gives our MagMatrix Multi-Support Sulfate MgO board model a bending strength of more than 16 MPa and an impact strength of more than 25 MPa. 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.
Breathable
Our MagMatrix Multi-Support Sulfate model of magnesium oxide boards is durable and fully breathable. The boards we recommend are highly resistant to moisture. It has the natural ability to absorb and release moisture, resulting in a heavier, more durable construction. It replaces 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, and no formaldehyde. 100% sustainable, 100% compostable, CO2-negative, vapor-permeable. And does not off-gas. It is ideal for people with chemical sensitivities.
Moisture/Water Resistant
MagMatrix Multi-Support Sulfate MgO Structural Panel is water-resistant and virtually impervious to water, with a maximum of 0,34% weight. Magnesia cement used in production is insoluble in water and prevents board delamination and swelling after long-term exposure to water. It retains its excellent dimensional stability, even in damp, humid conditions, because it is chloride-free and does not absorb water from the inside. 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 features 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 relatively low values of heat conductivity (0.0186 W/mK). and acoustic transmission (30 DB).
Dimensional Stability
This MagMatrix Multi-Support MgO fire-rated structural sheathing panel 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 with a sponge-like texture. Humidity does not fully fill its pores, leaving space for expansion when frozen. As a result, it does not change its internal structure when frozen. The 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
The MagMatrix Multi-Support board is easy to install and simple to cut, drill, shape, and fix. 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 is best suited to carbide tools, resulting in clean square cuts and higher-quality installations. Circular saws, including table saws, are most effective. 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 from the pile without marking the sheet below, resulting in faster, more accurate work.
The cuts are smooth and easy with conventional carbide-tipped circular saw blades, and ordinary bimetal jigsaw and multitool blades work fine for cutting around penetrations. The crew fastened the siding with pneumatic roof nailers; it can also be secured with high-quality screws (conventional black drywall screws sometimes snap off), framing nails, and siding nails. It is easier to cut than fiber cement because the dust is less 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, the MagMatrix Multi-Support board contains no hazardous components such as crystalline silica and hexavalent chromium, and the dust is not an irritant. In contrast, with 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 related to the extremely high energy consumption of cement manufacturing and the resulting air pollution, such as the release of dioxin, NOx, SO2, and particulates. In contrast, the production of Portland cement accounts for about 10% of global carbon dioxide emissions and is the world's most energy-intensive industry.
