Magnesium Oxide Board -- Fire Rated Structural Building Board

Fire Rating Performance

Fire Rating Performance:Perseverance Model is ASTM E136 Noncombustible tested & certified fire rated structural building panel. It is made from CHINA the most advanced BMS formulation for the Magnesium Oxide Board which could achieves 120 minutes of fire resistance with a single 12mm layer of board on either side of a steel stud partition and walls with ASTM E119.

Concept 

Perseverance model Sulfate MgO Board is a medium density magnesium oxide board that is embedded with 4 layers high tensile glass fiber meshes layers to make the supreme strengthening power. Perseverance MgO Board is EN13501-1 A1 & ASTM E136 non-combustible, which has a low environmental impact and provides a very stable substrate to combine with various surface finishes for the construction industry where have the fire-resistant request.

​

It is a non-combustible sheathing panel for steel-frame applications and off-site manufacturing construction methods and helps provide a solution where cost-effective structural fire-resistant panels are required. As well as providing A1 Fire Performance to EN-13501-1& ASTM E136 noncombustible tested & certified. It offers excellent impact resistance and convenient score-and-snap workability.

​

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 & enhance 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

Perseverance MgO fire rated structural wallboard 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 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 fiber meshes which supports our board get a unique high-performance structural property. Our 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 Perseverance Magnesium Board for Your External & Internal Fire Rated and Sturactural Board Applications?

Perseverance model MgO is developed with the most advanced technology of China MgO sulfate chloride-free formula and enhanced with 4 layers high tensile glass fibers to achieve more strength tensile and more fire-resistance timing. It can achieve 2 hours of fire resistance with a single layer with a steel stud partition structure.

A1 & ASTM E136 Non-Combustible Building Board

These boards are especially predestined for the implementation of various types of fire protection solutions. The boards are classified as A1 (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 A11 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."

​

ASTM E136 noncombustible test and certified. ASTM E136 noncombustibility tested with the Standard Test Method for Assessing Combustibility of Materials Using a Vertical Tube Furnace at 750℃, as defined in 2012, 2015, and 2018 IBC model codes.

High Tensile and Impact Strength

It uses 4 layers high tensile fiberglass meshes, which gives our  Multi-Support SS MgO board model bending strength more than 22Mpa and the impact strength more than 38Mpa. 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 Perseverance sulfate magnesium oxide boards are 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

Perseverance Fire Rated Building 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.

Moisture/Water Resistant

Perseverance fire-rated structural building board 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 due to it is chloride-free and will have no water happens 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

It 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

The 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 MgO 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

Perseverance fire-rated structural panel 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. Multi-Support SS model of the 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.
