MagMatrix MagFirePro Sheathing Board

About MagFirePro Sheathing Board Concept

MagMatrix MagFirePro Sheathing Board is the most innovative sheathing board mainly applied for the steel frame modular construction industry that is feathered with Euroclass A1 Non-combustible and fire-rated sheathing board. It helps provide a cost-effective structural panel, too.  As well as provides A1 Fire Performance to EN13501-1, it also offers excellent impact resistance and convenient score -and-snap workability.  

MagMatrix MagFirePro Sheathing building board, for applications that require a slightly lighter board with improved fire properties. The product offers very similar properties to the cement particle board, however, due to the magnesium oxide formula, it offers greater fire resistance. Fully tested to achieve a one to two hours through wall solution with external sheathing board properties.

As a sheathing board, it can be used behind rain screen cladding, insulated facades and cedar cladding (in this application, the use of a water-resistant/ breathable membrane such as Tyvek, on to the face of the board, is recommended in line with good building practices for external cladding). CE marked and conforms to BS EN 12467.

Manufacture Process

MagMatrix MagFirePro Sheathing Board is manufactured using inorganic substances and high tensile premium fiberglass meshes to gain an excellent impact and bending strength. It is making the first and second and third times curing technology at moisture conditions. That is very energy savings. That is unlike similar competitive products on the market which use autoclaving c technology. This gives MagMatrix MagSF Fire Resistant Board an extremely low impact on the environment. MagMatrix MagSF Sheathing Board achieves its superior strength and flexibility by the introduction of 4 layers of high tensile glass fiber meshes. Consistent high quality of the product is maintained and monitored through an advanced digitally controlled process to ensure a superior finished board for our clients' application.  

Features and Benefits

MagMatrix MagFirePro High-Performance Exterior Sheathing board is a superior water-resistant that allows for water vapor permeance. Excellent fire resistance properties, and numerous fire-rated assemblies. Mold and moisture resistance. Compatibility with most exterior wall systems and applications. Conformity to design and code requirements. Strength - with enough flexibility to bend to curved surfaces. A lightweight sheathing that cuts like regular gypsum board and is easy to handle and install - with minimal skin irritation due to fully-embedded glass mat. MagMatrix MagSF Sheathing is the next generation of the industry standard for high-performance, weather-resistive, the alternative to the gypsum-based sheathing. 

MagMatrix MagFirePro Sheathing Board has been designed and engineered to outperform traditional wood, gypsum, and fiber cement sheathing panels, not only from a structural standpoint but also in terms of speed of installation on-site, which in turn translates into bottom-line savings.

MagMatrix MagFirePro Sheathing Panel is a code-compliant Class A1 fire rated sheathing product and provides unparalleled resistance, not only to fire, but also water, mold and wood-boring insects. Essentially, one product that combines all of the benefits of plywood or OSB from a structural standpoint, exterior gypsum from a fire-resistance standpoint and fiber cement from a water resistance standpoint.

MagMatrix MagFirePro sheathing installs with standard tools, methods, and fasteners and can be nailed or screwed directly to steel framing. Lap siding or cladding systems can be fastened directly to our panel, due to its superior fastener withdrawal capacity, which in turn reduces the risk associated with fasteners missing a stud.
