MagMatrix Multi-Support Magnesium Oxide Fire Rated Structural Subflooring
ASTM E84 Zero Flammable & Smoking | Fire Resistant | Strong Bending Strength | Impact Resistance |Screw Directly | Dry Quickly Installation | 20% Lighter than Portland Cement Board | 100% Asbestos and Silica Free | ICC & IBC Building Code Type III IV V Applications
Concept
MagMatrix multi-support magnesium oxide fire-rated structural subflooring panel gives high performance in bending strength, and fire ratings with the MGO cement industry's most advanced BMSC 517 chloride-free MgO formulation technology. It is lightweight and highly durable. The fire-rated structure is resistant to fire, water, and mildew, insulating against sound and heat. It offers a superior, price-competitive, environmentally friendly alternative to subfloor boards, including fiber cement boards, subfloor plywood, OSB subfloor, and chipboard subflooring products.
Fire Resistant
MagMatrix multi-support magnesium cementitious fire-rated subflooring is a glass-fiber-reinforced concrete board that can be combined with other non-combustible materials to set up fire-rated floor assemblies. It is a zero flame-spread and smoke-development index.
Quick Installation & Cutting
MagMatrix multi-support subflooring panel, during installation, can be used as a super-fastener to withdraw power to hold nails and screws, like plywood. The dimension is stable, and the panels will not buckle or warp as wood sheathing does. It installs just like wood sheathing, a circular saw for cutting, and screws for fastening.
Description in Subfloor
MagMatrix multi-support fire-rated structural subfloor board 19mm (3/4") can carry a total load, alive and dead, of 320 psf (15.3 kPa) when timber framing is spaced 24" (610mm) O.C. It is fire-resistant, high-density, structurally. When used as a subfloor, MagMatrix FirePro Structural Subfloor Panel can replace plywood and OSB subflooring in certain instances and eliminate the need for gypsum underlayment.
It has a maximum linear variation of less than 0.1% in moisture content, in accordance with ASTM C1186 testing (from 50% to 90% relative humidity). This means the panels will not buckle or warp as wood sheathing does. Do not gap MagMatrix Structural Panel, Concrete Subfloor, and roof panels.
Cutting the concrete subfloor and roof panel requires a carbide-tipped saw blade and a circular saw equipped with dust collection or adequate ventilation to control airborne dust. Wear safety glasses, gloves, and NIOSH-approved dust masks during the cutting operation. Use a stand-up screw gun and self-drilling No. 8-gauge screws when fastening the panel.
Limitation
MagMatrix structural subfloor always requires a finished floor covering such as ceramic tile, vinyl, wood, carpet, or other approved materials. Without an underlayment, future removal of these floor coverings may damage the structural subfloor. The only floor coverings that do not require an underlayment are residential carpets and pads.
Installation
MagMatrix structural subfloor must be installed in accordance with the Guide, using only the listed materials and components. For all types of construction, appropriate safety procedures must be followed to protect installers from personal injuries, including lifting incorrectly. and falling, and from eye, hand, and action caused by dust. Always orient panels perpendicular to the joists; when the joists change direction, so does the panel. Install panels in a running bond pattern so that end joints fall over the center of the framing members and are staggered.
Fasten each panel after placement, in accordance with the fastening schedule in the contract documents. Use adhesive at both tongue-and-groove and square edges. Use only non-combustible polyurethane-based adhesive. Ensure panels are tight with the adhesive applied prior to screw attaching the panels to the steel framing.
For all panels less than 24" (610mm) wide, all edges must be supported by blocking. Blocking must be cold-formed from steel complying with the relevant standard, with a minimum base metal thickness of 54 mils (0.0538 inches or 1.37mm) (No. 16 gauge) and a minimum G60 galvanized coating.

Product Data
Sizes and Packaging: 18mm/19mm/20mm × 1200mm × 2440mm panels. Each panel weighs approximately 58kg and 63kg (35 sheets per pallet) and is intended to be handled by two people in the upright position.
Maintenance: MagMatrix Structural Subflooring requires no routine maintenance other than removing standing water and repairing damage caused by abuse. Any cracked or broken panels should be replaced with the same MagMatrix Structural Panel and secured in accordance with the fastening schedule prescribed in the original installation documents. The replacement panels must be a minimum of 24" (610mm) wide and must span a minimum of two supports. If not, the replacement panel must be fully blocked on all sides.
