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 China the most advanced BMSC chloride-free MgO formulation technology. It is lightweight and of high strength. The fire-rated structure is resistant to fire, water, and mildew, insulating to sound and heat. It offers a superior and price-competitive, environmentally friendly alternative to subfloor boards from fiber cement boards or subfloor plywood,  OSB subfloor, and chipboard subflooring products. 

 

MagMatrix multi-support MgO fire-rated subflooring board is with square edges for substrate floor applications. It could be internal & or external. It is with a neat secure surface. It could be designed primarily as a substrate for most finishes such as tiles, vinyl, carpet, or timber. It could also be suitable as a finished surface with itself. 

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 zeroed flame spread and smoke development index. 

Quick Installation & Cutting

MagMatrix multi-support subflooring panel when making installation could be a super fastener to withdraw power to hold nails and screws like plywood. The dimension is stable, the panels will not buckle or warp like wood sheathing. 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 can remove the need for gypsum underlayment. 

It has a maximum linear variation with a change in the moisture content of less than 0.1% in accordance with ASTM C1186 testing (from 50% to 90% relative humidity). This means that the panels will not buckle or warp like wood sheathing. 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 according to 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 from lifting incorrectly, falling, and eye, hand, and lung irritation from 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 it has been placed following the fastening schedule listed in the contract documents. Use adhesive at both tongue & 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 of 54 mils (0.0538 inches or 1.37mm) base metal thickness (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 does not require any regular maintenance except to remove standing water and repair damage from abuse. Any cracked or broken panels should be replaced with the same MagMatrix Structural Panel that is secured following 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.
