While Calcium Silicate raised floor panels have historically served as a dense non-combustible option, Steel-Encapsulated Magnesium Oxide (MgO) raised floor panels represent a superior engineering upgrade—delivering higher impact resistance, lower dead-load weight, superior screw-holding strength, and zero silica dust hazard.

Architects and specification teams often combine Terracotta Rainscreens with High-Density Fiber Cement Panels across elevations to create dynamic depth, or choose between them based on weight budgets and design intent:

A Magnesium Oxide (MgO) duct board is a factory-prefabricated, non-combustible structural panel engineered specifically for central air conditioning supply ducts, commercial ventilation, and passive fire/smoke extraction systems. Manufactured from magnesium sulfate/oxide chemistry, MgO duct board combines structural rigidity, inherent thermal protection, and Class A1 fire resistance in a thin 6mm to 10mm profile, eliminating the labor-intensive external insulation required by traditional galvanized sheet metal.

Technical Comparison: MgO Board vs. Fiber Cement Board vs. Galvanized Steel in HVAC Duct ...

Traditional steel ducts come with a massive list of headaches: high weight, complex on-site fabrication, and the added cost and labor of installing external thermal insulation. MgO boards change the game completely:

• 🔥 Class A1 Fireproof Safety: Certified non-combustible material that provides ultimate protection for central air supply and critical fire smoke extraction systems.

• 🌡️ Built-in Thermal Insulation: Unlike bare steel that bleeds energy, MgO boards have natural insulating properties—saving you time, material, and ...

When designing for extreme fire loads and safety compliance, fiber cement boards outperform traditional materials across several key metrics:

150mm fiber cement weatherboard (such as standard 150mm width cladding planks) is a popular choice for exterior wall cladding in modern residential and commercial builds.

Key Dimensions & Technical Specifications

Total Width: 150 mm

Effective Coverage Width: ~120 mm to 130 mm (due to overlap during installation)

Standard Thickness: Typically range from 16mm (thick-profile planks for deep shadow lines, such as James Hardie Linea™) to 8mm – 10mm (standard lap planks).

Standard Lengths: 3.6m to ...

180mm Fiber Cement Weatherboards (also referred to as fiber cement cladding or lap siding) are a low-maintenance, weather-resistant exterior cladding option designed to mimic natural timber planks.

Key Specifications

Fiber cement weatherboards designed with deep shadow lines are one of the most popular cladding choices in modern architectural design.

Unlike standard 6mm–9mm thin weatherboards that sit flatter against the wall, extra-thick boards (typically 14mm to 16mm thick) create a prominent, pronounced overhang cast by sunlight. This creates rich depth, sharp architectural contrast, and a premium, solid look akin to traditional heavy timber cladding—without the rotting, shrinking, or warping risks.

In modern commercial construction, data centers, and industrial facilities, structural fireproofing and wall cladding require materials that balance fire safety, mechanical strength, and long-term durability. While traditional Magnesium Oxychloride (MOC) boards—commonly known as standard Magnesium Oxide (MgO) boards—have long been popular, industry professionals are rapidly upgrading to Magnesium Oxysulfide (MOS) boards.

MOS technology solves the critical moisture absorption, weeping, and metal corrosion issues historically associated with traditional MgO boards, setting a new benchmark for fireproof cladding and structural subfloor panels.

Key Reasons ...

Modern data centers, commercial offices, and modular buildings demand high-performance flooring solutions that combine structural strength, fire safety, and environmental sustainability. Among emerging materials, Magnesium Oxide (MgO) boards have become the premier choice for Raised Access Floor (RAF) systems, outperforming traditional calcium silicate, cement, and particle board alternatives.

What is an MgO Board Raised Floor System?

A Magnesium Oxide board raised floor system utilizes high-density, glass-fiber-reinforced MgO boards either as a direct modular subfloor panel or as ...
