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 ...

Fiber cement is an engineered composite material made from Portland cement, sand, water, and cellulose fibers. When manufactured into heavy-duty flooring sheets with a Tongue and Groove (T&G) edge profile, it provides a seamless interlocking system designed to distribute weight evenly across floor joists.

The specific dimensions—2700mm x 600mm x 19mm—are meticulously engineered to fit standard framing intervals, reduce installation waste, and provide a rigid, heavy-duty platform suitable for a wide range of floor finishes.

Key Technical Advantages of 19mm T&G Fiber Cement ...

Compared to traditional masonry, metal composite panels (ACM), or standard EIFS, fiber cement rainscreen systems offer a distinct combination of structural resilience and design flexibility:

Superior Fire Safety: Premium fiber cement panels typically achieve A2-s1,d0 non-combustible ratings (in accordance with EN 13501-1 / ASTM E136), making them compliant with stringent high-rise and commercial building fire codes.

Exceptional Durability & Longevity: Manufactured using high-pressure autoclaved technology (combining cement, cellulose fibers, and selected minerals), these panels resist rotting, warping, UV degradation, and freeze-thaw cycles, offering ...

The non-corrosive nature of premium MgO subfloor panels relies entirely on their chemical matrix:

  Magnesium Sulfate Formulation (): By replacing Magnesium Chloride () with Magnesium Sulfate, the manufacturing process eliminates free chloride ions.

  Zero Leaching: Sulfate-based boards do not exhibit hygroscopic (moisture-attracting) pulling of ambient water in high-humidity zones. Because the board stays dry internally and lacks chlorides, it will not degrade or corrode steel joists, light-gauge steel framing, or subfloor fasteners.

  Acoustic & Structural Integrity: The resulting matrix is ...

When comparing Magnesium Oxide (MgO) Tongue & Groove (T&G) Panels to traditional subflooring materials—primarily Oriented Strand Board (OSB) and Plywood—the choice comes down to a balance between high-performance durability and upfront material costs.

MgO panels have rapidly gained traction in commercial, modular, and high-end residential builds due to their superior material properties. Here is a detailed breakdown of how they stack up against traditional options.

Technical Performance Comparison

Magnesium Oxide (MgO) cladding panels are high-performance exterior and interior wall systems that have become a preferred alternative to traditional fiber cement, stucco, and wood cladding. Composed of magnesium oxide, natural minerals, and fiberglass mesh reinforcement, these panels offer ultimate structural protection.
