Fiber cement lap cladding is a highly durable exterior siding material made from a mixture of cellulose fibers, portland cement, sand, and water. It is designed to mimic the appearance of traditional wood siding—specifically “lap” or “clapboard” styles where each board overlaps the one below it—while offering significantly higher resistance to environmental factors.

Key Performance Benefits

• Fire Resistance: Most fiber cement products are ...

Fiber cement grooved weatherboards are a versatile cladding solution, designed to mimic the aesthetic of traditional timber tongue-and-groove planks while providing the durability of masonry. Because they are composed of pressurized sand, cement, and cellulose fibers, they offer significant performance advantages in both internal and external environments.

Technical Performance

• Fire Resistance: Typically classified as non-combustible (often reaching A1 ...

1. Zero Flame Spread & Low Smoke

MgO boards do not burn. In the event of a fire, they do not contribute fuel to the flames and, crucially, do not emit toxic smoke or “dripping” particulates, which are the primary causes of injury during building evacuations.

2. Structural Integrity Under Heat

Unlike plywood or OSB, which lose structural capacity quickly when charred, MgO maintains its shape and load-bearing properties for a longer duration under high temperatures. This is vital for maintaining “compartmentation” ...

Magnesium Oxide (MgO) boards with a Tongue & Groove (T&G) profile are increasingly used as high-performance subflooring and underlayment. They offer a robust alternative to plywood or fiber cement, particularly in environments requiring high fire ratings and moisture resistance.

Core Technical Specifications

MgO flooring boards are typically denser and thicker than standard wall panels to handle structural loads.

• Fire Rating: Most ...

For a 2-sided Tongue and Groove (TG) fiber cement decking board with dimensions of 2700mm x 600mm x 16mm, you are looking at a high-density, structural-grade panel typically used as a subfloor or finished floor base in modular construction or mezzanine applications.

Technical Specifications & Characteristics

For 12mm MgO Shiplap panels, the focus shifts from structural flooring to decorative and functional wall cladding (facades). Shiplap is highly valued in international markets like the US, Canada, and Australia for its superior water-shedding capabilities and “seamless” aesthetic.

The 12mm thickness is specifically optimized for vertical applications where weight and ease of installation are as important as fire resistance.

Key Technical Specifications (12mm)

For heavy-duty flooring applications, Tongue & Groove (T&G) MgO boards are often the gold standard due to their structural integrity and superior fire resistance compared to traditional plywood or OSB.

Here is a breakdown of the technical specifications, benefits, and installation considerations for T&G MgO flooring:

1. Key Technical Advantages

• Fire Rating: Most high-quality MgO boards are classified as non-combustible (Class A1/UL 050). They do not contribute to flame spread and maintain structural stability under high heat.
• Dimensional Stability: Unlike wood-based subfloors, MgO ...

Slip resistance for fiber cement decking is typically measured using two primary standards: the Pendulum Test Value (PTV) and the R-Rating (Oil-Wet Ramp Test). Because fiber cement is a manufactured product, the rating often depends on whether the board is smooth, textured (wood grain), or has a factory-applied anti-slip coating.

Common Slip Resistance Ratings

For most commercial and residential fiber cement decking products, you will find the following average ratings:

When using Tongue and Groove (T&G) Fiber Cement Board for flooring and underlayment, the focus shifts from aesthetics to structural integrity and moisture management.

In technical specifications, this material is often categorized as Structural Subflooring or Tile Underlayment.

Primary Flooring Applications

• Internal Wet Area Flooring: This is the standard for bathrooms, laundries, and kitchens. The T&G edges ensure the floor doesn’t “bounce” or deflect at the joints, which prevents floor tiles from cracking.
• External Decking Substrate: Used as a base for tiled balconies or ...

Yes, our Tongue & Groove (T&G) fiber cement boards are engineered as structural, self-supporting subfloor panels. They are designed to be fixed directly to timber or steel floor joists without the need for a secondary structural sub-base (such as plywood or OSB).

However, to ensure structural integrity and meet international building codes, the following parameters must be ...
