Application Systems
LEAO® Lightweight Non-combustible Board serves as a versatile substrate for a wide range of applications. It is an ideal base for creating both soft and hard wall panels, and its high strength allows it to function as a underlay for heavy objects and a reinforcing underlay for decorative structures. It is perfectly suited for use as wall sheathing in light-gauge steel framing and as an underlayment for composite flooring. Furthermore, it is extensively used in practical elements like light troughs and curtain boxes.
Its utility extends to acting as a partition panel in composite walls, as well as in the construction of railway carriages and ship cabins. The board can also be directly installed as ceiling and wall panels. It offers excellent compatibility with subsequent finishing processes, including direct render, various decorative veneers, and stick ceramic tiles.
Frequently Asked Questions (FAQ)
What is the fire performance rating of LEAO® Lightweight Non-combustible Board?
LEAO® Lightweight Non-combustible Board is inherently Class A1 Non-combustible, meaning it provides maximum fire protection without requiring additional chemical fire-retardant treatments.
How does the weight and density of LEAO® Board compare to standard Cement Board?
LEAO® Board has a density of 850 kg/m³, making it lightweight and easy to handle. In contrast, standard Fiber Cement Board has a density of 1300 kg/m³, which makes it significantly heavier and costlier to transport and install.
Is LEAO® Board easy to cut and work with?
Yes, LEAO® Board offers superior workability. It can be easily cut using a simple utility knife. Standard Fiber Cement Board requires cutting with a diamond saw and specialized tools.
Does the LEAO® Board release formaldehyde or toxic smoke during a fire?
No, LEAO® Board contains zero formaldehyde and has a Class AQ1 smoke toxicity rating, meaning it is completely safe and produces no smoke or toxic fumes in fire conditions.
How does LEAO® Board perform in humid or damp environments?
LEAO® Board is highly moisture-resistant, with a damp-proof expansion rate of ≤ 0.2%, making it dimensionally stable and not prone to mold or termites. Traditional wood-based boards have an expansion rate > 3%, making them prone to warping, cracking, and decay when exposed to moisture.
What are the primary applications of LEAO® Lightweight Non-combustible Board?
It is widely used as a substrate for soft/hard wall panels, underlayment for heavy objects or composite flooring, wall sheathing in light-gauge steel framing, partition panels, light troughs, curtain boxes, and in the construction of railway carriages and ship cabins.
