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 density difference between LEAO® Lightweight Non-combustible Board and Fiber Cement Board?
LEAO® Lightweight Non-combustible Board has a density of 850 kg/m³, making it lightweight and easy to handle. In contrast, Fiber Cement Board has a much higher density of 1300 kg/m³, which is heavy and increases handling costs.
How does the workability of LEAO® Board compare to Cement Board?
LEAO® Board can be easily cut with a utility knife, providing convenient and quick operation. Fiber Cement Board requires cutting with a diamond saw and other specialized tools.
What are the fire performance and smoke toxicity ratings of LEAO® Board?
LEAO® Board is inherently Class A1 Non-combustible and achieves a Class AQ1 smoke toxicity rating, meaning it is completely safe and produces no smoke or toxicity.
Does LEAO® Board release formaldehyde or warp under damp conditions?
No, LEAO® Board contains no formaldehyde. It is moisture-resistant with a damp-proof expansion rate of ≤ 0.2%, making it highly dimensionally stable and not prone to mold or termites compared to wood-based fire-retardant boards.
What are the main application systems for LEAO® Lightweight Non-combustible Board?
It is used as a substrate for soft/hard wall panels, a reinforcing underlay for heavy objects, wall sheathing in light-gauge steel framing, composite flooring underlayment, light troughs, curtain boxes, partition panels, and in railway carriages or ship cabins.
