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 of LEAO® Lightweight Non-combustible Board compared to 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 density of 1300 kg/m³, which is heavy and leads to higher handling costs.
How easy is it to cut and work with LEAO® Lightweight Non-combustible Board?
LEAO® board offers excellent workability and can be easily cut with a utility knife for convenient operation. This is a significant improvement over Fiber Cement Board, which requires specialized tools and a diamond saw to cut.
What are the fire and smoke safety ratings of LEAO® Lightweight Non-combustible Board?
LEAO® board is inherently Class A1 Non-combustible. It achieves a Class AQ1 smoke toxicity rating, meaning it is completely safe and produces no smoke or toxicity in fire conditions.
Does LEAO® Lightweight Non-combustible Board release formaldehyde?
No, LEAO® Lightweight Non-combustible Board contains no formaldehyde, unlike wood-based fire-retardant boards which must meet specific limits (like E1 standards) to be used.
How does the board perform in damp environments?
LEAO® board is highly moisture-resistant and is not prone to mold or termites. It is dimensionally stable with a damp-proof expansion rate of ≤ 0.2%, compared to wood-based boards which expand > 3% and are prone to warping, cracking, and mold.
What are the primary applications of LEAO® Lightweight Non-combustible Board?
It is used as a substrate for soft/hard wall panels, an underlay for heavy objects, wall sheathing in light-gauge steel framing, composite flooring underlayment, partition panels, ceiling/wall panels, and in railway carriages or ship cabins. It supports direct render, decorative veneers, and ceramic tiles.
