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.
