NuClad® is a high quality calcium silicate architectural board reinforced with selected cellulose fibres and fillers. It is 100% free from asbestos, sepiolite, inorganic fibres or formaldehyde. The board is versatile and suitable for general use of internal and direct weathering
applications when used in conjunction with external grade texture finish or other surface coating in new construction or refurbishment projects. It is an economical, non-combustible building board material to replace traditional concrete / clay block or cement-bonded particle board for the construction of non-load bearing elements. Unlike most plywood, cement-bonded particle boards, gypsum boards or magnesium boards, NuClad® is light weight, strong, moisture resistant, will not warp, swell or decay in wet area. The board is manufactured to ISO 9001 quality management system and ISO14001 environmental management system, and has obtained the Green Product Label Award issued by National Environment Protection Bureau. |

NuClad® is off-white in color and has a smooth finish on one side and a slightly textured reverse. It can be left undecorated or can be easily decorated with skim coat, wallpapers, paints or tiles. It consists of calcium silicate matrix reinforced with selected fibres and special fillers enabling NuClad® to be robust for impact resistance. The board is cured under an autoclaving process where high pressure and steam is induced to ensure a complete chemical reaction to form silicate structure, thus providing the board with excellent dimensional stability, moisture and chemical resistance.
NuClad® contains no water soluble additives and will not rot, degrade or deteriorate. The board will absorb water causing some loss of strength, which is fully recovered on drying. Any staining on the boards caused by leakage can be easily painted over. Moisture will not cause leaching or efflorescence and has no permanent effect on the board.
NuClad® has high water vapour permeability which helps eliminate condensation or water trapped behind the board. It is non-combustible when tested in accordance with BS 476: Part 4. The board provides a degree of thermal insulation and is resistant to continuous operating temperature up to 80°C. |

- Decorative and moisture resistant ceilings
- Bathroom and shower partitions
- Access panels in wet area
- Backing boards for tiles or marble claddings
- Aesthetic casings to M&E building services
- Industrial wall linings
- Perforated ceilings & wall panels
- Semi-exposed applications such as eaves, soffits and sunscreens

NuClad® is formulated without asbestos, sepiolite, inorganic fibres or formaldehyde. When using power saws or sanders in a confined space, dust extraction equipment is recommended to control dust levels. NuClad® is designed for non-load bearing construction. Horizontal boards or ceiling panels must not be walked on as they are not designed to take additional loads between supports; if there is a risk of this occurring, warning notices should be displayed. Fixers must ensure that they work from adequate and safe platforms where necessary.
Note: All physical performance values of products depicted in this catalogue are averages based on the standard production. The figures may be changed dependent on the test method used. |
