NuPanel®/NuClad® is an eco-friendly high performance autoclaved calcium silicate board endorsed by third party accreditation bodies for green building product label. It does not contain any harmful substances or inorganic fibres and is free from formaldehyde and toxic emissions. NuPanel®/NuClad® is versatile for both internal & semi-exposed use which has high level of performance in the presence of severe damp environments and is good resistance to fire. The superior non-flammable nature of NuPanel®/NuClad® conforms to non-combustible when tested in accordance with European Building Classification EN 13501-1: Class A1, BS 476: Part 4. The board has good thermal insulation and resists to continuous operating temperature up to 80°C. NuPanel®/NuClad® partition is capable to provide 60 minutes fire resistant period as well as high level of impact sound insulation.

NuPanel®/NuClad® is an European CE marked building board and conforms to durability tests BS EN 12467- Category C sheet, which is intended for applications subject to heat and moisture. It is robust and lightweight for use in dry construction. NuPanel®/NuClad® is versatile for general internal uses and direct weathering applications when used in conjunction with external grade texture finish or tiling in new construction or refurbishment projects. Unlike wood based panels, gypsum plasterboards or magnesium silicate boards, NuPanel®/NuClad® is durable and immune to insects and vermin, unaffected by dilute chemicals. It is dimensionally stable and will not warp, swell or decay in wet area. Also an ideal economical building board material with good thermal and acoustic properties replaces conventional non-loadbearing masonry wall constructions.

NuPanel®/NuClad® is off-white in colour and has a sanded smooth surface 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 cellulose fibres and special fillers enabling NuPanel®/ NuClad® to be robust for impact resistance. The board has
undergone a sophisticated process and autoclaved curing process where high pressure and high temperature steam is induced to ensure a complete chemical transformation to crystalline structure, thus providing the board with excellent dimensional stability at humid or damp environments and chemical resistance.

NuPanel®/NuClad® contains no water soluble additives and will not rot, degrade or deteriorate. The fibre-reinforced calcium silicate
matrix will absorb water causing some loss of strength, which is fully recovered on drying. Any staining on the board caused by leakage can be easily painted over. Moisture will not cause leaching or efflorescence and has no permanent effect on NuPanel®/NuClad®. It is simple to work with and easy to decorate. NuPanel®/NuClad® is manufactured to Quality Management System Certification ISO 9001, Environmental Management System Certification ISO 14001Hong Kong Green Label as well as Singapore Green Label.




NuPanel®/NuClad®  is versatile for both internal & semi-exposed use which has very high levels of performance in the presence of severe moisture. The fibre reinforced calcium silicate matrix allows NuPanel®/NuClad® with good flexural strength and resistance to impact. It is easy to curve, cut and fix. It can be used in a wide variety of building applications. Typical applications include:

  • Access panels in wet area

  • Aesthetic casings for building services

  • Backing wall for ceramic tiling in wet area

  • Backing boards for metal claddings

  • Decorative and moisture resistant ceilings

  • Fire resistant and acoustic insulated partitions

  • Perforated ceilings & wall panels

  • Semi-exposed roofing, eaves, soffits and sunscreens



NuPanel®/NuClad® is low carbon foot print, CE marked non-combustible calcium silicate matrix board to EN 13501-1:
Class A1. It has superior fire resistance performance and excellent dimensional stability at heat or severe humid environments. The crystalised monolithic structure of NuClad®/NuPanel® as a reliable substrate ensure to hold paint finishes longer than other building board at damp and wet areas.
