9mm Promat MASTERBOARD is non‑combustible, moisture‑resistant calcium silicate board designed for demanding internal and semi‑exposed applications where durability, fire safety and dimensional stability are essential. It provides a robust substrate for dry lining, partitioning and specialist linings, performing reliably in areas subject to intermittent moisture, impact or thermal stress. Masterboard is manufactured from autoclaved calcium silicate, giving it a dense, stable and non‑combustible core. It is suitable for both new‑build and refurbishment projects, offering excellent resistance to fire, moisture and impact. The board can be cut, drilled and fixed using standard tools, making it straightforward to install across a wide range of building elements. The board is off-white in colour and has a smooth unsanded front face with a sanded reverse face. It can be left undecorated or can be easily decorated with paints, wallpapers or tiles.

CHARACTERISTICS

  • Non‑combustible performance — Euroclass A1 reaction‑to‑fire classification.
  • Moisture‑resistant — suitable for areas with intermittent damp or humidity.
  • Dimensional stability — maintains shape under thermal and moisture variations.
  • Robust and impact‑resistant — ideal for high‑traffic or service areas.
  • Versatile substrate — compatible with tiles, renders, paints and specialist finishes.
  • Easy to work and fix — cuts and drills with standard site tools.

APPLICATION

  • Internal partitions and linings
  • Ceilings and soffits
  • Service areas and plant rooms
  • Semi‑exposed locations — e.g. covered walkways, sheltered external soffits
  • Wet‑area substrates — behind tiles in bathrooms, kitchens and utility spaces

CERTIFICATION

  • BBA Agrément Certificate No. 18/5593
  • Fire Reaction Class: A1 Non Combustible EN13501-1
