Application

Suitable substrates include concrete, sand:cement screed and timber floors, plus brick/ block surfaces; also suitable for under-tile heating. Norcros Prime Bond is recommended to be used on substrates before installation.

Description

A high-performance mineral-based construction/ tile backer board manufactured using a process which produces very little CO2 emissions, unlike cement-particle and gypsum boards which both generate high levels of CO2. The boards are silica and asbestos-free and are non-nutritious to mould, fungus or insects.

The board is dimensionally stable when wet and is not affected by changes in temperature, it is suitable for both internal and external applications. It is non-flammable and non-combustible, ideal for use with underfloor heating systems and in build-ups for fire-resistant systems and firewalls.

A 6 mm board can be used to replace a 15–18 mm WBP plywood to strengthen an existing timber floor. The 12 mm board can be used as an alternative to conventional plasterboard on interior walls and ceilings. Pro Ply can be bent to form curved columns.

Features and benefits:

  • Non-flammable (EN 13501 Class A1).
  • Strong, lightweight and easy to use.
  • Lightweight.
  • Suitable to receive tiles, paint, wallpaper and plaster skim.
  • Mould- and impact-resistant.
  • For internal and external use.
  • 12 mm board supports up to 80 kg/m².
  • Classified to EN 12467:2004/A1: 2005, EN 12467:2004/ A2: 2006.
