12mm Promat PROMAFOUR board is a 2500x1250mm strong, lightweight, non-combustible cement bonded calcium silicate based insulation board without inorganic fibres and do not contain formaldehyde. It can withstand high temperatures of up to 1000C and suitable as a wall lining surrounding high temperature output multi-fuel stoves for domestic and commercial properties. The board also offers low thermal expansion coefficients and low shrinkage, so there is no risk of cracking. The Promat PROMAFOUR board complies with the requirements of Building Regulations Part J (Combustion Appliances and Fuel Storage Systems). The board provides a thermal barrier and reflect the majority of heat back into a room providing a warm, cosy and pleasant living environment. Promat Promafour has a very smooth surface that does not need to be plastered. The boards can be painted with minimal preparation to achieve a decorative finish.

To line the walls surrounding a high temperature output multi-fuel stove for domestic and commercial properties.

INSTALLATION

  • The boards should be fixed at maximum 300mm fixing centres to a non-combustible background (either masonry or steel stud framework).
  • Boards should be pre-drilled with slightly oversize holes and the screws not over-tightened to allow for a degree of thermal movement.  
  • If fixed directly into block or brick, metal plugs and fixings should be used and not plastic ones.
  • A gap of at least 50mm should be left between the boards and the back of the appliance. Specific information relating to the minimum distances from the sides and top of the appliance to non-combustible materials, as well as more detailed information on hearth design from appliance manufacturer should be referred.  
  • As the board has a very smooth surface that does not need to be plastered.
  • If plastering is still desired, the boards should be fully sealed using an inorganic primer suitable for use at elevated temperatures.
  • The boards can be painted with minimal preparation to achieve a decorative finish. 
  • Promat PROMAFOUR should be decorated using silicate based paints. Prior to painting, the boards should be sealed using an inorganic primer suitable for use at elevated temperatures.
  • It can also be finished with wallpapers that are suitable for use at elevated temperatures. Prior to wallpapering, the boards should be sealed using an inorganic primer suitable for use at elevated temperatures.
  • Promat PROMAFOUR boards can be tiled. Screw boards at maximum 200mm centres to supports (maximum 400mm centres) before applying tiles. All board joints must be supported. The maximum tile weight should not exceed 30kg/m2.
