Stoves and Heating Appliances

The trend towards installation of free standing, wood-burning or multi fuel stoves and traditional gas appliances within existing hearths or cassette/inset type stoves within a false chimney breast, means that there is often a requirement for linings which are capable of withstanding high temperatures.

Promat has a number of fire protection and insulation solutions dependent on the type of installation being undertaken, as detailed below.

  • PROMAFOUR® System: ideal for building a false chimney breast for a cassette/inset type fire place. A safe reliable, robust chimney breast insulation system, developed to resist continuous high temperatures of up to 1000°C. 
  • PROMAFOUR® Boards: a non-combustible board which can withstand a maximum continuous operating temperature of 1000oC. Ideal for use as a lining behind a wood burning stove or heating appliance.
  • SUPALUX®a non-combustible board which can withstand a maximum continuous operating temperature of 80°C. Ideal for use behind a wood burning stove or heating appliance.

Heating appliances come in many formats and Promat strongly recommends that the heating appliance manufacturer and the flue or chimney manufacturers be consulted to ensure that the correct installation procedures are followed. Temperatures in excess of 80°C can have a severe effect on the overall structure where the heating appliance is mounted.


The area around a wood burning stove, for example, can reach up to 400°C which far exceeds the 45°C maximum recommended for plasterboard.

The main functions the board provides are:
  • Providing a flat, heat resisting lining to an existing hearth
  • Reflecting the majority of heat back into the room
  • Providing a thermal barrier capable of withstanding up to 1000ºC continuous working temperature, with a material which is inherently non-combustible


The requirements for the installation of heating appliances in buildings are covered by the Building Regulations in Approved Document J - Combustion appliances and Fuel Storage systems.

Within this document, Requirement J2 deals with the protection of building, and states that "Combustion appliances and fluepipes shall be so installed, and fireplaces and chimneys be so constructed and installed, as to reduce to a reasonable level the risk of people suffering burns or the building catching fire in consequence of their use."

Particular care is required to ensure that hot radiating surfaces are kept clear of combustible materials such as timber. Minimum distances are prescribed, and the use of non-combustible lining materials is indicated, and the guidance given must be followed at all times.

Please note that Promat have not performed any tests which allow the minimum distances from combustible material specified in Approved Document J to be reduced.
