System features

  • Rafts are radiant panels which are suspended from a flat structural soffit
  • Radiant Service Rafts incorporate a radiant heat emitter, with luminaires, acoustic treatment and other building services
  • High level installation and robust construction materials ensure product durability in demanding environments
  • Easy to clean
  • Frees up floor and wall space
  • Rapid warm up times, due to low water content

Standard Sizes

Radiant Modules are available in a range of standard lengths:

  • 1200mm
  • 1800mm
  • 2400mm

Longer runs combine multiples of the standard lengths to achieve the desired dimensions. This means long Radiant Module designs can be achieved without additional pipework, valves etc. 

Standard Finish

  • Coating – Polyester powder coat
  • Colour – RAL 9010 (Pure White)

Special & Non-standard Finishes

  • Available in full range of standard RAL colours
  • Anti-bacterial Coating (SAS AB)*

Other specialist powder coat finishes are available on request. For more information on non-standard finishes, please contact our technical services team.

*Radiant Modules and Rafts offer flat smooth faced radiant heating surfaces, with an optional anti-bacterial coating. AB is a polyester powder anti-bacterial paint, which is both durable and inhibits the growth of bacteria such as MRSA and E. coli on the coating surface (e.g. in healthcare and catering environments).
