Pipe Section Mat (PSM) consists of a rigid foil-faced slab with factory-machined grooves on the inside face to specifically suit large pipe diameters. The distance between the grooves is calculated to ensure that Pipe Section Mat (PSM) closely fits the pipe with all grooves tightly butted together.

It is designed for HVAC applications for pipework above 406 mm in diameter. The product is recommended for service temperatures of up to 700ºC.


  • Excellent thermal and acoustic insulation for large-diameter pipes and vessels.
  • Easy to handle and install due to flat-pack supply.
  • High temperature use.
  • High compressive strength.
  • Ideal for use where storage space is limited.

Conforms to BS EN 14303:2009.
