Thermal & Acoustic Insulation

Mineral wool, glasswool, elastomeric foam and reflective foil for roofs, pipework, plant and partitions — hot side, cold side and sound.

Insulation is three different problems that get treated as one. Keeping process heat in calls for mineral wool and calcium silicate. Keeping ambient heat out of a roof calls for a radiant barrier. Stopping condensation on a chilled line calls for a closed-cell material with the vapour barrier built in — and using the wrong one causes corrosion under insulation.

We stock for all three, plus the acoustic materials for partitions and studios, and the tapes, foil and sealants that finish the job.

  • Steam and chilled pipework lagging
  • Roof and ceiling insulation
  • Cold rooms and refrigeration lines
