Installation of paroc Hvac Section GreyCoat T and paroc Hvac Bend GreyCoat T

paroc Hvac Section GreyCoat T and paroc Hvac Bend GreyCoat T is non-combustible stone wool pipe insulation for thermal and condensation insulation of pipework in buildings. It has a reinforced grey aluminium foil facing and tape in the longitudinal seam which prevents condensation and gives a quick installation.

General instructions

  • During the installation, both the object to be insulated and the insulation material should be at a minimum temperature of +10 Celsius.
  • Allow the temperature of the insulating material to adjust to the ambient installation temperature.
  • Always store the GreyCoat tape at room temperature.
  • Check that the surfaces to be joined with tape are clean and dry.
  • Ensure that pipe section seams are tight but without extra tension. The same applies at supports and other projecting parts.

Follow these instructions to insulate straight pipes:
