Surface Preparation

  • Hand Tool Cleaning


Densofil is designed to insulate fittings preventing the formation of condensation which protects against corrosion. This lightweight material is perfect for moulding around awkward items such as valves, fittings, flanges and more.

It can also be used to seal the space between insulated pipes and their ducts for service entries. Denso Tape or Denso ColourTape can be used to protect it from damage and moisture.

Densofil should not be used with absorbent insulating material.
