Denso Flashing Tape


Densofil is designed for contouring around complex shapes such as valves, flanges etc. and filling cracks and cavities in preformed insulation sections ensuring a minimum thickness of 50mm over the metal surface. It is simply pushed into place and smoothed to the required profile by hand.

Use of the compound insulates the fittings and inhibits the formation of condensation which in turn prevents corrosion.


Lacquered aluminium foil finish suitable for heavy- duty applications. It gives a long lasting seal. Also available in rolls up to 600mm wide.

When used in combination with Denso Flashing Tape Primer the self adhesive tape has excellent adhesion to most common roofing materials and is perfect for repairing damaged and worn flashing's, sealing lead sheeting, replacing lead, repairing valley gutters, sealing gutters and down pipes and also provides a decorative finish.

Can be rapidly applied to provide an effective gas and watertight seal capable of accommodating movement due to settling, subsidence or vibration (where ducts are wet or a substantial head of water could form, Densoseal 16A should be used)

  Recommended for profiling around irregular shaped pipe fittings particularly where deep fillings are required. It is used with primer prior to overwapping with Denso, Densopol or Densoclad Tapes for long term corrosion protection of buried pipe fittings to P1* or P2* specification. Its low density gives resistance to slumping.
  Recommended for use on internal and external tanking to protect buildings and culverts from ingress of water and the effect of chlorides, sulphates etc.

To ensure thorough sealing at overlaps there is a double sided adhesive strip along the edge covered by a separate interleaving strip.
