Traditional new build and existing cavity walls, solid masonry walls, some types of framed and sheathed walls or pre-cast concrete walls where the window or door frames are inset into the structural opening and not projecting from a backing wall.

Cavity wall reveals must be closed off with a proprietary thermal cavity closer, blockwork or similar return to the outer leaf. Existing cavity and solid masonry wall reveals may need to be made good. Damaged or excessively undulating masonry should be levelled off with sand and cement render to provide a flat as possible surface. illmod TP654 Trio 1050 is applied directly to the head an jamb of the frame immediately prior to the final installation of the window or door. The cill section of illmod TP654 Trio 1050 is applied to the substrate of the structural opening and bonded with illbruck SP525.


illmod TP654 Trio 1050 is a three layer pre-compressed multi-functional window and door sealing tape based on two new technologies incorporating a proprietary airtight membrane layer running through the entire width of its core. Certified Passiv-haus levels of airtightness can be achieved.

Features and benefits:

  • Flexible.
  • Airtight.
  • Vapour permeable.
  • Driving rain resistance to 1050 Pa.
  • Thermal and acoustic insulation.
  • Emission class of EC1+.
