  • Provides an effective DPC and thermal barrier between frame, inner and outer wall leaf.
  • Exceeds the minimum thermal resistance path of 0.45m2K/W stipulated in Robust Details ‘limited thermal bridging and air leakage’
  • Rigid profile extrusion
  • Integrated and flexible water strip to reduce air leakage
  • Simple on-site trimming to cope with ‘rogue’ cavity widths
  • Can be built in with PVC ties as brickwork progress or simply nail to block
