The Universal
ETICS Dowel Length

  • Always the right ETICS dowel length
  • Safe assembly owing to two-part concept
  • Insulation boards are fixed without thermal bridging (Chi value of 0.000)
  • Clean cut into insulation material

The Gecko U8 covers all common applications with only one dowel length. On glued and dowelled facades, the screw-in anchor supports the adhesive, allowing the external thermal insulation system to withstand even high wind loads.
