Kaiflex ST Tubes

Flexible closed cell rubber insulation, Kaiflex ST reliably prevents against condensation and reduces energy loss.  With a water vapour barrier incorporated into the insulation cell structure Kaiflex ST retains thermal performance over the entire life of the system.

Kaiflex ST tubes are 2 m long and can be supplied unslit for sleeving onto pipes during installation or pre-slit for insulating existing pipework.

In addition to preventing condensation and saving energy, Kaiflex ST also performs an acoustic function.  With inherent anti-microbial resistance as standard and a Class O fire rated rubber that is dust and fibre free, Kaiflex ST can be used in any kind of public, commercial or industrial building.


  • Closed cell structure with in-built water vapour barrier.
  • Inherently resistant to corrosion.
  • Excellent thermal values minimise energy loss.
  • Flexible, dust and fibre free nature.
  • Inherent resistance to microbial growth.
