 Advantages in brief 
 FlexPipe
Flexible
pipes
 Ø 15-110 mm  0.022  Yes  Yes*
  • Available with different insulation thicknesses, Series 1, 2 and for relevant pipes Series 3.
  • Built-in diffusion barrier prevents deterioration of insulation properties.
  • Diffusion barrier is standard in FlexPipes - energy losses are greatest for small-diameter pipes.
  • Available with service pipes made of steel, PEX, aluminium/PEX or copper.
 TwinPipe 
Flexible
pipes
 Ø 15-50 mm  0.022  Yes  Yes*
  • Provides best possible insulation value.
  • Available with two different insulation thicknesses, Series 1 and 2.
  • Built-in diffusion barrier prevents deterioration of insulation properties.
  • Diffusion barrier is standard in FlexPipes - energy losses are greatest for small-diameter pipes.
  • Available with service pipes made of PEX, aluminium/PEX or copper.
  • Requires less civil works and fewer joints.
