Making it Child’s play to replace lead water services

  • Lead pipe replacement in two hours or less
  • No digging up floors or trauma
  • Cost effective / efficient use of labour

Insuduct Logo

Insulated ducting, is designed to protect up to three 32mm OD water pipes from frost outside the thermal envelope of a building: for use with Groundbreaker, Firebreaker or on its own.

Designed to facilitate the replacement of lead or leaking water service pipes in less than two hours without the trauma of having to dig up floors etc.

INSUduct has been designed to not only comply with, but to exceed standards laid down by BS5422 and within Water Regulation (4) including “extreme” weather conditions.

INSUduct is very simple to install on new or existing dwellings, making it the perfect solution to replacement of leaking or lead pipes or any urban regeneration project.

INSUduct can also “climb” to first, second or higher floors, thus removing the need to bring water services in at any level.

Fabricated in reprocessed materials to meet the green agenda.

To protect pipes larger than 32mm OD, we can fabricate (bespoke) INSUduct for pipes up to 63 mm OD and possibly larger – please contact Plastics Express, our appointed distributor for further details as required.
