ISOFLOW Pre-Insulated Quadruple Pipe:

Maximise energy efficiency and simplify installation with Isoflow pre-insulated underground quadruple pipe, a compact solution combining heating and hot water flow and return in a single fully insulated duct.  

Designed for flexibility and durability, Isoflow reduces the need for underground joints by allowing the pipe to curve directly out of the ground, removing the need for elbows and keeping the PEX-a pipe and insulation jacket fully continuous.

Key Features of Isoflow Pre-Insulated Quadruple Pipe:

  • Minimises joints and reduces installation time

  • Continuous PEX-a pipe and insulation jacket for durability

  • Excellent thermal performance for efficient combined heating and hot water distribution

  • Ideal for combined transfer of heating and hot water in residential and commercial projects

  • Cut-to-length with next day delivery on stock product

A full range of fittings is available, including tees and insulation kits, supporting complete pre-insulated pipe system installations

Multiple sizes and configurations in stock. Contact Flowsupplies today to request a quote and benefit from expert advice on all things pre-insulated pipe in the UK.
