Description
This pre-insulated pipe combines the same PEX/AL/PEX multilayer core used across the RIIFO range with a 13mm closed cell foam insulation layer, offering a ready-to-install solution for underfloor heating, cooling and water distribution projects. The insulation is independent of the pipe itself, which helps absorb sound and vibration in addition to reducing heat loss along the run.
The foam jacket carries a Class B fire rating and a low water absorption rating, making it a suitable choice where fire performance and long term moisture resistance are important considerations. A thermal conductivity of no more than 0.038 W/(mK) keeps heat loss to a minimum, supporting energy efficient system design across both individual dwellings and larger distribution networks. The pipe itself retains the flexibility and stability associated with multilayer construction, allowing it to be routed with fewer joints than a rigid alternative.
Supplied in colour coded coils, red for hot water lines and blue for cold, the product simplifies identification during installation and reduces the risk of connection errors. Working across a temperature range of -40°C to +95°C and pressures up to 10 bar, it is built to the same ISO 21003 standard as the bare multilayer pipe, with an expected service life in line with the wider RIIFO system.


Key Features & Benefits
- Pre-insulated for convenience: The foam layer is factory applied, removing the need for separate lagging on site.
- Class B fire-rated: Offers a defined level of fire performance for the insulation layer.
- Low water absorption: The closed cell structure resists moisture ingress, supporting long-term performance.
- Energy efficient: Low thermal conductivity minimises heat loss across the pipe run.
- Colour-coded coils: Red and blue jackets make it easy to distinguish hot and cold lines during installation.
- Sound and vibration resistant: The independent insulation layer adds a degree of acoustic dampening not present on bare pipe.
