Insulation Specification
RIIFO pre-insulated pipes provide an innovative, energy-efficient solution for underfloor heating, cooling, and water distribution. These systems deliver secure, long-lasting performance by combining excellent heat-loss reduction with high flexibility and easy installation. They offer highly effective pipeline insulation at a low initial cost, suitable for both individual buildings and larger local distribution networks.

Description
Combining a PEX/AL/PEX multilayer pipe core with a 20mm foam insulation jacket, this coil is built for projects where a thicker layer of insulation is preferred, whether for longer pipe runs, larger diameter systems, or installations where minimising heat loss matters more than saving space. The foam sits independently around the pipe, adding a degree of sound and vibration damping alongside its thermal performance.
With a thermal conductivity of 0.038 W/(mK) and a Class B fire rating, the insulation is suited to underfloor heating, cooling, and water distribution schemes across both domestic properties and larger networks. Its closed cell structure keeps water absorption low, which matters for long-term durability wherever the pipe run isn't fully protected from moisture. Beneath the insulation, the multilayer pipe itself brings the flexibility to navigate bends without extra fittings, while holding its shape once installed.
Coils are colour coded, red for hot water and blue for cold, so installers can identify pipe runs at a glance during first fix. The pipe is rated to -40°C through +95°C and up to 10 bar, built to ISO 21003, and shares the same expected service life as the rest of the RIIFO system, giving a consistent standard of performance whichever insulation thickness is specified.
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.
