Not every underfloor heating project has the same requirements. While some floor constructions require highly specified acoustic systems, others benefit from a straightforward solution that combines underfloor heating, thermal insulation and acoustic performance within a single board.
FIBREfon® FLO has been developed as part of the CELLECTA underfloor heating range to provide a practical solution for projects where simplicity and reduced floor build-up are priorities.

A Combined Underfloor Heating, Thermal and Acoustic Board
FIBREfon FLO is a routed wood fibre board that combines:
UFH routing
Thermal insulation
Acoustic performance
within a single board.
Manufactured from recycled and recyclable wood fibre,
FIBREfon FLO has been designed for both new build and refurbishment projects.
Key features of FIBREfon FLO include:
UFH board with superior acoustic properties
Manufactured from recycled and recyclable wood fibre
Precision routed to suit 12mm, 15mm and 16mm UFH pipe diameters
Available in 150mm and 200mm pipe centre options
Lightweight and easy to handle during installation
Suitable for both new build and refurbishment applications
Technical Information
FIBREfon FLO is available in a 24mm board format measuring 600mm x 1200mm, providing 0.72m² coverage per board.
The board has a thermal conductivity of 0.048 W/mK and is compatible with CELLECTA ULTRAplate 1i heat diffusion plates and CELLECTA YELOfon ES5 perimeter edge strip.

Typical Applications
FIBREfon FLO is suitable for a range of floor constructions where underfloor heating, thermal insulation and acoustic performance are required.
Applications include:
New Build Projects
FIBREfon FLO can be incorporated within intermediate concrete floor constructions alongside CELLECTA flooring components including ScreedBoard 20, ULTRAplate 1i and YELOfon perimeter edge strips.
Refurbishment Projects
The board is also suitable for refurbishment applications, providing a practical routed solution for underfloor heating installations.
Intermediate Concrete Floors
FIBREfon FLO can be incorporated within intermediate concrete floor constructions alongside other CELLECTA flooring components, including ScreedBoard 20, ULTRAplate 1i and YELOfon perimeter edge strips.
Part of the CELLECTA UFH Range
FIBREfon FLO sits alongside CELLECTA's wider underfloor heating range, providing another option for specifiers, contractors and developers seeking a simplified floor build-up.
Whether the priority is acoustic performance, floor height, installation simplicity or overall floor design, selecting the most appropriate system early in the project can help streamline the construction process.
