    Castellated panels are a highly flexible tray system for screeded underfloor heating projects. The lightweight panels allow for fast installation alongside accurate fixing of underfloor heating pipes ensuring accurate spacing of pipes allowing a even heat distribution.

    Castellated trays can be cut to fit any room shape and interlocked to create a fully interlocking continuous grid floor panel ready for the pipes which can be fixed at multiples of 50mm pipe centres, allowing total flexibility for all heat sources such as heat pumps, boilers etc.

    Benefits include:

    • Quick and efficient to install
    • Very low profile
    • Trusted system for screeded underfloor heating
    • Pipe centres to multiples of 50mm
    • Pipes completely surrounded by screed
    • Options with or without insulation
    • Options with film or film and adhesive
