  • To be used over hollow core, in-situ or supported metal deck concrete floors for new build or conversions.
  • Also designed to work with decking in an inverted flat roof.


Isocheck Cradle acoustic flooring system is designed to reduce impact sound transmission through uneven or cambered concrete floors by elevating the floor on timber battens that are supported by an adjustable plastic cradle.

The Adjustable Cradle comprises an injection moulded recycled plastic adjustable thread and supporting ring to ensure precise levelling across uneven concrete sub-floors without the need for conventional packers. Additional elevating blocks are available for applications where extra height is required.

The Cradle is New Build Robust Detail compliant for masonry floor construction and where the structural sub floor has a camber or is irregular and needs levelling. The treated floor meets with the New Build Robust Detail descriptive FFT2, typically within Robust Details E-FC-1, E-FS-1, E-FC-2 and E-FC-7.

Features and benefits:

  • Facilitates the incorporation of services and water-based underfloor heating systems.
  • Lightweight and easy to install.
  • Made from recycled plastics.
  • Precise height adjustment.
  • Gradient adjustable.
  • Resistant to changes in ambient temperature.
  • Not biodegradable.
  • When correctly installed will resist movement of the levelled floor surface.
