Floating Floor

The Polypipe Floating Floor System is designed for use in applications where a solid floor installation is not suitable due to structural weight limitations or where a ‘dry build’ floor option is required. Suitable for use in either new build or existing properties, the floating floor panels can be installed directly on top of both solid and timber floors.


The 50mm thick high density polystyrene panels have a thermal value of 0.036W/mK and can be used to enhance the thermal insulation requirement of the floor structure as necessary under current Building Regulations.


However, care should be taken when installing floating floor panels on top of a primary insulation layer to ensure that excessive deflection does not occur in final floor construction. It is therefore recommended that any other insulation materials used below the floating floor panels are of a high density construction (100kN/m2 at 10% compression min).


Features & Benefits of using the Floating Floor system:

  • Dry system – no screed and drying time
  • Suitable for projects where access to wet screed may be difficult
  • Provides impact sound installation when installed on intermediate floors
Material Requirements (Approx.)
Pipe 4.5m length/m²
End returns 0.5 x end return per panel
Floating Floor Panel 0.96m² per panel
Floating Floor installation guidance
  • Step 1: Laying end returns

    Begin by fitting a row of end return panels along one wall of the room. The end return panels should be suitably fixed down to the sub floor using screws.

  • Step 2: Laying the panels

    Lay the first line of panels ensuring that the grooves in the end returns are aligned correctly with the grooves in the panels. Use short lengths of pipe to ensure this alignment.

  • Step 3: Complete the row

    When you reach the opposite wall, place two more end returns in place and if necessary measure and cut a panel to suit to complete the row.

    Cutting the panels Panels can be cut using a handsaw.

  • Step 4: Repeat procedure

    Repeat this procedure until the floor area is complete

  • Step 5: Apply self-adhesive tape

    At this point apply the self adhesive foil tape to the vertical joints in the panels to hold them securely in place.

  • Step 6: Laying the pipe

    Starting from your manifold position and allowing enough pipe for connections, lay the pipe into the grooves of the OverlayTM Lite 15 panel in accordance with any design documentation.

  • Step 7: Complete installation

    Once the pipe has been laid complete the installation by taping up all of the remaining joints including those where the panels meet the end returns.

  • Step 8: Finishing

    The room can then be finished by fitting 18mm or 22mm tongue and groove sheets of chipboard, glued on the edge, over the floating floor system. Mark the position of the pipe where door thresholds or carpet strip are to be installed. When laying a ceramic or stone floor covering ensure that any deflection in the floor is minimised. It is recommended that a slip mat or uncoupling membrane is used rather than a second layer of wood.
