Overlay™ Lite 15

OverlayTM  Lite 15 is a slightly deeper profile which can be used on top of a supporting floor as a low profile alternative to floating floor. The system delivers the same responsive heat but is configured to be more suitable for larger ‘whole house’ projects.

 

Features & Benefits of using the OverlayTM Lite 15 system:

  • Low profile system (22mm deep)
  • Uses 15mm pipe so uses fewer circuits
  • No need to excavate existing floor
  • Simple installation
  • Suitable for multiple floor coverings
  • Lightweight pre-grooved boards
  • Ideal for whole house applications
  • Fast response times

 

Optimal floor coverings:

  • Laminate
  • Engineered Wood
  • Carpet

Overlay™ Lite 15 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: Cutting panels

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

    Cutting the panels
    Panels can be cut using a handsaw.

  • Step 4: Repeat

    Repeat this procedure until the floor area is complete.

  • Step 5: Secure the panels

    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 Overlay™ Lite 15 panel in accordance with any design documentation.

  • Step 7: Taping the remaining joints

    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

    Laminate and engineered wood can be laid directly over Overlay™ Lite 15 floor panels. Where carpet is being fitted, first fix a 6mm MDF or 10mm plywood using a contact adhesive, then continue to lay the floor covering as normal. It is advisable to mark out pipe positioning to avoid stapling pipes when fitting carpets.
