20mm XPS Grooved Cement Coated Board Overlay (16mm Pipe)

A pre-routed, cement-coated XPS panel, designed for use with water-based
underfloor heating systems. These overlay panels are made from high-density
XPS (300 kPa), which is thermally insulating, lightweight, waterproof, and faced
with a reinforced cement coating. The panels offer a quick and easy solution for
the placement of pipework in both domestic and commercial underfloor heating
applications. The lightweight, reinforced cement facing provides a robust surface
that is ideal for direct bonding of tiles. Many other types of finish, such as
engineered wood, carpet, vinyl, etc., can also be used with additional preparation
of the panels.

These panels are ideal for installation on solid floors, such as concrete, screed,
and asphalt floors, as well as suspended timber floors that have been boarded
with suitable floor boarding, such as tongue-and-groove planking or chipboard
planking. The panels are easy to cut and install and should be laid with the panel
joints staggered in a brick bond style. The routed channels are compatible with
most flexible low-pressure underfloor heating pipes. The panels are designed for
use over existing floors, providing a low-height build-up and insulated floor.

SPECIFICATION:

Size: Length- 1200, Width- 600, Depth- 20mm (Each panel = 0.72m²)
Construction: XPS – Grade 300 kPa
Design: 4 grooves @ 150mm centres + radius returns with 3 straight runs at the top of each panel for flow and returns

SUITABLE FOR
In most situations, no additional board is needed, and flooring can be laid directly on
the upper surface.
Wood flooring should be installed using a suitable underlay as per the manufacturer's
 instructions. Flooring-grade tiles can be applied using a suitable combed tile
adhesive layer.
For other types of finishes, a separating layer of Construction Board may be needed
before proceeding with the installation.
INSTALLATION
These Cement Boards allow for quick installation over a flat, level subfloor. They can
also be applied over various other substrates, provided they are fully supported and,
where necessary, used in conjunction with a damp-proof membrane (DPM).
TIMBER BASE
When installing on timber surfaces, the panels should always be secured with
mechanical fixings and washers. The fixings must be of an appropriate length for the
specific application.
CONCRETE BASE
For installations directly onto concrete, the boards should be adhered using a layer of
combed tile adhesive (S1 or equivalent). In some cases, mechanical fixings may also
be required depending on the substrate.
FINISHING
The Cement Board is suitable for both new construction and retrofit installations.
