Underfloor systems for both heating and cooling
Thermoboard Underfloor Heating
Underfloor heating and cooling systems in forms to suit power-floated slabs, screeds, all forms of timber floor, acoustic 
floors and raised access floors are offered.
Introduction  Thermoboard draws 
on more than 30 years' experience 
of underfloor heating and is one of 
the leading UK suppliers, covering 
all aspects of both residential and 
light commercial sectors.
Thermoboard is a brand of Wavin 
UK, part of the Wavin Group, one of 
Europe's largest suppliers of plastic 
pipe systems and one of the 
originators of this technology.
Thermoboard's underfloor heating 
and cooling complements the 
requirements of Part L and Part E of 
the Building Regulations. Its 
systems provide many benefits in 
comparison with radiators and 
conventional air conditioning, being 
more comfortable, unobtrusive, 
efficient, quiet and safe.
Applications  Products suit any 
new build or refurbishment project, 
domestic or commercial.
Authority  The company is a 
founding member of the UHMA 
(Underfloor Heating Manufacturers 
Association), the UK trade association 
for all forms of radiant heating.
The systems and services offered 
conform to, and support the 
application of, EN 1264. The 
performance of systems falling 
outside the scope of EN 1264 are 
independently tested through the 
company's membership with BSRIA, 
a consultancy, test, instrumentation 
and research organisation.
Construction type - screeded
Staple System
Applications are small or irregular 
screeded areas and power-floated 
slabs.
Description  Pipe is stapled to an 
insulation layer or tied to mesh 
before screed or concrete is laid.
System Plates
Applications are general use for 
screeded floors; suit conventional 
and liquid screeds.
Description  1275 mm x 975 mm 
vacuum formed plastic sheets 
contain a regular array of clips to 
fully support the pipe at 0°, 90° and 
±45° angles with pipe spacing in 
multiples of 75 mm. Sheets are 
overlaid and interlocked when laying 
to create a layer ready to accept 
conventional or liquid screeds.
Pocketed Polystyrene*
Applications are general use for 
screeded floors; suit conventional 
and liquid screeds.
Description  2400 mm x 600 mm 
panels of extruded polystyrene 
insulation have channels cut into the 
top surface at fixed centres to suit 
the required heat output. At intervals 
the channels are widened to form 
pockets. The sections between the 
pockets grip the pipe and hold it in 
place, avoiding any need for mesh, 
staples, clip rails or screed plates.
Construction type - fully floating
Foiled Polystyrene
Applications are fully floating 
timber floor decks positioned above 
a flat and level sub-floor.
Description  Used instead of plain 
insulation, this product comprises 
2400 mm x 600 mm panels of 
extruded polystyrene with 
compressive strength of 200 kN/m². 
The panels have channels cut into 
the top surface, typically at 200 mm 
centres, providing an excellent base 
for a floating floor. Factory-fitted soft 
aluminium foil heat diffusers are 
bonded to the top surface. These 
conduct heat away from the pipe 
and into the floor deck. The panels 
are laid on-site and heating pipe is 
pressed into the pipe channels.
Construction types - battened or 
joisted
Modular Wood*
Applications are across joists at up 
to 450 mm centres (up to 600 mm 
when manufactured from ply). 
Product is ideal for refurbishment 
projects where joist centres are 
variable or over fabricated joists that 
must not be notched.
Description  Panels are  
2400 mm x 600 x 22 mm, P5 grade 
T&G chipboard with a serpentine 
length of 10 mm pipe fitted within 
the panel thickness from the 
underside. They are used in place of 
plain panels that are normally used 
to form a floor deck. Interconnections 
between panels are made using 
Wavin Hep2O push-fit fittings. The 
top surface is printed to show the 
position of the pipe within the panel, 
preventing accidental damage.
Timber Batten/Joist
Applications are joists and battens 
at 400 mm or 600 mm centres and 
where a continuous pipe installation 
is preferred to a modular system. 
System can be used with fabricated 
joists and most forms of acoustic 
battens. It is ideal for planked floor 
decks.

Description  Panels are 
2400 mm x 340 or 540 mm extruded 
polystyrene with pipe channels cut 
into the top surface and aluminium 
foil heat diffusers factory-fitted. The 
panels are fitted between the 
battens (or joists using brackets) so 
that the heat diffusers are flush with 
the timbers; pipe is then pressed 
into the channels. The panels 
eliminate the problems caused by 
systems that rely on heating the 
airspace beneath the floor deck and 
they avoid any need for counter 
battens.
Low profile system
Low build
Applications
 Any installation on a 
flat and level subfloor where 
minimum build up is required.  
Ideally suited to single zones up to 
26m
2
.
Description
1200 x 600 x 15 mm extruded 
polystyrene panel with channels at 
150mm centres, designed to take 
10mm Wavin UFH pipe. Universal 
panel incorporating end-return, flow 
and connect-through channels.  
Factory fitted aluminium diffuser 
layer ensures even heat distribution 
across the floor.
Construction Types - raised 
access floors*
Applications are heating and 
cooling in PSA-style raised access 
floors of 600 mm x 600 mm floor 
trays supported on pedestals.
Description  1200 mm x 100 mm 
cassettes of foiled polystyrene with 
pipe channels are supported by 
special brackets that attach to each 
pedestal. This ensures the top 
surface is directly in contact with the 
underside of the galvanized tray.

Heating pipe is pressed into the 
channels before the trays are finally 
fitted.  The heating panels do not 
obstruct access to services installed 
within the floor void.
SERVICES
A full design service is provided and 
installation method statements are 
available for each product. Installer 
training is available at the 
company's office or on-site.
