Floor Construction – Water Underfloor Heating
After checking that all the components are included in the packaged it is time to prepare for the
installation of the underfloor heating pipe.
Make sure that the floor is level and clean and the
room is empty. Next install your floor insulation (not
supplied). We recommend a minimum of 50 mm highdensity
(Polyurethane) insulation. Such as Celotex or
Kingspan. High density insulation’s have better
insulation properties and allow the use of pipe clips.
These brands can be bought from most builders
merchants. The clips need the high-density
insulation to stay in place. If Polystyrene is used,
then a lightweight mesh e.g. ref D49 needs to be
installed on top of the insulation and the pipe tied to
the mesh.
Note, some insulation board manufacturers recommend that you tape the joints to prevent screed
ingress, which can form cold bridges.
