Panel RENOVA, composed of a rigid plastic sheet provided with special bosses that
allow installations with special high modulus and high flexural strength screeds which
allow reduced thickness above the pipe, obtaining systems particularly suitable for
renovation; the lower part of the sheet is provided with an adhesive layer in order to
apply the panel to the pre-existing layers of paving. The knob bosses are designed
for use with DN17 mm pipes and suitable for installation centre distances that are
multiple of 50 mm; suitably dimensioned perimeter bosses to allow a rigid connection
by overlapping the panel’s sides, ensuring a perfect coupling and alignment between
the panels themselves.
Use
The RENOVA panel consists of a moulded rigid plastic sheet with special perforated
bosses, and is designed to allow the installation of an underfloor radiant system with
screed in buildings with low available thickness or where a low thermal inertia of the
850
radiant system is required.
• The rigid covering sheet, with shaped bosses with special holes, allows the
passage of the screed material inside the bosses themselves, allowing filling and
thus obtaining a uniform thickness of the screed;
• The bosses, shaped with appropriate reinforcement lines, allow a high degree of
compressive strength during installation;
• The bosses, shaped with appropriate finger grip clips, allow an easy insertion of the
17-mm pipe of the radiant system while ensuring it is held in position;
We recommend coupling with Polystop pipe in order to avoid tensions and possible
lifting.
To be used with specific screeds, see pages 19, 22, 23.
* Equivalent value for the rigid sheet compared to EPS bosses.
