Preliminary precautions

Installation

When installing the RENOVA ULTRA system, the system

becomes a floating floor and the conditions of the type of sub-

floor are no longer important, provided, of course, that the sub-

floor is able to support the weight of the system itself.

•

With the RENOVA ULTRA panel, we recommend the use of

•

POLISTOP BASIC DN14 pipe, because its malleability allows

installation without stresses that can lead to the lifting of the

panel or lift part of the bends of the pipe itself.

In order to obtain a radiant system with the maximum

performance, after taking the preliminary precautions listed

above, it is necessary to follow this procedure:

Install the expansion edge strip, with PE film, of appropriate

height;

Install the RENOVA ULTRA panel starting from the side

walls and fitting one panel on the other using perimeter

bosses;

Take care the PE film on the edge strip overlaps the

RENOVA ULTRA panels, covering their perimeter;

•

Install the pipe DN14 on the RENOVA ULTRA panel

realising the circuits as per the installation diagram;

•

Perform the leak test;

•

Evaluate and position the expansion joint strips according

to the UNI 1264 standard and/or according to the screed

manufacturer's instructions;

•

Proceed to pour the self-levelling compound in the

minimum thickness recommended by the manufacturer;

•

Carry out screed heating tests per UNI 1264 and/or as

indicated by the screed supplier.

•

Install the floor covering.

NOTE: For screeds, we recommend products with minimum

characteristics similar to those declared for the products used

in the tests carried out by Wavin Italia SpA such as, for example,

Knauf NE425, Kerakoll Keratech R30, Mapei Novoplan Maxi,

Laterlite PaRis SLIM.
