4. Residential systems

General information

The category of Residential Systems includes all traditional

underfloor radiant systems with traditional 45-mm sand and

cement screeds or calcium sulphate-based self-levelling

screeds with a minimum thickness of 30 mm. Therefore, these

are systems with standard thermal inertia.

Preliminary precautions

The traditional systems are all designed to realise floating floors;

in this way, 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.

It is recommended that:

These are the traditional systems for which the UNI EN 1264

•

standard was, in fact, written. Therefore, by following the

directions, in particular those described in Part 4 dedicated to

installation, one will obtain a proper system.

These systems can be realised with many different products,

especially in terms of panels and pipes.

•

They can be distinguished by the type of panel used:

•

Flat panels: greater thermal output;

•

Knob panels: greater ease of installation;

The bearing area be dry. Especially in the case of a cellular

cement screed, it is important that water in the screed be

evaporated before proceeding to the installation of the

radiant system. Otherwise, the structures are likely to retain

moisture for a long time, with possible degradation of the

materials of the structures themselves;

The bearing area is flat. A screed of radiant floor covering

of variable thickness leads to different response times, as

well as increased cost, particularly in the case of a self-

levelling screed.
