Giacomini’s radiant systems equip more than 1200 homes in the Athlete’s Village with a superb acoustic performance radiant floor and its 90% recycled screed.
Thanks to its expertise in radiant floor heating, Giacomini has been chosen to provide comfort to the best athletes in the world. Giacomini’s radiant systems cover a total of 130,000 m² of the new Athlete’s Village of Paris.
In this large-scale project spanning three municipalities (Saint-Ouen-sur-Seine, Saint-Denis, L'île-Saint-Denis) around Paris, Giacomini now equips more than 1200 homes.
Initially, Giacomini was chosen by Eiffage Immobilier, responsible for block E of the athletes' site. This parcel of the site covers an area of 47,000 m² and 527 homes. Thanks to the performance of its floor heating, Giacomini’s radiant systems was later also chosen through the tenders to equip additional apartments in neighboring blocks (A1, A2, B2, and sector D); adding 673 additional homes.
Exceptional acoustic performance
The reversible floor heating solution used in the different blocks uses a special insulating panel which integrates the 30 mm flat rock wool.
The system was selected particularly for its excellent acoustic performance of 28 dB and its low-carbon screed (performance tested by CSTB, the French national organization for research in the construction industry).
A total floor thickness of only 66 mm excluding floor covering
The reversible radiant floor solution from Giacomini is implemented in the units intended to be connected to the urban heating network (mainly powered by geothermal energy) in the Pleyel district of Saint-Denis.
Each apartment is equipped with a distribution manifold for the loops with the manufacturer's R206A regulation and balancing valve. The reversible floor consists of the 30 mm thick rock wool insulating panel on which the PE-RT (Ø 16 mm) pipes are installed.
These pipes offer an integrated oxygen barrier to limit the clogging of hydraulic networks. The pipes are fixed to the insulation with a spacing of 20 cm and then covered with a 36 mm thick anhydrite fluid screed, for a total floor thickness of only 66 mm excluding the floor covering.
A recycled and recyclable low-inertia screed
Beyond the acoustic performance of the Giacomini system, the building company Matos IDF also met the demanding specifications of this low-carbon site, thanks to its Thermio Max anhydrite screed, recyclable and composed of 90% recycled raw materials.
The floor covering is compliant with the French building regulation CTP3164. The screed is designed to receive an acoustic underlay above which a laminated floor will be installed.
Moreover, the reduced thickness of the screed (20 mm above the pipe) offers very low thermal inertia, less than one hour.
Finally, each apartment is equipped with a K480PY301 room thermostat connected to the manifold, responsible for executing its commands and managing the network balance for perfect homogeneity of the heat or coolness distributed by the floor.
Performance: a maximum power output of 50W/m²
The floor is laid at a rate of approximately 600 m² each week by a team of three people from the specialized installation company A.C. Zamparo.
Each of the loops that make up the hydraulic network of the floor starts and returns to the manifold and is fixed to the insulation without any joints. Once installed, the network is tested before the screed is poured. The pipes are subjected to twice the operating pressure to check their resistance and the total absence of leaks.
Once operational, Giacomini’s radiant floor provides a maximum power output of about 50W/m² in heating mode for a set room temperature of 19°C and about 30W/m² for cooling set at 26°C.
