LA HALLE DE PANTIN

La Halle de Pantin, FRANCE
Architect: Norbert Brail

DS Smith Plastics

“La Halle de Pantin”, or Pantin Hall built in 1942, is the largest commercial hall dedicated to the building market in France which will house under one roof eight brands spanning the entire range of building materials: POINT.P Matériaux de Construction, La Plateforme du Bâtiment, CEDEO, Décocéram, PUM Plastiques, CDL Elec, Outiz and SFIC. The building is characterized by its high energy performance and perfect airtightness. That could be achieved by using PC sheets for the skylight openings. The energetic consumption of the hall is kept on a level of 77 kW of primary energy/m² per year which is much less than the minimum required by the French Thermal Regulation (RT 2012). The aim of Norbert Brail, the architect who worked on this renovation project of 35 000 m², was to refurbish the three juxtaposed parts of the roofing composed of inclined sections of glazed skylights by using a minimum of pillars and supports while reusing the exisiting concrete structure in order to help improve the flow of traffic inside the building. Another objective was to allow a maximum of sunlight into the building. The use of PC sheets allowed for optimal light transmission without producing a dazzling effect which could occur had glass canopies been used. Cellular polycarbonate was used for the roofing and cladding. A total of 1000 m² of wired glass was replaced with polycarbonate translucent panels equpped with a clip system which were fixed to the already existing concrete structure to which steel supports were attached. Thanks to the high thermal insulation properties of the PC sheets used in this project and therefore excellent airtightness the heat losses of the polycarbonate part of the building are extremely low. The installation company that worked on “La Halle de Pantin“ is certified as “responsible in eco lighting” by OPUS LIGHT in Paris.
