Campus Institut Mines Télécom

After several attempts to improve ductwork airtightness and after airtightness testing through a certified expert (QUALIBAT 8721), an average leakage rate of airtightness class A was determined. At the beginning of the Aeroseal project, the entire ductwork was installed and already connected to the laminar flow ceilings. In most of the laboratories, the metal substructure for the suspended ceilings was already installed. Against this background, the plant manufacturer contacted Sogestfa for an additional sealing with Aeroseal, in order to achieve an airtightness class C, that was required according to the thermal calculation.

PROJECT

Building: Campus Institut Mines Télécom Sud
City: Paris/France
Date: 11 May 2016
AEROSEAL Partner: Sogestfa
Target: Achievement of airtightness class C
Preseal leakage: 139.6 l/s
Postseal leakage: 4.3 l/s
Reduction of leakage: 96.9%

PROJECT COURSE

In only one day, including preparation, sealing and return to service, an air duct system was sealed with Aeroseal. The ductwork was mainly rectangular, with some circular sections. The plenums of the filter ceilings were already installed. Thanks to the Aeroseal process, it wasn't necessary to dismantle the partitioning of the riser ducts or the metal substructure for the suspended ceilings. The Aeroseal project didn't cause any additional delay on the building site's timetable nor affect the other trades' work in a negative way. The cost of the sealing with Aeroseal was well below the cost for a traditional approach.

CUSTOMER QUOTE

The customer Institut Mines Telecom was very pleased with the achievement of the tendered airtightness class C, necessary to comply with the thermal calculation.
