Construction Details
The Françoys-Bernier concert hall is a rectangular solid “shoebox” design with the concert platform fully within the volume of the room, no stage rigging or curtains.
The interior walls are concrete and grout filled dense concrete block. The masonry exposed in the audience chambers has been sandblasted to an extremely coarse finish.
The acoustic finishes:
- Main floor, the walls are lined with fireproofed 100% felt glued to a 19mm fireproof particle board installed 40mm from the concrete walls.
- Platform area, the rear of the platform is lined with pivoting panels, one side is lined with dense insulated panels covered with felt while the other side is finished with maple panels. The shell around the platform and on either side of the balcony level above the platform is lined with 19mm hardwood panels covered by quartered maple panels. The lighting and acoustic canopy above the platform is tilted at an 2.5° angle.
- Balcony level, the walls are lined with 3mm fireproofed felt glued directly onto the concrete.
- Technical ledge, the walls are lined with 13mm veneer panels installed 50mm from the concrete walls. 50% of this space is filled with insulation.
- Heavy curtains can be extended or retracted along the entire surface of the walls, at all three levels. The curtains nestle in curtain pockets when completely retracted. The curtains are 100% velour cotton, 25 once gauge and are completely lined.
- The underside of the balcony and technical ledge is lined 15mm wood panels. The ceiling of the hall is 25mm pyroc.
- The concrete floor has an glazed epoxy finish.
Mechanical and electrical rooms
These spaces are completely insulated from the audience and performance chamber in order to achieve the quality of silence that is needed in the Hall. The majority of the mechanical systems sit on neoprene cushions to avoid vibrations and noise that could be heard in the Hall.
All circulation into the audience chamber passes through sound and light locks.
HVAC, the audience chamber system is a series of conduits leading into a vast plenum under the seating area. The low velocity ventilation is carried from the mechanical system into the plenum up into the hall through diffusers placed under each seat or side walls.
