When the government of Canada asked for granite floors, glass guardrails, metal trim and wood ceilings in the lobby of the LEED® gold James Michael Flaherty Building at 90 Elgin Street, Ottawa, we knew that the space could appear elegant and beautiful, but that acoustics might be an issue. There was concern that excessive reverberation caused by the use of hard surfaces would make it very difficult to hear any announcements over the public address system. The careful selection of ceiling materials offered the opportunity to improve the acoustic performance. Click here for an article by the ceiling manufacturer on their materials employed at the Flaherty Building.
