In the BNZ building, acoustic ceiling tiles were a convenient – and environmentally responsible – solution. Forman Building Systems has supplied its premium product, Armstrong Ultima ceiling tiles, for office ceilings throughout the building. The white tiles, in a non-standard 1350mm x 450mm size, are set into a conventional two-way exposed steel Amstrong Peak Form grid, capped with a white finish for a clean-lined look. With this particular grid, both the main and cross rails are exposed and, because of the shape of the tiles, they create a pattern of long, linear bands that run down the length of the office space. Ultima tiles have a high acoustic rating and a large recycled content; they offer excellent light-reflectant qualities and are impact-resistant, as well as carrying Good Environmental Choice Australia Certification. The Ultima tile is a life cycle-costed tile, designed to retain its quality and appearance for a long time. While there are other less expensive ceilings the client could have chosen, when working out life cycle costings, Ultima is one of the more economical tiles to use in these circumstances. To ensure the café and breakout areas have a calm and restful atmosphere, Forman Building Systems supplied Lindner acoustic metal ceiling tiles. The silver metallic appearance of these tiles complementing the retro look of the light fittings in these areas. In a further room noise reflection was important - Climateline powdercoated tiles were used in the 1350x450 size to complement the Armstrong Grid sizing.
