In response to the aesthetics demands of the high-end residential market and a trend for industrial styling by architects, Waterloo Air Products has devised a specialist range of grilles and diffusers. There are three types of product. Plasterline linear grilles can, as the name suggests and the picture makes clear, be integrated into a building’s design. Linear diffusers are offered with a huge range of finishes and colours, including special effects such as various woods, carbon fibre, animal prints, leather and marbles. Finally, the Urban Grille is designed for projects where exposed ductwork is a feature of a building’s design.
