Armstrong World Industries has launched a new micro-site to help specifiers choose the best acoustical solution for their projects. This web site enables visitors to easily compare the product specifications of Armstrong’s complete acoustical range — including mineral wool, wood and metal tiles. There are full details on i-ceilings sound panels, an invisible in-ceiling speaker system designed to improve audibility in schools. Among useful selection tools is a reverberation simulator to compare the different reverberation times of various tiles to help specifiers make the best chose for their desired sound quality. Case studies are also featured.
