DIME Tiles are cut from class A fire rated melamine foam, which produces twice the absorption coefficients typically found with standard commercial grade ceiling tiles. DIME Tiles are a hybrid product of a 1" thick melamine foam panel adhered to a 1" thick fiberboard designed to give the tile rigidity and prevent shrinkage. Bevel patterns in the tiles are designed to produce a unique visual presentation to your space, or the tiles are available as a plain smooth surface finish.
