What is the difference between AlphaFlat Foam and Sonex Willtec Flat Foam?

AlphaFlat and Sonex Willtec Flat foams are made from a similar melamine acoustical core with equivalent acoustical properties.  AlphaFlat is available in a range of thicknesses from 1″ to 4″ with a standard sheet size of 2’x4′, where as the Sonex Willtec is available in thicknesses of 1/2″ to 2″ with standard sheet sizes of  2’x2′, 2’x4′, 4’x4′, and 4’x8′.  The AlphaFlat foam has a similar color selection, but the grey color is slightly darker than than that of the Sonex Willtec and the AlphaFlat offers a charcoal color. If a cleanable, durable surface is required, Sonex Willtec may be custom coated with HPC coatings. If necessary, either of these two products may be ordered in custom sizes and configurations for OEM applications or special projects.
