Sonex™ Classic Colortec is the only acoustical foam offered by Sonex™ that is class 1 fire rated yet charcoal color throughout. Instead of simply painting the surface of white foam, like Sonex™ does with some of its other products, the Classic Colortec is actually dyed charcoal throughout the foam. This allows for a much improved visual appearance to the foam, since you do not have have any white showing through the paint or any white exposed where you may have had to trim or cut a panel down to size to fit your particular application. Sonex™ Classic Colortec features a modified enechoic wedge design for cost-effective yet impressive sound control.
