Sonex™ Classic Colortec Acoustical Foam is the only acoustical foam offered by Sonex™ that is Class 1 Fire Rated yet colored throughout. Instead of simply painting the surface of the white foam like Sonex™ does with some of the other foams, Classic Colortec is actually dyed throughout. This allows for a much improved visual appearance to the foam since there is no white showing through paint or even any white exposed on the sides and cut edges. Sonex™ Classic Colortec features a modified anechoic wedge design for cost-effective and impressive sound control.
