Sonex Super is designed in wedges for applications where maximum sound absorption is needed. The Sonex Super foam is generally used in creating anechoic rooms for testing facilities. It is offered in two versions, the standard being a Willtec foam (#OSN-6) which is Class 1 Fire Rated and 100% fiber free. This foam is white or light grey, but there is an option to have the surface painted (#OSNP-6) in charcoal, beige, brown, blue or light gray. The second version of Sonex Super is a polyurethane foam (#SS-6), which is more economical, but not Class 1 Fire Rated. The standard colors for the polyurethane foam are charcoal, beige and brown.
