Sonex™ Junior Acoustical Foam

Sonex™ Junior is the same pattern as our famous Sonex™ Classic panels except that the panel size is smaller (2X2 instead of 2X4) and the number of panels packaged in a box is fewer also. It is offered in two versions, the standard being a Willtec foam (part #SJO2) which is class 1 fire rated and 100% fiber-free. The color is white, but there is an option to have the surface painted (part #SJO-2P) in charcoal, beige, brown or blue. The second version of the Sonex™ Junior is a polyurethane (part #SJN-2) which is more economical, however that is not class 1 fire rated. Standard color for the Polyurethane version is charcoal, beige or brown.
