Sonex™ Junior acoustical foam from Illbruck is the same pattern as their 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 #SJ2) which is class 1 fire rated and 100% fiber-free.
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..
