ISO Blanket and ISO Blanket Pro are limp-mass solutions designed for the treatment of airborne noise. They differ in their STC (Sound Transmission Coefficient) in that ISO Blanket Pro has a bigger coefficient/performance due to its agglomerated fabrics.

The blankets perform as sound barriers when applied to ceilings, walls and floors. Their flexibility, thin design and high resistance make them easy-to-use materials. They are most effective when used in construction projects that involve several layers of different material.
