How does the STClip work? 

After being placed between the steel studs, the sound waves become trapped. Sound can travel through any solid surface, but it also can be contained in a space. The STClip takes in that sound and absorbs it, so that the sound will not continue to travel through the wall. Its design allows for thinner walls, making floor space larger and reduces costs. The duel layers make it more effective and squash the time it takes to install. Walls with the STClip had higher STC ratings than traditional walls with resilient channels because of the innovative design and product.
