The natural process of sound vibration creates friction and unwanted energy buildup through the bending and slipping of adjacent surfaces. This in turn causes the floor to add unwanted acoustic coloration to your room. The IsoDeck isolates the floor, using a unique high density 1” felt strip called a slot loaded spring, inserted into the bottom of every joist to float the deck. The felt is lightly glued into a 3/4” x 3/16” rabbeted groove.
The top of each joist is covered with strips of damping polymer called WallDamp. Two layers of subfloor rest on the joists, separated by squares of WallDamp. With this system, even high power sub-bass energy is isolated and rapidly dissipated. You get real sound isolation, reduced floor resonance, and damping even when there’s thunderous sound.
