The way "Stretched-Fabric Wall System" works is a three part process using a Fabric mounting track/frame, acoustical or tackable core material and the covering fabric... 

First, the track is attached to the wall around the perimeter of the area to be covered. Based on the fabric width, panels can be up to 5 1/2 feet by the length you desire. The layout therefore, does not require joints every 4 feet as traditional pre-made panels. After the track is installed, the core material is then in-filled inside the tracked perimeter. The last step is rolling the fabric into the track's locking jaws. The fabric is stretched over the substrate or core material and is pulled taut as not to sag or slip over time.
