ADO Pac fabric is ideal for knee walls, ceilings, sound walls and many other applications. Keep your job site dust levels down to a minimum. Our best value, high quality non-woven is made of 100% polypropylene, point bonded material. The 8' 4", 9' 2" and 10' 2" wide rolls are folded for greater convenience when moving quickly through the job site installation. ADO Pac is not the preferred fabric for wet/damp spray installations - See line of ADO Web SKUs for this application.
