If you mean Lead loaded vinyl, yes, I have used it on an industrial site to lower the noise through an office wall and it worked a treat. I also used it in my studio on the studio doors (recording room) as there was still a little too much sound getting through the doors, I stapled a sheet of lead vinyl onto the inside of the doors and it was like adding another whole door in noise reduction.
One word of warning, don't forget that the lead vinyl is very heavy, what ever you put it on must be able to handle the extra weight load. Where are you thinking of using it?
