Sprinter Interior What Is That Gray Plastic Paneling That Is Used On The Interiors Of Sprinter Vans And Where Can I Get Some?

What is that gray plastic paneling that is used on the interiors of sprinter vans and where can i get some? - sprinter interior

I perform an update of my E-150. after spraying foam insulation on some of those who want to cover headline and some for later. I admired my friends and nice Sprinter gray panels used to cover the walls of the hold on. It is a corrugated plastic. Does anyone know the manufacturer of the material and where the Mid-Atlantic region, we would get ourselves a little?
Thank you,
