Mineral Wool Pipe and Tank Insulation

Pipe and Tank Insulation is a semi-rigid mineral wool designed to insulate large piping (over 8" IPS), and other curved surfaces. It is made with the fibers perpendicular to the surface and comes with various jackets. The orientation of the fibers gives the material the characteristics of a rigid board.
