Mineral Wool Pipe & Tank Insulation

Mineral Wool 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 a variety of jacketing. GLT Products mineral wool jacketing is also available with an ASJ or FSK facing. The orientation of the mineral wool fibers gives the material the characteristics of a rigid board. Mineral Pipe and Tank Insulation can be applied with staples, mastic, tape or other mechanical fasteners. Available in 36˝ widths and thicknesses from 1˝ to 4˝.

GLT Products Mineral Wool Pipe and Tank Insulation eliminate the need for stocking large diameter pipe insulation, thereby eliminating job returns of the slow-moving items.
