Earthwool® Pipe and Tank Insulation

Earthwool® Pipe and Tank Insulation

Knauf Insulation Earthwool® Pipe and Tank Insulation with ECOSE® Technology is a semi-rigid glass mineral wool board in roll form faced with a factory applied FSK or ASJ vapor retarder or a glass mat facing. The glass fibers are adhered perpendicular to the jacketing, for flexibility and easy installation.

ECOSE® Technology

ECOSE Technology is a revolutionary binder chemistry that enhances the sustainability of our products. The “binder” is the bond that holds our glass mineral wool product together and gives the product its shape and brown color. ECOSE Technology is a plant-based, sustainable chemistry that replaces the phenol/formaldehyde (PF) binder traditionally used in glass mineral wool products. Products using ECOSE technology are formaldehyde-free and have reduced global warming potential when compared to our products of the past.


Knauf Pipe and Tank Insulation with ECOSE Technology is typically used on tanks, vessels and large-diameter pipes. It can be used for any curved or irregular surfaces that require finished characteristics of rigid glass mineral wool insulation.
