Impact
Reduced thickness
Up to 5× thinner than conventional insulation — freeing pipe routing space and reducing material volume on site.
Lower heat loss
Superior thermal conductivity minimizes energy loss, lowering operating costs and improving process stability.
Reduced maintenance
Hydrophobic, corrosion-resistant performance reduces Corrosion Under Insulation (CUI) and re-work frequency.
Faster installation
Flexible blanket form is faster to handle and fit around complex geometries, shortening shutdown windows.
Lower lifecycle cost
Long service life and lower energy & maintenance load deliver a lower total cost of ownership over time.
Pricing varies depending on specification, thickness, operating temperature, project quantity, cladding systems, installation scope and industry application.
