Industrial insulation is designed to control heat transfer, improve energy efficiency, protect personnel, and support reliable plant operation. However, insulation materials also need protection from moisture, weather, physical impact, chemicals, and everyday maintenance activity.
This is where aluminium jacketing becomes important.
An aluminium jacketing sheet forms the external protective layer around insulated pipes, tanks, vessels, ducts, and equipment. It does not replace the insulation itself. Instead, it helps protect the insulation so the complete insulation jacketing system can continue performing as intended.
