The barrier properties and heat reflectivity of aluminium foil are widely used to improve insulation performance of modern building systems.
Aluminium foil is used
Aluminium is ductile. Foil can be rolled to only 0.007 mm thickness, but will still be completely impermeable and lets neither light, aroma nor taste substances in or out. The metal itself forms a protective oxide coating and is highly corrosion resistant. Different types of surface treatment can further improve these properties.
