Aluminium insulation and cable foil

Key features

• Aluminium foil is used as a skin for heat-insulating and incombustible materials to provide high performance insulation for pipe work and ducting.
• The adhesive tape used to secure the laminated material is based on aluminium foil or its reflective surface, corrosion-resistance and long life.
• In electrical cables, aluminium foil helps give long-term insulation against moisture and attack from naturally occurring corrosive elements found above and below ground.
• Aluminium foil also acts as an insulator against the magnetic and radio frequency emissions associated with electrical cables.
• As a sheath for fiber-optic cables, aluminium foil uses its electrical conductivity to act as a “tracer” to enable testing of the integrity of cable links – as well as helping to provide the long-term protection every cable needs.
• In fire walls for vehicles and fireproof doors and building panels, aluminium foil stops access to the oxygen required to support flames.
