Whether the insulation task involves heat, light, sound, moisture or gases, aluminium foil is a high performance material. Its highly reflective surface has, for example, earned it an indispensable place inthe insulation of domestic, commercial and industrial buildings. In ducting and pipework too, where the suppression of heat loss or gain is essential, alufoil’s reflective (up to 98% of light and infrared heat) and barrier properties make it the material of choice.
In electrical cables, aluminium foil is an essential component providing long-term protection. It also insulates against magnetic and radio frequency emissions. Used in fibre-optic cables, aluminium foil acts as a ‘tracer’ to enable testing of the integrity of cable links.
