The only DuPont recommended specialist material needed for use with DuPont™ Energain® panels is DuPont™ Energain® aluminium tape. When cutting the panel, it shall be used to tape any 'open' edges, where the internal compound of the panel would otherwise be exposed. DuPont™ Energain® aluminium tape shall also be used to repair any abrasions or damages to a panel's aluminium surface.
