AGI AG für Isolierungen

Dällikon insulation and technical-services firm holding 24 live VKF recognitions, every one in Untergruppe 223 Abschottungen/Durchführungen, with numbers running from the 111xx series to the 128xx block. It is the only Swiss contractor rather than product manufacturer to hold a double-figure firestopping holding in its own name — in a register with no applicator scheme, that is the closest thing Switzerland has to certified firestopping workmanship.
