The Swiss operating company of the Hilti group, headquartered across the border at Schaan in Liechtenstein, holding 45 live VKF recognitions — 42 in Untergruppe 223 Abschottungen/Durchführungen and three in 224 Fugenabdichtungen. That is the largest firestopping holding in the Swiss register by a wide margin, covering collars, wraps, cushions, blocks, boards, coatings, mortars, sleeves and cable transits as separately approved systems rather than one blanket approval.
