Frequently asked questions
Which is the largest employer in Manufacture of other non-metallic mineral products in Liège province?
Among companies, Knauf Insulation, with 445.3 full-time equivalents reported (financial year 2025).
Are all the jobs located in the area?
Not necessarily: headcount is reported by the company for all its sites, and the company is ranked by the address of its registered office. 81 out of 120 companies in the sector report employees there.
Why does this ranking differ from other lists?
