biw Isolierstoffe GmbH
biw Isolierstoffe GmbH is a Private limited company (Ltd.) registered in Germany under HRB 5626 Hagen, and its current status with Handelsregister (Commercial Register) is active. Its registered address on file is Ennepetal, Germany. 1 shareholder is on record for biw Isolierstoffe GmbH, and since every one of them is a company rather than an individual, this particular filing does not on its own establish an ultimate beneficial owner (UBO) — identifying one would mean tracing the ownership of each shareholding company in turn. This profile is sourced directly from Handelsregister (Commercial Register) and was last updated on 2 October 2026.
