Timber door factory at Brunegg trading as Brunex, holding 87 live VKF recognitions — 59 of them in Untergruppe 241 Brandschutztüren, the single largest concentration in that family in the register, plus 27 glazed fire doorsets and one glazing approval. Unlike the metal-construction holders it is a specialist in timber leaf and frame construction, which is what makes it the reference supplier for Swiss joiners fitting rated internal doorsets.
