Internationalization of activities began with the acquisition of Julien Redois S.A. and Soferba S.A. in France - now Novoferm France S.A. - and foundation of Novoferm Espana S.A. in 1991. Isselwerke GmbH & Co. KG was renamed into "Novoferm GmbH" one year later. Furthermore, shares of the Dutch manufacturer of industrial doors Debo Holding B.V. were acquired in 1992, and sales companies in the Netherlands, Poland, Hungary and Switzerland were set up.
Step by step Siebau Siegener Stahlbauten GmbH and Riexinger Türenwerke GmbH also became members of Novoferm as from 1993. With Novoferm Belgium N.V. a sales subsidiary in Belgium was established (1994), and so was a sales company for industrial doors in France (1996). The Italian door producer Schievano S.r.l. was also acquired in 1996, a sales subsidiary was built up in Greece and Novoferm entered into a joint venture with Novoferm Alsal S.A. in Spain. Sales companies in Great Britain, Romania and the Czech Republic opened in the following year. Moreover, a French producer of fire-resistant doors, Lutermax S.A., was acquired. One year later, a most up-to-date European plant for sectional doors was ceremonially opened in Dortmund. Novoferm took a 50 % share in the Dong Bang Steel Door Inc., South Korea, in 2000, and acquired the operator manufacturer tormatic GmbH in 2001.
