Ziegler Group starts wood fibre insulation board production with new Dieffenbacher plant

Production of the first board on Ziegler Group’s new Dieffenbacher WFIB plant in Grafenwöhr, Bavaria, Germany on 30 Aug 2022

A complete wood fibre insulation board (WFIB) plant provided by Dieffenbacher for Ziegler Group’s site in Grafenwöhr, Bavaria, Germany, is up and running less than one year after construction began.

According to Dieffenbacher, the line for rigid WFIB began production on 30 Aug 2022. Ziegler Group placed its order with Dieffenbacher on 1 Apr 2021, but the construction only began five months later on 1 Sep 2021 due to a change of location from the town of Bärnau, 50km west to Grafenwöhr, on a short notice.

“We are very pleased that our new Dieffenbacher WFIB plant had such a rapid and successful start,” said Andreas Sandner, commercial managing director at Ziegler Group.

Dieffenbacher’s scope of supply for the complete plant included a fibre dryer, EVOjet M 2.0 gluing system, the forming station and forming line with pre-press, a CSS continuous steam press system, the raw board handling system, electrics and automation and the MyDIEFFENBACHER digital service platform.

“We never would have been able to achieve this record-breaking construction and completion time without the full cooperation of our partners. In this case, especially Dieffenbacher,” said Sandner.

“The change of location and the procurement crisis during the pandemic made this feat all the more remarkable. Our thanks go to the entire Dieffenbacher team, which overcame huge challenges to meet our requirements for product quality and energy efficiency.”

In addition to the WFIB plant just completed, Ziegler Group commissioned Dieffenbacher to supply another fibre dryer for flexible insulation mat production at the Grafenwöhr site. Construction began in June, and the 10-tonne-per-hour capacity dryer is scheduled to go into operation in October.
