As Reglazing Modernism: Intervention Strategies for 20th-Century Icons celebrates its third year in print, it is still being heralded as the definitive book on interventions to steel-framed glazing assemblies in Modern buildings.
Featured in its latest newsletter, Docomomo_US recently published an excerpt of the book, one that focuses on interventions at the UNESCO World Heritage Site Zeche Zollverein. This Bauhaus-influenced mine complex (1927–1932) and coking plant (1961) in Essen, Germany, was designed and built to improve the system of coal extraction and processing. Interventions over the decades since the mine and plant concluded operations in 1986 and 1993, respectively, included the following:
Simply restoring the steel profiles with the existing single-glazed panes or with new wired glass panes (Halls 2 and 5)
Adding new slim IGUs partly with wired glass panes (Hall 7)
Installing a thermally broken frame with IGUs with wired glass (Hall 9)
Installing insulated partitions with secondary glazing consisting of single-pane steel frame casement windows set within an interior insulated partition built parallel to the existing exterior walls, thereby creating a large insulating air cavity (Halls 6 and 10).
Co-authored by Principal Angel Ayón, Reglazing Modernism was awarded the 2021 Lee Nelson Book Award from the Association for Preservation Technology International (APT), The book — recognized for being the most outstanding and influential book-length work on preservation technology in three years — was published in 2019, followed by a private book signing and launch celebration in February 2020 at the TWA Lounge at One World Trade Center in New York City.
