System-Level Conditions Shaping the Deployment of Wood Fibre Insulation in European Residential Construction

Abstract

This study examines the deployment of wood fibre insulation (WFI) in residential construction through a comparative system-level analysis of Finland, Germany, and the United Kingdom. It explores how regulatory frameworks, construction systems, housing structures, and broader industrial contexts jointly shape the feasible application of WFI. The analysis combines documentary sources with expert insights to identify key structural conditions influencing WFI deployment.
The results show that WFI deployment is primarily constrained by the alignment of regulatory requirements and dominant construction systems, particularly regarding building height and fire safety classifications. Although low-rise construction offers more permissive conditions, established masonry and concrete-based practices limit broader adoption. Overall, the study demonstrates that WFI deployment is shaped by the interaction of multiple structural conditions and contributes to the literature by providing a comparative system-level perspective on the adoption of bio-based insulation materials.
