Insights from Finnish Experts on the Construction Practices and Future Prospects of Cross-Laminated Timber (CLT)
Abstract
Given that CLT is a relatively recent innovation, there is a notable scarcity of market research in Finland. Presently, there is a limited body of literature that provides a thorough comprehension of the present state, varied applications, and anticipated future developments concerning the use of CLT within the Finnish construction sector. The limited availability of research data underscores the need for more extensive studies to fill this knowledge gap and provide a more nuanced insight into the evolving landscape of CLT adoption within the Finnish construction industry. This article aims to fill this gap through semi-structured, in-depth interviews with 15 Finnish experts. Key findings highlighted that (1) the hierarchical order of familiarity with CLT among construction professionals in Finland, ranging from highest to lowest, was identified as follows: architects, engineers, developers, builders, and contractors; (2) a pronounced necessity exists for heightened expertise and training within the realm of CLT; (3) CLT was considered a promising option in endeavors aimed at mitigating the impacts of climate crises; (4) CLT showcased adaptability to environments marked by highly fluctuating climatic conditions, emphasizing the importance of a comprehensive approach, including proactive maintenance strategies; (5) Finland adopted commendable and forward-looking sustainable practices in forest management; (6) the adaptability of CLT across a wide range of building categories; (7) the perceived vulnerabilities in CLT construction primarily included a lack of cost-competitiveness, insufficient sound insulation, and inadequate production volume; and (8) key future market prospects encompassed the versatility of CLT, increasing demand propelled by environmental considerations, and collaborative advancements in hybrid construction techniques. This article will contribute to the greater usage of CLT in the building industry in Finland by revealing the challenges, potential, and future outlook of CLT use.
