The project ran between November 2022 and September 2025.
Durable Biobased Building Envelopes aimed to accelerate the transition from conventional, fossil-based insulation to bio-based alternatives in industrially produced timber houses. The project brought together LTH, RISE, TMF and nine Swedish timber-house manufacturers to reduce technical and practical uncertainties related to energy performance, moisture safety, fire, acoustics and durability. Work included mapping available materials and reference projects, defining performance requirements, modelling and validating hygrothermal behaviour, and developing decision support for implementation. By combining research, industry experience and pilot-scale evaluation, the project has strengthened the knowledge base for robust, cost-effective and climate-smart bio-based wall solutions suitable for industrial production.
