Sustainable biobased building envelopes

This project aims to substitute fossil-based insulation in the building envelopes with bio-based alternatives, by reducing uncertainties in implementation. Moving away from well-proven and accepted technical solutions in the construction sector poses a risk, especially since mistakes can take a long time to detect. In industrial construction, the same type of solution is reused in many objects and any problems that arise during the use phase are therefore likely systematic and difficult to handle.

For this reason, uncertainties linked to new technical solutions (energy, moisture, fire, acoustics, durability) need to be analysed at a higher level before it becomes rational to deviate from a well-proven and established solution.

The project brings together researchers and several important actors and a large part of the Swedish wood house industry with the ambition to map the state of knowledge, and solve a number of technical and practical challenges, as well as investigate risks during the use phase linked to bio-based insulation.

Budget & time plan

The project’s total budget is 8,4 SEK and the project runs during 2,5 years – between November 2022 and April 2024.
