Biobased insulation materials such as hemp, flax and cattail can lower building energy demand while also storing carbon in the material. This means insulation works not only in the use phase of homes, but also in the material impact of construction and renovation.
The source makes biobased insulation relevant for climate, agriculture and health. Local crops can create new value chains, while better insulation improves comfort, sound reduction and indoor climate. The strongest value emerges when material choice, renovation planning and energy performance are considered together.
