INSULATING SEAWEED

Seaweed is a fibrous, malleable and plentiful material and was often used for wall insulation by the Ancient Greeks. Structures would be built using sun-dried clay bricks or a wooden frame which would be filled with seaweed or straw and covered with clay or plaster.

Seaweed is used in traditional Danish architecture, as roof and ceiling insulation. Unlike a number of conventional building materials, it is non-toxic and it’s tightly packed cellular makeup means it is also fireproof. A material with a long life expectancy, seaweed also possesses antibacterial compounds, and effectively absorbs moisture, resulting in a healthy indoor microclimate and will help a building keep a constant temperature throughout the seasons.
