Abstract
The present disclosure describes use of filamentous algae to form insulating construction materials which provide thermal and noise insulation. Algae from the order Zygnematales, the Cladophorales, or the Ulotrichales can be dried and formed for use as insulating material. Algae mass can be combined into several layers, using a binder to attach the layers to each other. A composite material of algae mass and an additive can be used and form the body of insulation panels having honeycomb-shaped chambers, which are sealed by a foil that is laminated onto the body.
Claims10
A construction material made of algae, comprising:
- a first layer of filamentous string-shaped algae having a first predominant orientation and
- a second layer of filamentous string-shaped algae having a second predominant orientation,
- wherein the first layer and the second layer are connected to each other by a binder and arranged such that the first predominant orientation and the second predominant orientation are non-parallel.
A method for producing for a construction material made of algae, comprising:
- harvesting algae;
- drying the algae to form a dried algae mass;
- placing the dried algae mass into a sealed container, the algae mass being held by mounting fixtures at both ends of the sealed container;
- holding the algae mass under tension by the mounting fixtures;
- heating and evacuating the sealed container;
- allowing the algae mass to carbonize;
- and
- removing carbonized algae material from the container.
