Neptune Balls

While sitting on the beach, trying to light a campfire covered with fibrous droplets, and not having any luck, Richard Meier, an American architect, wondered why the fire would not light? Upon further investigation, he realized it was extremely difficult to put fire to these strange fibrous globs that were lying around all over the beach, and this gave him the idea that would become NeptuTherm.

Instead of using materials like aluminium and polyester as roofs and walls insulator, NeptuTherm has developed a way of using a by-product of the sea, also known as Neptune balls, for insulation. Although written in Dutch, the photographs on this webpage clearly demonstrates how to lay this amazing material between the roof panels for insulation.
