New Mussel Shell Material Promises to Prevent Moss on Roofs

Thanks to a collaboration with material research scientists at Bangor University’s BioComposites Centre, Pennotec has put their discovery of mussel shells’ ability to bind and release copper to improve the built environment.

Gradual release of copper from Pennotec’s mussel shell-based composite material prevents the growth of green algae that cause unsightly staining of building surfaces. The product will also prevent the growth of lichen and moss on roofs and slime on wet surfaces, massively reducing the cost of home maintenance.
