Made from recycled PET bottles, the lightweight bricks offer excellent acoustic and thermal insulation and can build anything from fences and roofs to pots for plants, skylights and beautiful walls of light… POLLI-Bricks possess incredible thermal and sound insulating characteristics in addition to an awesome strength to weight ratio, which should make them a hit with architects and builders alike. While you can’t yet get these at your local building supply mega-store, the economy, versatility and structural potential of the POLLI-Brick may just be what a struggling building market needs.
Cool product and, as usual, this would be a better open-source hardware project. Any suggestions for copying this in a DIY way?
