PapeRock is a non-toxic, incredibly strong composite building material made from layer upon layer of paper (recycled or from sustainable sources) and bonded with phenolic resin. The material is then heat/pressure cured. The material is workable by any trained carpenter with normal wood working tools. PapeRock is impervious to water, heat resistant up to 180 degrees and is so strong that a 20 mm benchtop can be cantilevered to 460 mm.
