Graphene is an astonishing material that is both flexible and stronger than steel. The Graphene Company have utilized its powers to create an eco-friendly paint which is also long-lasting – ‘Graphenstone’. It is superconductive so acts as an insulator meaning you can switch off the central heating and air-con, helping both your pocket and the environment. Plus, a little goes a long way, as only one liter of paint is needed to cover eight square meters twice.
