Strawbales are an excellent insulation material and because of their density, are also excellent thermal mass. They are also a rapidly renewable resource. Up to this point, however, they have been on the fringes of building technology because of the time it takes to build with the material. ModCell has come up with a viable way to turn stawbales into super-insulated building panels for commercial and residential use. They claim that these panels are zero carbon or better to create, which is infinitely better than rigid insulation can even think to claim. Brilliant!
