Problems with Styrofoam Insulation | Homesteady
Polystyrene insulation in the form of small beads, meant for pouring into hollow wall cavities and concrete blocks, has a very high mobility. According to the US Department of Energy, it is extremely lightweight and acquires a static charge easily, making the beads hard to control. These beads may fly out of blocks or cavities when exposed to wind, may stick to surfaces when charged with static electricity and can pour out of crevices in a wall. Some builders mix these beads with concrete or other materials to keep them in place.
