Polystyrene facades

A suit against 10 EIFS manufacturers, filed in North Carolina (New Hanover County) has achieved certified class action. EIFS are the (US) term for synthetic exterior wall cladding used to give insulation and exterior finish to building facades. Of stucco-like appearance, it basically consists of polystyrene. Unfortunately, when damp gets behind, it causes (at first unseen) damage to the building.
