LIGHTWEIGHT， WEATHER-RESISTANT， BARRIERS， METHODS AND STRUCTURES USING THE SAME

Insulated building products， methods and structure using those products are disclosed. The embodiments described include building materials having a core of encapsulated polystyrene (EPS) which is completely coated with a polymer. The polymer coating provides protection and structural integrity to the foam such that virtually indestructible structures can made of EPS foam that can form barriers for use in crowd control， cordoning off areas， creating corrals for lines at events， etc. Moreover， additional embodiments are provided in which additional structural integrity is provided by affixing one or more rigid materials to the EPS foam prior to coating. The results， as disclosed， are light-weight， portable building structures that can be made into lightweight， easily deployable and easily storable barriers.
