Portable Foam Panel Log Cabins LLC would like to introduce to you building portable modular housing with ( SIPS ), Structural Insulated Panels. These panels are glued and laminated together with expanded polystyrene and are sandwiched with steel on steel snap lock panels. They are full livable with all the comforts of a larger home and can be occupied the day of delivery. SIP panels have been proven to be up to 58% more energy efficient than stick build construction because of the great insulation values of polystyrene. This structure gives an ice chest affect.
