The precut EPS foam blocks are installed into the auditoriums after all the walls are constructed and the high work on the ceilings has been completed. Each of the EPS foam blocks come pre-numbered from the manufacturer corresponding to the Shop Drawings provided by SSE. SSE has developed several foam and steel composite designs that use simple straightforward materials and technology to meet today's criteria. The blocks are assembled according to the drawings and secured by means of a non-solvent based adhesive provided by the installing contractor. EPS foam is innovative!
