I did a fair amount of research regarding Ceiling Tiles ( and Drop Ceilings ), what I discovered was that your Styrofoam Glue-up was: 1. EASY (DIY) to apply; 2. Virtually IDENTICAL in appearance to High Dollar 'plaster type' tiles; 3. VERY affordable if not LESS costly than alternatives ( Drywall Popcorn/Plasters ); 4. VERY 'forgiving' with regard to placement/alignment/re-alignment and 'caulking' seams ( easy ).
