Mechanically Attached Single-Ply / Steel Deck

Single-Ply foam board can be mechanically attached to steel-deck roofs, but solvent-based membrand adhesives and dark color membranes require a cover board, such as 1/2" wood fiber, between the insulation and the membrane. A light-color, chemically compatible membrane can be applied directly to polystyrene insulation.
