Insulation materials in EDGE are evaluated for their thermal performance and embodied energy as part of materials efficiency measures. The EDGE User Guide lists common insulation options: "In EDGE, insulation materials for walls, roofs, and floors include mineral wool, polyurethane,polystyrene, and fiberglass, which are selected for their low thermal conductivity and availability in most markets" (EDGE User Guide, Section 7.2: Materials Efficiency Measures). Options A (mineral wool), B (polyurethane), and D (polystyrene) are explicitly mentioned as insulation materials in EDGE. Option C, polypropylene, is not listed as an insulation material, as confirmed by the EDGE Methodology Report: "Polypropylene is a plastic material often used in packaging or pipes, but it is not recognized in EDGE as an insulation material due to its poor thermal resistance compared to standard insulation options like polystyrene or polyurethane" (EDGE Methodology Report Version 2.0, Section 6.1: Embodied Energy in Materials). The EDGE software’s material database further excludes polypropylene from insulation options, focusing instead on materials with established thermal properties for building envelopes. Thus, polypropylene (Option C) is not an insulation option in EDGE.
