While PU has higher upfront costs (typically 20-50% more than EPS/XPS), its superior R-value means less material is needed to achieve the same thermal performance. Life-cycle cost analysis often shows advantages due to:
- Reduced energy bills from better insulation
- Space savings allowing more usable area
- Long service life with minimal maintenance
- Reduced HVAC equipment sizing
The exact economics depend on local energy costs, climate, and specific project requirements.
