XPS (1995) - 10 cm - flat roof
XPS board, 10 cm thick, with ballast (tile supports).
Proposed performance for reuse
Thermal conductivity: 0.033 W/mK
Compressive strength: ≥ 187 kPa
Dimensional stability: Meets the current requirements.
Water absorption: Possibly higher water absorption than the current limit value of 0.7 vol%.
