All cases
PIR (2011) - 8 cm - flat roof
PIR board, 8 cm thick, mechanically fixed and with MCGF facing.
Proposed performance for reuse
Thermal conductivity: 0.0260 W/mK
Compressive strength: ≥ 150 kPa
Dimensional stability: Low risk of extreme expansion at high temperature (70°C) and high relative humidity (90%). No risk at low temperature (-20°C).
Water absorption: Possibly higher water absorption than the current limit value of 2 vol%.
