composite / Panelised / Insulated Panel
Structural Insulated Panel (SIP), steel-faced (50mm, 75mm, 100mm, 150mm, 200mm)
Steel-faced PIR panels with declared ? = 0.022 W/m?K and U?values about 0.44?0.10 W/m??K depending on thickness (Kingspan panel data).

At-a-glance signals
Steel-faced PIR panels with declared ? = 0.022 W/m?K and U?values about 0.44?0.10 W/m??K depending on thickness (Kingspan panel data).
Overview
Executive summary
Steel-faced insulated panels typically use PIR cores. Kingspan panel data list declared thermal conductivity of 0.022 W/m?K and U?values from 0.44 down to 0.10 W/m??K depending on thickness. These values are representative for steel-faced PIR sandwich panels in roof and wall systems.
