Summary
Sophon attributed the failure to condensation from air-conditioning pipes above a recessed ceiling section in parliament’s B2 canteen. He described the panels in that area as Smart Board.
According to Sophon, the air conditioning had been kept running during a series of parliamentary meetings the previous week. When the system was switched off, condensation dripped from the pipes onto the ceiling, causing the panels to swell.
