Abstract
An access floor panel (180) comprises a central core (2), a lower tray (20), and an upper flooring lid (10) which form an envelope for the core (2). The panels have a fire resistant seal or barrier (25) for sealing between the tray and lid (20, 10). The ends of the tray and lid (20, 10) are kept apart and the barrier (25) seals against the core (2) and each of the ends (181, 182) of the tray and lid (20, 10) to complete the enclosure. The seal (25) acts as a fire stop.
