Expanded polystyrene foam board is used as the basis for many different projects used in commercial construction. Melt away ceiling tiles, made from 1lb density expanded polystyrene, are used instead of traditional fibreboard when sprinkler heads are installed above the finished ceiling. The tiles are designed to ‘melt away’ so the heat of the fire can set off the sprinkler system. Often used in an office that has been set up in a warehouse situation with an existing sprinkler system.
