ABSTRACT:
The invention relates to raised flooring panels which have excellent fire resistance. The panels of the invention comprise wooden panels whose undersides and side edges are covered with a metal sheet, and the panels being strengthened by downwardly projecting metal flanges. Such a panel can have better fire resisting properties than a metal panel which is liable to warp when there is a fire and which conducts heat to its upper surface so that floor coverings rapidly reach their flash point or than a wooden panel whose underside but not side edges are covered with a metal sheet.
