Abstract

A suspended flooring system comprises a plurality of block members 11 of insulatingmaterial and a plurality of capping members 13 of insulating material, the capping members may be U-shaped. The capping members are fitted end-to-end along each beam 10 such that a central portion 14 thereof extends over the beam and opposite side portions 15 thereof extend down respective opposite sides of the beam. The block members are then fitted side-by-side between the beams so as to close the gap between opposite capping members and thereby form a continuous layer of insulating material which extends over the beams and which may provide a substantially flat surface onto which a screed material can be laid to form a floor surface. Also claimed is a floor structure. Also claimed is a method of constructing a suspended floor by: providing spaced apart beams; fitting insulating capping members on each beam; fitting several block members of insulating material to bridge the gap between beams.
