Abstract

The lintel, made from a metal or an alloy such as steel, comprising an inner flange 23, an outer flange 27 and, what would be in use, a cavity bridging component. The cavity bridging component comprising a number of discontinuities 5 creating a thermal barrier by forming a tortuous path for heat transfer between the two flanges. The lintel may include an elongate slot 31 substantially extending the length of the lintel such as to create a lintel made up of two parts, which are bridged by reinforcing elements 33 at intervals along the lintel s length. The discontinuities may be rows of elongate slots staggered such that the gap between slots on one row coincides with a slot on an adjacent row and vice versa. The discontinuities may also be circular, zig-zag or any shape capable of providing a discontinuity in order to retard heat transfer from one flange to the other. A base plate may be welded to connect the two flanges of the lintel. An insulation member may be placed on at least one exposed flange of the lintel.
