Abstract: The invention provides an edge insulation piece (1) comprising a thin sheet of material (2) which is manipulated by bending, rolling or other forming to effect a long conductive path within a small cross-sectional area. In a preferred embodiment, a thin layer of insulation material (3) is interleaved between two layers of the thin sheet of material (2), which is folded around the insulation layer (3) during forming of the edge piece (1).

The edge piece (1) may be further coated over part or all of its length with a low emissivity material (13) to minimise radiative losses.
