Abstract
The sheet material is first indented to provide a relief pattern not exceeding 1 cm in height and consisting of a large number of raised portions with a generally flat area surrounding them. After this, the entire sheet is further dimpled and projections or dimples of greater height and large base area so as to include a number of the first relief-pattern projections. A preferred arrangement comprises 5 mm square relief-like projections separated by 3 mm gaps and projecting up to 1 mm from the surface; the larger dimples or projections are approx. 50 mm in diameter, 15 mm high and at one 100 mm centre-to-centre. Used in particular for foil thermal insulation in nuclear power plants. Improved insulation and reduced cracking leading to boundary layers which disturbed the insulating action is obtd.
