Abstract
This invention relates to insulation materials and, in particular, to thermal insulation materials having heat reflective properties. In particular insulation material according to the invention comprises a random array of elements as herein defined having at least a portion thereof deformed so as to increase the resilience of the elements and to assist in forming spaces between adjacent elements in the random array. In this specification the term element is used to include filaments of different cross-sectional shape, for example, circular, square or rectangular, strips of uniform or non-uniform width and/or thickness, flakes and platelets of regular or irregular geometric shape and of uniform or non-uniform thickness, and the like.
