Abstract
Balls changing volume when activated efficiently filing a gap providing acoustic and thermal insulation. A method of manufacturing of means for acoustic and thermal insulation, particularly at high temperatures, comprising providing an insulating and damping material; shaping of the insulating and damping material having geometric shapes, such as spherical or elliptical shapes, by a shaping processes, such as forming into a ball and/or foaming up.
Claims18
A method of manufacturing means for acoustic and thermal insulation, particularly at high temperatures, comprising:
- providing an insulating and damping material;
- shaping of the insulating and damping material having geometric shapes, such as spherical or elliptical shapes, by shaping processes, for example forming into a ball and/or foaming up.
Means for acoustic and thermal insulation, especially at high temperatures comprising an insulating and damping material, said insulating and damping material being a ball having geometric shapes, such as spherical or elliptical shapes, by a shaping processes, such as forming into a ball and/or foaming up.
A sound absorber having acoustic and thermal insulation properties comprising:
- a first surface;
- a second surface;
- a gap formed between said first and second surfaces;
- a plurality of balls placed within said gap, said plurality of balls comprising balls having at least two different diameters;
- and
- wherein said plurality of balls increase in volume only when initially activated and do not thereafter change in volume,
- whereby said plurality of balls and the at least two different diameters efficiently fill said gap.
