Abstract

Fibrous material, such as mineral fibre, glass fibre, basalt fibre etc. is treated by a method involving treating a plurality of discrete fibrous chunks, each chunk comprising a mass of entangled fibres, by a mechanical tumbling action such that each chunk forms a respective denser, rounded fibrous cell with entrapped air. The cells have properties that make them useful in a wide range of applications. In particular, the entrapped air of the cells means that the cells have insulation properties, thermal and acoustic, useful in many contexts.
