Mineral fibre-based sandwich structure and method for the production thereof

摘要

A sandwich structure (2) comprises a core (20) and two facing elements (21, 22). The core is formed from a product (1) based on of mineral fibres obtained by internal centrifugation associated with drawing by a gaseous current at high temperature. The mineral fibres are crimped. Independent claims are also included for: (a) the fabrication of this sandwich material; (b) the construction of an architectural insulating element using this sandwich material.
