Abstract
This invention relates to the heat treatment of thermally insulating fibrous materials, in particular envisaging the use of thermosetting resins as binders. The material is subjected to a field of ultra high frequency radiation, with the water content of said material and the intensity of the radiation field adjusted to suitable levels, and to a current of hot gas. This method of treatment provides a highly advantageous energy yield and very good homogeneity of the characteristics of the product. It is particularly suitable for insulating shells based on mineral fibre felt.
