Abstract
A substrate includes a fibrous material in the form of mineral wool of insulation type and/or glass fibers of reinforcement type, and a coating provided over at least a portion of a surface of the fibrous material, the coating having photocatalytic properties and including at least partially crystallized semiconductor material which has photocatalytic properties and which is of the oxide or sulphide type, and a bonding agent configured to adhere fibers of the fibrous material to each other, the bonding agent including an adhesion promoting agent configured to promote the adhesion of the coating to the fibrous material. The bonding agent is selected from one of an adhesive agent for mineral wool, a sizing agent for reinforcing threads, a bonding agent for a mat or web obtained from reinforcement threads, and an adhesive agent for a web obtained from glass wool.
