The fireproof acoustic and thermal insulation material is a sandwich structure with two aluminium outer layers flanking polyethylene films forming air bubbles. At least two films (2) form the air bubbles (3). They are bonded by heat, evenly over at least one surface to contain at least one inner layer (4) of polyethylene foam. The outer surfaces are covered with a fireproof layer (1). The air bubbles are covered with nylon to increase their mechanical characteristics.
