Abstract

A protection product has thermal and acoustic barrier characteristics such that it satisfies the requirements of the standard 14 CFR, part 25 issued by the Federal Aviation Administration. The product is designed to be applied along metallic and composite structures, such as aircraft cockpits, boat hulls or the outside structures of trains or of other means of transport. The product is essentially in the form of a “mat” consisting of one or several fiber layers, preferably glass fibers, enclosed in a sheath. The sheath generally comprises at least one first support, preferably made of an organic material having sealing and anti-condensation properties, and an impregnated mica paper. The mica paper preferably has a weight per unit area of less than 50 g/m2 and comprises flakes of mica with a form factor greater than 1000.
