Abstract

An insulation pack for thermally and acoustically insulating an aircraft has a mat formed from an insulation material, and a casing film which completely encases the mat. The casing film has drying openings, each closable a cover that is connected to the casing film. Each cover has a coating substance, the planar extent of which varying as a function of the relative air humidity of the air in the interior of the insulation pack such that each cover moves relative to the casing film, as a function of air humidity. The associated covers are adapted for assuming an orientation which, below a predetermined relative air humidity, closes the associated drying opening and which, at higher relative air humidity values, at least partially opens the associated drying opening.
