Dammit, engine compartment insulation is eaten up.

Meal. I just replenished washing water and saw that some little animal had my insulation mat snapped in the engine room. Does anyone know how expensive it is to replace it (or has someone already had it done and knows about a price)? Do aggregates/wires have to be removed, because the mat has holes? Do not want to pay a lot of wages at all, so that such a thumpy foam mat is exchanged. For hints I am grateful. Sorry for the sc Hilten images, is just a mobile phone camera. EDIT: Only one image, because uploading and linking here is somewhat uncomfortable.
