DOC AIRBUS | AMM A320FINSULATION (THERMAL AND ACOUSTICAL) - DESCRIPTION AND OPERATION
** ON A/C NOT FOR ALL
1. General
The thermal insulation does the following:
** ON A/C NOT FOR ALL The thermal insulation does the following:
- minimizes the loss of heat from the fuselage,
- stops the formation of condensation,
- reduces the noise level in the fuselage.
2. Component Location
The thermal insulation is a material and not a component. This material is distributed through the pressurized fuselage, and is of different thickness, and installed in different ways.

3. System Description
The thermal and acoustical insulation is made of insulation blankets and insulation foam bonded to panels.
The insulation blankets have ventilation holes on one side. Above the cabin floor level, the holes are on the inboard side of the insulation blankets. Below the cabin floor level, the holes are on the outboard side of the insulation blankets.
In the cargo compartment, insulation foam is bonded to the bottom surfaces of the floor panels.
The thermal and acoustical insulation is installed in the following areas:

A. Types of Thermal and Acoustical Insulation
(1) Between the Frames
The sidewall blankets are installed between the frames. Pins and washers and/or polyamide brackets attach the sidewall blankets to the stringers. The sidewall blankets have cutouts for the structure brackets. The sidewall blankets are attached to the frames together with the frame blankets.

(2) Over the Frames
The frame blankets are installed over the frames and over the edges of the sidewall blankets. Pins and washers and/or cable brackets attach the sidewall blankets and the frame blankets to the frames.
The frame blankets are installed over the frames and over the edges of the sidewall blankets. Pins and washers and/or cable brackets attach the sidewall blankets and the frame blankets to the frames.
(3) Over the Structure Brackets
Because of different cabin configurations, some structure brackets are not used. Small cover blankets are installed over these brackets and over the openings in the sidewall blankets.
