The sound insulation of the cross member, end wall, front and middle floor is an independent assembly unit. All of the above parts are pre-stamped. The basis of all is felt, and some also have a coating of heavy, soundproofing film of different densities according to the type and modification of the car. The insulating elements for cars with steering on the left side are different from the insulating elements for cars with steering on the right side, as well as for cars with petrol and diesel engines.
Soundproofing crossbar (those. the upper part of the wall between the A-pillars of the body) (see fig. Soundproofing crossbar) made of stamped felt. At the top it is fixed with three plastic hollow large nails in the form of corks. In the lower part, it is glued to the body with two self-adhesive tapes. There are two types of cross member insulation. For vehicles with a petrol engine and steering on the left side, only felt is used for insulation. If the car has a steering on the right side or is equipped with a diesel engine, the felt insulation is covered with a soundproof heavy film.
Front panel insulation (those. wall located in the recess under the crossbar) (see fig. Front panel insulation) for left-hand drive vehicles are also of two types. In both versions, the felt forms a lining, but the soundproofing film covering it has a different density for vehicles with diesel and gasoline engines. In right-hand drive cars, the insulation is also made of felt, but the soundproofing film for cars with different engines does not differ from each other: it has the same density as in cars with left-hand drive and diesel engines. Similar insulation also on the front floor; middle floor insulation (see fig. Front and middle floor insulation) in cars with a gasoline engine made of felt; in vehicles with a diesel engine, the soundproofing film is also supplemented.
The floor and the end wall are covered with a three-dimensionally stamped rug, the pattern of which is unified for all vehicle modifications (see fig. Carpet assembly). The rug stretched from the top of the end wall to the rear edge of the rear seat. It is installed in the car after installing the air distribution to the rear floor, but before installing the sill panels, the center console of the dashboard and the seats. PVC pads are inserted into the mat at the place of support for the driver's left foot and also as thrust bearings at the pedals.
In the luggage compartment, the side walls are covered only with stamped mats, fixed at the upper edge with just two plastic clips (see fig. luggage compartment mat). The segment of the compartment behind the spare wheel is made in the form of an insert made of foamed polypropylene, in which there are cavities for laying car equipment (warning triangle, tools, spare bulbs, etc.) (see (pic. Insert in luggage compartment (for the spare wheel)). This box, as well as the spare wheel, is covered with a flat mat that forms the bottom of the trunk. The mat is mounted under the back of the rear seat on four threaded pins and secured with plastic threaded buttons.
