For thermal and noise insulation, the floor surface in the body and the floor casing above the gearbox are covered with 2 mm thick bitumen noise-insulating sheet gaskets. The gaskets on the floor casing above the gearbox are reinforced with paper to prevent bitumen leakage in vertical sections during drying. During body drying, the gaskets are fused with the primed floor surface.
Between the roof panel and the roof reinforcements, on the upper flange of the windshield frame, in the stiffening ribs of the inner hood panel, anti-vibration pads made of expanding rubber are placed. The ends of the roof trim arcs are installed in plastic anti-squeak bushings.
Thermal and noise insulation of the roof is made of super-thin fiberglass impregnated with resins, which are glued to the roof panel in the cabin.
The front part of the floor, the front shield, the lower part of the air intake box, the side panels of the front are covered with textile-bitumen heat and sound insulation pads. The rear part of the floor, the arches of the rear wheels, the rear shelf, the partition panel adjacent to the luggage compartment are covered with felt pads.
Reinforced bitumen pads are applied to the inner surface of the outer door panel, with magnetic powder added to the bitumen to prevent the pads from peeling off the surface as the body passes through the painting and drying chambers.

To prevent parts from creaking while the car is moving, bitumen gaskets are installed on the door reinforcements, rear fenders and upper corners of the windshield frame.
The anti-noise mastic covers the underbody, rear wheel arches, inner surfaces of the front fender cavities and mudguards located behind the front shield.
To avoid noise and knocking, rubber buffers are installed under the rear corners of the hood, on the fuel filler cap, on the lower pins of the radiator grille, and on the brackets of the door window stops.
Anti-noise plastic tubes and struts are installed on the ends of the trunk lid torsion bars, and on 2102 and 21021 cars on the ends of the tailgate torsion bars.
