Toyota Corolla - soundproofing

Noise reduction of the Toyota Corolla in the hybrid variant. Although the new model of this popular car boasts increased comfort, the sound insulation lacks sufficient efficiency. Practically only on the floor you will find a thicker layer of factory anti-vibration material, which tries to at least in some way save the well-known deficiency of this car manufacturer in the form of thin sheets. Since there is practically no insulation in the other areas of the car, this results in significant resonances and vibrations due to the lack of body rigidity. This is manifested by increased low-frequency noise, especially from the tires through the front and rear wheel arches, but also road noise penetrating through the floor and side doors. Weak noise insulation (it is completely absent on the doors and in the luggage compartment) is not able to prevent even noise of medium and higher frequencies, therefore it is necessary to additionally soundproof the car for greater comfort. The owner wanted to add as little weight to the car as possible, so we chose our discounted Standard Light package, which focuses on the front and rear doors, floor, trunk, front and rear side skirts and hood. We specifically focused on the rear wheel arches, which are problematic on this car. The Standard Light package offers, in addition to high efficiency, a very low weight of materials, thanks to which we can meet the customer's requirements for low weight. All areas of the car are soundproofed with 2 layers of materials, the first layer is the premium ultra-light anti-vibration material Comfortmat Premium Dark, and the second layer also consists of the extremely light sound- and heat-insulating material Comfortmat Vision. The result is a significant reduction in noise in the interior of the car and an increase in weight by only 40 Kg.
