【QATTARA Sound Absorbing & Sound Insulating Sheet｜A 4-Layer Structure That Enhances Cabin Quietness and Sound Cohesion】

This is a sound-absorbing and sound-insulating material suited for those who are bothered by road noise in the cabin and noise around the floor, or for anyone who wants to listen to car audio a bit more calmly.

QATTARA is a four-layer structure consisting of a non-woven fabric layer, a 2 mm-thick heavy-layer mastic, a 4 mm-thick foam rubber sound-absorbing layer, and an adhesive surface. It is used for installation aimed at reducing the sounds and vibrations that travel into the cabin—not simply by adding thickness, but by combining materials with different roles.

In particular, this is a sheet suitable for installation on the floor, bulkhead, and trunk floor. If you’re concerned about sounds coming in from the cabin floor and around the cargo area, or if you want to achieve an even quieter environment after deadening, you’ll combine it while considering the installation coverage.

As an example, first use a vibration-damping sheet such as StP AERO or BombAero to suppress panel vibrations, then install QATTARA on top. Furthermore, by combining a sound-insulating sheet Accent6 as the second layer, you can create an installation that balances vibration damping, sound insulation, and sound absorption.

However, sound-insulating materials are not something you just apply over a wide area. Because the shape of the metal panels, the fit of the interior trim, and the thickness you can apply vary by vehicle model, it’s best to decide the installation coverage and combinations while checking the actual vehicle. If I were doing it, I would confirm how the sound enters and how it’s used, and then perform an installation using the right materials in the necessary locations.

If you want to enjoy music in a quieter cabin, if you’d like to reduce road noise as much as possible during long-distance driving, or if you’re considering sound-insulation installation around the floor or trunk, let’s organize the details together according to your vehicle model and intended use.
