Installation notes

Expose the mounting surface and remove debris, rust and waxy oils.Clean the surface with denatured alcohol; do not use a degreaser that leaves a film.Cut the sheet to size with a utility knife.Remove the release liner gradually and press the butyl layer firmly onto the surface.Use a hand roller to remove air pockets and create a permanent bond.Wear gloves because the foil edges can be sharp.

COMMON QUESTIONS

Sound-deadening material helps control vibration and resonance in metal or fiberglass panels. This can reduce rattles and road noise while helping your speakers produce cleaner, more defined sound.

Start with panels that vibrate around your speakers and speaker pods. Doors, rear panels, floors, roofs, wheel wells and trunks are also common treatment areas. Always follow the installation areas and surface recommendations listed for the specific product.

Not always. Strategic placement on large, flat and vibration-prone areas can provide a noticeable improvement. Check the recommended coverage information on this page when planning how much material you need.

Remove dirt, loose material, rust and oily residue before installation. The surface should be clean and completely dry so the adhesive can make firm contact. Use only a cleaner that does not leave a residue or film.

Most installations require a utility knife or heavy-duty scissors, gloves, cleaning supplies and a hand roller. Gloves help protect your hands from sharp foil edges, while the roller removes air pockets and firmly bonds the material to the panel.
