A quieter van starts on bare metal
Damplifier Pro is a butyl sound deadening mat from Second Skin Audio. It sticks to the sheet metal of your van and stops the big panels from ringing, so road noise and rattles drop before you add anything else. It goes on first, before insulation and before your wall and ceiling panels.

How much do you need?
You don't need to cover every inch. About 60% coverage, focused on the large flat panels (walls, roof, floor), does most of the work. More helps, but less and less as you get close to full coverage.

FAQS:
When in the build does this go in?
Early. It goes on bare metal, before insulation and before your panels.
Do I need to cover the whole van?
No. Around 60% of the large panels is the sweet spot.
Is this insulation?
No. It quiets vibration in the metal. It doesn't keep heat in or out, so you still need insulation.
