Sound Deadening

[Kyle@Apollo-Optics]

You're gonna need a decoupler between your CLD titles and your MLV....Closed cell foam works great. The MLV needs to be decoupled in order to "block sound"
Also, if there are any resonances left over, IF the MLV is in direct contact with the resonances, the resonances will pass through the MLV if there is not a decoupler in place..
Sheets of CCF are cheap

I agree. That’s why I buy my MLV with closed cell foam attacked already. That way you do it once. With CLD your wasting your time and $$$ doing more than 25% of the sheet metal.

Here you go. This is the exact same stuff.

Cut it into squares using a sharp exacting knife.

Aside from dynamat and the squares placed inside the doors. Would there be anything else needed?

I am aiming on making the truck as quiet as possible.

Definitely don’t lay dynamat over where the Vapor barrier goes. EVER! If the door, locking mechanism, window, etc ever has to be serviced, the person doing the service will have to cut all of that material out and you will be sol.

Do it the right way and build replacement abs or aluminum vapor barriers. If using ABS, which I recommend, it takes all of 15 minutes to make them.

See pics.

What material did you use to pad the door? It looks thick.

Damplifier pro inside the door. Luxury liner pro as a decoupler on the outside of the door. Then more damplifier pro on the actually door panel to eliminate noise and rattles.

Did you get the one by second skin?

Yes, all second skin.

Yes, all second skin.

I just got about 76square feet of dynamat extreme. Thinking I might just need the closed cell insulation to put on top of the door.
