How to insulate or soundproof roof??

[69CHARGERMD]

I am not using a vinyl top on my 70 challenger,,,,and put a new roof on the car,,,,,
Question,,,,
What can I use for sound proofing the roof before I install the headliner ??
I have some phat mat that used on the floors, etc,,,,but wasn't sure if this would be a good option for the roof or if it would not stick to the roof over time,,,,,
Any thoughts on lizard skin??

Trying to keep heat out,,,avoid the car sounding like a tin can inside,,,etc

Thx for any thoughts.

Hey, yeah I covered my roof with dynamat then installed the headliner, roof sounds like lead now when you tap on it.

Cool. I will put some of the phat mat I have and that should work. Thx guys !!

I too used NOICO sound deadening mat and also the die cut insulation that I clued with 3M adhesive to the NOICO sound deadening. Might be a little overboard, but what the heck.  Good luck.

Dynamat is one of the soundproofing mat you could use.

Thanks guys.
I used phat mat and used some 3M to keep it in place. Hopefully it doesn't sag with time.
Thx guys !!

Fat Mat Mega Mat has adhesive like dynamat.

djw,
Thanks for the reply....
The Phat Mat I have seems to have some adhesive,,,but didn't seem very sticky ( 65* here today ) ,,,especially for the roof
( for the floors and doors I just peeled off the backing and layed it in place )
The 3M adhesive seems like liquid cement once it dries,,,so I added it as well for the roof portion.

Plan now is to get the headliner in,,,,and start more work on the interior.....

Curious how you guys did your doors ??
did you just do the frame portion that is covered by the door panel ? or did you guys stick it to the actual inside portion or skin of the door ( on the other side of the glass ) ?

Hey Doug , myself I covered the door frame behind the panel. Doors sound really solid when closing and I think it is better than putting it on the outside panel as that would leave a big gap where road noise could still enter the cabin but that's just my  .

Car is looking awesome BTW

I installed my NOICO SOUND DEADENER to the inside door skin, refer to pic below. Sorry I don't have a close up handy but I think you get the jest of it  . I also did the same with the rear quarter panel behind the quarter glass. I will finish up with a layer of sound deadener on the inside door/quarter glass in lieu of plastic dust cover........sweet! Good luck!

Darcy, did you put sound deadener under the dash where the factory jute for the heater box is?

[cordodge]

I did, right from the bottom of the windshield to the bottom of the rear glass and all of the roof along with the sides,100% covered

One thing I've seen done on roofs that I feel makes sense, cut the sound deadener into small squares, maybe 3x3 that way if a square comes loose it doesn't pull a whole roof section loose just a small square....   And yes the 3M spay adhesive has got to help.... Thought I would look for the high temp version....
