Hey guys, im about to install 120sqft of raammat sound deadening mat plus 70sqft of ensolite ps (open cell foam) in my camaro this weekend and was wondering wuts the best placement for the mat and for the open cell foam i have?

Are there any specific spots i should layer up on the matting or any specific spots i should be using the foam?

And altho, ive already researched it a bit, do you guys have any install tips? every lil bit helps, thanks in advance

Raammat, you want to put on any large panels that can reverberate like a gong... door panels, floor pans, etc. I think more than one layer is excessive. Some experts will tell you that just one little piece in the center of a large panel (anchored on its edges) is adequate. I think a lot of people go overkill with this. All you want it to do is damp panels from vibrating.

Ensolite, you want a patch behind speakers (like a baffle in a large home speaker enclosure), and over areas where you expect external noise... like the firewall for motor noise, over the rear fenders for wheel noise, wherever wind noise is high. I've debated putting some on the top side of my T-top shades, because the glass roof on our cars is the source of a lot of wind noise.

Thank you for the help man! I have enough raammat thar ill likely cover everything as much as possible including doors and roof. So ensolite behind speakers, anywhere else I should I focus it?

^ The trunk area. When I did my deadening install, I covered every square inch of exposed metal throughout the car. Trunk area will kill some exhaust drone, not to mention it's a big rattle spot with subs installed.

I just bough 90sq ft of secondskin damp pro. Its comin this week. Are you doing the roof also? I'm going to order some cell foam also. Just not sure how much yet. With 120sq ft I'm sure you can cover everything.

I bought enough so that if I'd like to, I can addan extra layer in the trunk area and trans tunnel. And yes, I plan on doin the roof as well

There is a lot of literature out there on this subject.

Best resource I have found.

The asphault based or similar materials like dynamat or Raamat are designed to stop vibration and not absorb sound. It does stop vibration but does a pretty poor job of stopping sound from coming into the vehicle. Do not just coat every square inch of your interior with the Raamat and expect the road/wind/exhaust noise to be significantly reduced because it won't be. Trust me, that is what I did and it didn't work. The best way to stop road noise is by using the Raamat on large panels like mentioned above, anything over 75% coverage is useless, then use a closed cell foam, layered with MLV. Most guys make removeable panels for the different sections of the car and attach them with velcro strips. Everything is explained perfectly in the link above.

Agreed. Although I don't think anything said on this forum will ever stop people from putting in multiple layers of CLD, and becoming enchanted with photos of shiny foil canvassing an entire stripped interior.

Fudge. Now I want to redo my ghetto sound deadening project! Thinking of using those tiles along with the MLV on top but how many square footage do you guys recommend?

I was thinking:

- 25 of the 6"X10" CLD tiles
- 67.5 sq/ft of the MLV
- (1) 1/8" thick - 36"X54" CCF (for center console)

Sound good? Sorry for the thread hijack!

Have you looked into returning your Raamat for some of the products mentioned in this thread? I'd hate for my car to smell like asphalt and have issues with adhesion on vertical panels. Plus it sounds like 120 sq/ft of the sound deadener is overkill.

It's dynamat, fat mat, peel and seal that have asphalt and sticking probs so im clear :)

Oh, OK. What about returning some of the Raamat? Are you still going to cover the entire inside with the Raamat?

I used StreetWires Noise Killer 3.0MM - Really did a great job imo.

I though the owner of ratmat owned a roofing company and it was just renamed and sold as car material. Google it. I could be wrong though. I just got my secondskin damplifier pro in the mail. I got 90sq ft and this shit is heavy! Makes me really hesitient to use it all.

here is how mine came out after i was done with the raamat and the extra layer of padding. i also redid my carpet padding with Jute, but didnt take pictures of that. no more Torque arm wine from the relocated mount. nice and quiet inside on the freeway with the windows up. i payed special attention to the area on the tunnel near the transmission and torque arm mount. these were the areas i deemed to be the most noisy.

You're confusing raammat wit fat mat I think. Its fat mat that is owned by a roofing guy. Raammat is certainly diff going by just looking at the adhesive and the foil layer compared to the fat mat (I got my hands on some to compare) the adhesion is also much stronger on the raammat. Worth noting, is that before I installed the ensolite (ccf), the sound level didn't change much from just the raammat. Once I put in the ensolite it was like nite and day. I'm EXTREMELY pleased wit the results and I havent even done the roof. I'd say I covered about 75% wit the mat and about 90% wit the ccf

Yes I never heard of raamat. Though you misspelled it. Ratmat is the roofing stuff. What ccf did you use?

i used the same companies ccf which is called ensolite. i got the ensolite ps which stands for peel and stick, as they have another version that requires a spray or other form of adhesive

and btw, i was on my phone before but noticed your install pics and it looks pretty solid!!

are you gonna put any ccf on the sail panels or the wheel well parts tho? seems to me like that would be a large source for road noise

yup, that is the stuff i used too, the black stuff on top of the shiny stuff. got the Raammat and the Ensolite ps from the same guy, good discount to cause he was in the military. so talk military with him and he gives you a good discount. just be prepared for a ridiculously long conversation.

Jus' thought of something: How 'bout taking off your front wheel inner fender black plastic thing and covering the inner top layer with some MVL? That could help with tire noise no?
