What do you guys use for sound deadening under the headliner?

What is everybody using ? I've seen some a headliner mat from dynamat but would rather get a real world opinion. Thanks

 

I used peel and seal works great

 

Dont use peel n seal, fat mat(rebranded peal n seal) frost king or any other home depot/lowes specials
Top 3 cld mattings at the moment according to massive test is
SDS
Murdermat
And knukonceptz kolossus

Or go for something more in your proce range
Just make it butyl based and not asphalt/tar
And avoid the crap i mentioned as they dont cover the main frequency range at dampening metal resonance like the rest

You could also add a layer of heat matting too for reduced interior temps

 

a real world opinion...
I have had peel n seal in my car for years...heat and sound proof...no problems...
last July trip to Ky. Wife complained of the A/C being too cold and it was on low...

 

I used dyna mat then a layer of dyna liner.

 

Peel n Seal in my Maverick also. It will damping the sound of rain, keeps the interior cooler in the summer and warmer in the winter. It does not smell like tar and never did. I will be using Peel n Seal on my next project(s) also.

 

Lmao real worl opinion
I guess real tests and waterfall charts showing what frequencies were dampened and how fast the fall off was isnt real world?

I have dyna matt xtreme in my car
Doesnt help with heat for crap..and evem tbough its one of the pricier cld matting it actually performed in the middle of the pack...while peel n seel was dead last

Cld isnt ment for heat...it actualy creates heat...its meant to absorb metal resonance...while doing so, what do you think that turns into? It surely isnt blonds and brunettes lol

Ive also sent the carinsulation crap to chris for testing as im testing it also due to the false or exaggerated claims the guy makes

Whole point of the mass testing was to find out what products really work and which dont, along with pricing to dictate their actual worth from their documented performance .

Theires a few cheaper cld mattings that work jist as good as the more expensize while theirs also cheap ones and expensive ones that perform terribly

 

Also some dont have good adhesive backings

Just because you hear a difference kn a product u used doesnt mean its actually working worth a damn
The so called car insulation crap. Claims to work just as well as dynomatt but it took a guy 2 layers of it at 100% coverage to only reduce 4db in interior noise...which is pathetic
..ontop of that its it rebranded Low E EZ Cool and resold of at a hefty price hike..

More reason for the mass testing to help consumers spend their $$$ more wisely over someones gimmick/pitch sale

Just like you dont need 100% coverage
Just wasting money and adding needless weight
..unless you do audio Competitions, then its all justified

 

you used one of the high end matts (dyna matt xtreme) and said it..."Doesnt help with heat for crap"? real world opinion
you've never used Peel and seal so how do you have any opinion?

 

Wasnt real world opinion
It was a real world result of dyna matt extreme doing absolutely nothing for heat to combat areas such as trans tunnel, toeboard, side of floor pan to where you cant leave leave your foot in one place to long or your feet get uncomfortablly hot.

My buddy used peel in seel.. ive been in the car before the installation and after
That and there was a scientific test that proves you otherwise...

Quit trying to justifiy your crappy purchase

Acording to your logic
I guess things like structural analysis programs to test structural integrity/fatigue span
Or any test to analyze performance is worthless as its not real world..

Hmm i guess manufacturers crashing their cars to get impact safty rateing dont matter either..not real world enough

What a joke
You must believe CLD is a all in one car insulation product...
I guess real world tests with real world results are worthless to you
I guess it i did a before and after of my car with both a DB gun and A heat gun its going to be worthless...
Thats essentialy what Chris did over at diyma forum when various members sent him product samples of what we all had left over...

Why would someone want to ignore test results and stick to the placebo effect of
Buying most expensive ..it must be the best..
Or buying a cheap alternative and ..it must do just as good...
Why?

The whole point of a mass testing is everyone doesnt have to physically buy and try every last product to see whuch works the best
And shows them if products are worth the price..

 

sounds like you based your opinion on what they said instead of...real world opinion
I've used it and it works...My....real world opinion

 

Hi Frank:
Me too ! I applied dynamat to my entire interior , doors, rear panel , floors front and rear of the Comet including the roof , also applied a sheet of insulation material which was " glued" to the dynamat ( real featherweight stuff) to the roof.. Then the Headliner. Works for me too ! Feels like the quiet of a " phone booth" when being driven . ( Do you remember phone booths? ha ) .. Anyway .. the insulating has improved the comfort level tremendously .

IF, and that is a BIG IF, I was into loud stereos competition wanting to reduce a certain frequency harmonics it might be different. But for the money Peel n Seal works. My floor doesn't get too hot to the touch and the product is staying where I put it and isn't sliding off any vertical surface I really don't care that I'm carrying around an extra 20 or 30 pounds because my car is a street car...not a racecar

 

Thats the most ignorant thing ive read in a while...
Well i guess FACT doest overrule Opionion...even though im pretty sure thats what everyone was taught in school..
It has nothing to do with audio competitions
It has to deal with a product working

You cant argue with fact....but you can argue opinion, because it isnt based on fact just preference ..thats why facts matter and opinions don't...

His whole post was about finding out what really works versus going by s sales pitch
Would you buy an engine claiming 400hp with no dyno sheet? Or would you want a supplied dyno chart?

Like i said theirs products out there for same money that blow the crappy peel n seal out the water as is proving more expensive products like dynamat, second skin audios Damplifier Pro that perform in the middle of the pack and not the top like their prices would dictate..

You can continue to use your home roofing product and your home duct work products and ill use something that works

I dont know why someone would willingly pay more for a product that doesn't perform any better then another...weather it be cheaper or more expensive

If original poster is interested in real factual results instead of opinions justifying their purchase ill PM ya
You can then find and use something that works baseing of your budget you want to spend

Ive used plenty of different CLD and the ines ive used , i wouldnt recommend mainly due to the lack of performance compared to cost ratio
Im not ignorant enough to avoid factual results over someone's Opionion on a product they dont understand the basic fundementals of
