Sound deadening

[Theo Ray]

I’m soon to do my first build, and willing to fork out the extra money for sound deadening since I have been told it’s worth it. Is there any brands/materials you recommend?

Resonix if you want premium

Siless max 120mil for more cost effective
Siless 3 in 1 good aswell

I personally use siless 120mil pretty much everywhere
Then in some areas I add a layer of the siless 3 in 1 over it

For roof I recently laminated my jeep patriot with half inch mdf using 8x PL
First time using mdf panels for roof
The roof is solid! Always using this method for roof now

What Resonix products would you say is best for door cards? Is the decoupling foam the best

 

[supernov4]

Depends what you are trying to achieve

A decouple foam is just that, a decoupler
It is used to decouple mass loaded vinyl or "MLV" from surfaces that can rattle
It acts like a shock absorber does not deaden sound

To add mass and reduce resonance in a panel you can use a decent cld tile
Then if you want to reduce road noise you can add a layer of resonix "barrier" as full a sheet as possible little to no seams
It is like MLV also has foam on both sides as a decoupler

Deadening properly is a big job so heads up

Another good trick is to get a roll of fabric tape like hockey tape or harness tape

When you have panels off if you see any cables that look like they might touch metal you can wrap some of that around to quiet any vibration against surfaces
It's also good for seams and such when 2 plastic panels go together or when plastic goes on metal it can act as a gasket softening any vibrations against mating surfaces

Also some foam weather stripping from the home depot could come in handy along the edge of door card to help seal and eliminating vibration

I'm not a big fan of noico either
Heard some decent reviews so I figure I'd grab some didn't work out too well, the foil is just too thin and I don't recall it coming in anything thicker than 80mil

Although I do use the "inferior" stuff on non critical parts like more structural stuff metal frame, ribs, beams so I don't waste better stuff, even though probably not needed

Okay thank you very much for the help

Okay thank you very much for the help, Do you think it would worth buying resonix’s stage 3 door cards deadening kit for the doors and then buying the rest separately?

If you contact resonix and talk to nick
He can guide you through it much better than I can as those are his products
Just tell him your vehicle and what you are trying to achieve

Recent observation....
Ie just used amazon basic CLD, I know about the drama Nick is trying to cause vs thickness,
Ive had old stuff & new, its minimal, also depends what size sheets you get...

AB 80mil
NVX 91mil
Most recent project I used NVX silver cld 120 mil. Lots of people from my DD speak highly of it....

Compared the foil layer of the nvx to the AB
foil layer is way more rigid & thicker on the AB .007
vs nvx .004

The nvx foil manipulates like paper vs the thickness & honeycomb characteristic of the AB makes it more rigid

I went ahead & used the NXV, but feel that my initial concerns were verified from the results after laying it on.
Really had to cover panels thoroughly to get the thud results I was looking for & from what I was use to using the AB on 2 other vehicles in the past...

I dont think its just in my head...
The foil layer on the NVX was nothing special, thin & very pliable....
Just didnt give me that warm fuzzy feeling...

Just my observation...

Does the nvx 91mil and 120mil use the same foil?

Honestly, buy what you can afford. I used NOICO on a car and it was just fine. I used the 80mil and I used the thicker NOICO Red 150ml with the 80mil as well as 150mil on the inside of panels.

Noico Red 150 mil 36 sqft Liner Car Heat and Sound Insulation

Noico Red 150 mil (4 mm) closed-cell polyethylene foam is the best alternative to rubber foam. Liner Car Heat and Sound Insulation

No idea, they / nvx isnt very descriptive breaking down the thickness of the various layers...
