Soundproofing 2009 Fit for free. Project Roxul

So when I decided I was going to keep my 2009 Fit and not get a new 2016, I was going to do some stuff to it at it's now 55,000 mile mark. I installed the orange Koni's to my liking, and then I wanted to quiet the cabin noise down a bit. So Project Roxul was started.

I am not fully done with this project and I have had good results, so I am posting what I have done. I wish I would have driven on a couple roads and then did the fill job to get a proper imprint of change to compare. I did this over a 2 week period. 1st the back then a week or two later the front. I still want to pull the back hatch door plastic to add some there.

Doing this "I think" it reduced the so called "pillar" wind noise that now seems to actually be made by front wheel well wind noise that was reduce here. I also pulled up and filled the front door kick board area by the front seats as it was part of the hood opening piece that is in the photo.
I keep my rear seats down most of the time so I use to get a lot of noise from the back area, Not any more!! I fully lined the spare tire tub with 1 inch of separated/pulled apart Roxul, then screwed down the tire and added to open areas with more Roxul. I also used a very very light coating of hairspray to the final laid in pieces to reduce particulate floating. I know added fire issue but a used a torch and no real difference in flammability. Very light spray is the keyword here.

The picture with the hog pog of pieced together bits was the under the dash panel on the driver side and the same was done with the passenger side. I also added a 1/2 to 3/4 thick layer of Roxul the the front wheel wheel area that already had some factory soundproofing as seen in photos. For the rear wheel well covers I did not completely pull them out, I pulled the backside of them out as in opening a clam and added 1 inch thick Roxul separated sheets/chunks. Added a bunch to block noise coming from the inset storage area on the back passenger wheel well. Also rear light s were covered as in photo.

Here are some photos not in any specific order. I had 2 batts of Roxul insulation left from my basement so I went at it.

So do you want to put this stuff in your car....... yes, basically fire proof, mold resistant, and can get wet and dry with no issues.




Added note: If you are going to insulate any house of garage or anything this stuff is the best, bare none. Plus it is just a hair more then the pink stuff, that is crap.

What..... Come on. Do your homework. 8lbs Lbs. And you keep your gas tank below 1/4 because you worry about 6 lbs per gallon of gas?? Who cares. My car is quiet now.


One full package

37.8 lbs includes plastic wrap.

12 batts per package

I used 2 batts so far.

= so far: 6.3 lbs


I expect to add 1/2 batt more.


So Project Roxol total weight would at the est. high side would be: 8lbs.


8lbs total weight!


CORRECTION :::: I used 1 and 1/2 batts. SO total weight is 6 lbs


Corrected weight is 6 lbs.

I updated the link to the cheapest product you can buy, and yes it is misleading after looking at it from your view. But you figured it out that it would cost you $42.00 to do. Well worth quieting down a loud car.

I kinda think this is genius!! Who needs to spend hundreds of dollars and add 50 lbs to your car when you can spend a few bucks and add a few pounds...

I just wish I could make head or tail from the photos...I suppose I'll be able to when I head out to my car and look around.

So, how does the difference feel and or sound to you? And what did you do that may have reduced pillar wind noise? I'm very interested to get some relief there...

Perhaps now some reflectix on the door panels to calm them down a touch?

pics 1&2 self explanatory, pic 3 passenger rear tail light. 4&5 self explanatory, pic 6 driver side side kick plate off and is in pic 6&7. Also in pic 6 look at top of pic see the gray factory soundproofing, now look at pic 9 that is where I added Roxul to the place you looked at the top of pic 6.

Next will be the side doors. I think I will have to buy another 12 batts or 1 package to do the doors. Well worth it.

And to your question about pillar noise, some of what you think is pillar noise is wheel well/tire noise.

were you able to tame wheel well noise at all?

Do you notice a good difference having done this?

You bet, I have my back seats down most of the time and I would get a ton of road noise, now it reduced by 50% to 60% plus. And I have not done anything to my doors yet. Remember I added Roxul to the under dash panels that keeps noise coming down from the upper firewall and engine. I also added a big chunk behind the center console . I may even go to that extreme too...pulling and soundproofing the center console between the seats. So total est weight added could be in the 20 lbs area, WORST case scenario or 3 gallons of gas added added weight.

Update: I did the doors a month or two later and that helped a bunch. 6 months later I sold my Fit because we could not sell my wife's 2013 Hyundai Elantra GT when we bought a lease return Rav4 for her. I was $200 away from trading it in , but the dealer would not move up $200. Bad move on my part, I never would of thought Hyundai or at least model had such bad resale value. I payed $300 extra on insurance holding the car and it never sold $1,000 under Blue Book. I did not want to take any more of a hit so I kept the Elantra GT and sold my Fit.... that sold in 1 & 1/2 day for what I was asking for. Go figure.

How did you do the doors? When the windows move up and down, wouldn't that cause the insulation particles to get loose?

I did them inside the door panels with some double sided tape. Look at my pictures on how I pulled it apart to change the thickness I wanted. Also I pulled 1/2 way out the rear wheel well panels and put a layer all the way around the wheel tube, I did not just stuff the the insulation in the hole as it appears in the photo.

Interesting idea! Though I'd be worried about mice getting into the insulation and making nests all over it, as they seem to do in more rural areas.

Once they are INSIDE your car with or without this soundproofing it is game over. Most panels have its y-bitsy thin sound proofing. This will not be passed by a mouse. Again, any mouse inside your car it's game over.
