Sound deadening Fat Mat with jute
I am doing a full frame off resto on my 69 and now I am looking at what to do for the floor in the cab. I want to install Fat Mat over the floor, back wall where the gas tank was and the fire wall. Here is my question, do I still install the firewall 3 mats on top of the fat mat? I tried a search and after reading thru a bunch of pages, I could not find the answer to this question.
Thanks for comments. |

Re: Sound deadening Fat Mat with jute
I would, if nothing else to cover up all (or as much as possible) of the shiny aluminum.
FWIW: When I restored my '52, I installed GTMAT onyx butyl (same spec as Dynamat but significantly less expensive) on the toe panel, fire wall, cowl, roof, door skins, and back cab wall (behind tank). I did not install on the floor as that year truck only uses a rubber floor mat and I did not want the aluminum sound deadening to show or get "ugly". So, I used 3M Body Schutz on the underside of the cab floor. Body Schutz is an undercoating and affective sound deadener all in one. It worked great! I did install the factory firewall pad as well. Where the GTMAT wanted to show through at the edges of the firewall pad, I covered it with anti friction tape so only black showed through (i.e. visually insignificant). Check out GTMAT!

Re: Sound deadening Fat Mat with jute
88stranger I would do the same as Davidf suggested I have been doing upholstery work for 25yrs. I have been using the fatmat products for 5yrs now and love the stuff and very reasonable, you can do your truck easily with one roll 50sq for $100. I do the floor and the back of the cab inside and inside the doors what a different,s it makes.They make it with or without their logo, you can ruff it up with some scotch brite and paint it as well. Hope this helps.

Re: Sound deadening Fat Mat with jute
I used it all. I put Dynamite down, then closed cell aluminized insulation, followed by MLV (Mass Load Vinyl) the the jute, then the carpet. You can see this on my build thread.

Re: Sound deadening Fat Mat with jute
Well, as quite as I think I can get it. At least now conversations are easier to have at highway speeds and the radio sounds better.

Do you think it made that big of a difference in the sound? I may take mine back a part and add it but just didn't figure it could make that much difference in the over all sound quality of the cab.

Re: Sound deadening Fat Mat with jute
I did the same. 80 mil fat mat and carpet which had MLV and jute preinstalled. Hard to say how much one did over the other since I started with bare metal floor. It definitely keeps out plenty of heat. Before I couldn't put my hand on the floor because of all the extra heat. Now it's not a problem.

100 ft should be plenty! My truck is pretty dog gone quite for it to be as old as it is. I also put the road kill inside the door per my local stereo shop guy. I did a 12"x12" in the middle of the door and then 6"x6" in each corner as close as I could get it. When I shut the doors now they are solid!

Re: Sound deadening Fat Mat with jute
Wow! Those pictures are great and you did a nice job on that carpet. So much better then the typical lose fitting kits look.
I noticed you also wrapped ur gas tank. How's that working for you? Does it help quite things down or why exactly did u wrap the tank? I just bought Fat Rattle which is just the .80Mil not the .50Mil which is Fat Mat I'm pretty sure. That said, I've been spending the extra on Dynamat for the last 3 projects and after reading all the feedback and reviews wish I didn't wait so long..... Shawn |
