Cab Noise Deadner

[lugnut123]

 What is a good inexpensive noise deadner I can install under the floor rubber mat. I remember this was brought up before but cannt find it on the search. 15 pound roofing felt.?? I have some aluminum foil insulation to go in the doors and roof. noel in nm

On my truck most of the noise came through echo,  the holes in the fire wall and poor or no seals on the doors. I plugged all holes from the engine side, and new seals from Steele. What a difference. I have some rubber padding on my floors and a rug from Lowes. I bought some bubble foil insulation from Lowes, painted it flat black and used it for my interior. Some day I may go the 'cardboard' interior route, but not soon.

 

For the trek to the now famous BBQ I needed some deadener for inside the doors. I spied an old pillow tucked it into the cavity and wow the door went thud, so I packed the doors with old blankets and pillows and put the rectangular panel back on. I figure if I ever get stalled somewhere and it's cold out side, I have blankets and a pillow at the ready. Will change that eventually, I suppose. 

 

Will replace the fan with an electric one next. That's the big noise maker.

I used Dynamat on my floor - but it's certainly not what you would call "inexpensive" here in Oz. The rubber-backed foil insulation works well to reduce heat as well as noise. I think that I would be reluctant to use felt as it might store water and cause rust problems over long periods. A thicker rubber mat might work well too, but then I expect that you would pay dearly for thick rubber as well.

I started out using Eastwood's version of Dynamat on the roof and firewall.  As Desototoday said it was not cheap.  For the floor area I had a mat with a rubber backing.  Under the seat, and for the back of the cab, I went to Lowes and bought a roll of foil backed plastic insulation and used an industrial adhesive to secure it.  Every thing you do will help, but the biggest difference I found was when I installed my luan backed headliner and rear panels.  It's still not as quiet as a modern vehicle, but it's far ahead of what it was.   I kept all my cardboard patters and I'm planning on doing the same thing with the 2.5 tonner.  Mike

I used a product called USEAL. Its a foil backed asphalt based product for roofing. $16 a role at home depot. (6"x25'). It took about 5 or 6 roles to do the hole cab.

I think it has made a difference and I will eventually cover it all with more insulation and luan and some new door seals. The only problem is once you put the stuff on, its hard to get it off.

I think I will go to Lowes and see what  I can find. Where would you find that at Lowes? Maybe in the flooring/ carpet area.  I was cleaning out an old oldsmobile and pealed out some stuff that looked like roofing felt that was from the factory.  thanks noel in nm

I'd look in the roofing materials area for that stuff.

 

When I did my interior with the Quiet Rides kit, the kit had several strips of Dynamat and a "map" to show where to place the strips. They claim that you don't need to cover the entire panel to make a difference. The strips were placed in strategic places to reduce panel vibration, which leads to much of the noise. Then there was a layer of foil backed insulation to reduce heat transfer and reduce noise. I'm sure you could find some home improvement store substitute for that too.

I used Peal & Seal...got it at Home Depot or Lowes.

 

Read about it in my post here.  Made a big difference in the sound (and I didn't carry it up the front of the firewall because I don't have a trim panel there).   Later on, I wound up doing under the seat and the rear cab wall (up to just below the top of the seat) and that made a difference too.

So how does the stuff work out as far as putting it upside-down? for that matter, how does it hold up to wisconisin's wild weather changes?

[Merle Coggins]

I don't know about the Peal & Seal, but for mine they supplied Dynamat Extreme for the roof. (better glue?) Plus I have insulation glued over that and a headliner covering it all up. So I don't know if it's still stuck or not.

I watched a news clip this morning (May 13, 2013) and saw lake ice moving into houses in Wisconsin.

Don, it's a crazy continent we live on. If this were Europe the ice would be in another nation. It was 102 in the shade yesterday, just as hot today. Ice in WISC / Heat in Calif.

If I understand what I've read, basically the blocking high in the eastern Pacific that made California so hot and dry this last winter moved the storm tracks up, east and then down into the Midwest so they got all our usual moisture, chilled by its passage north. So the ice in Wisconsin is the flip side of the heat in California.

That's correct - you only need strips of the Dynamat to take the "tin can" out of the sheet metal. Foil-backed jute then can be laid over the entire area. The only place where I wouldn't use the jute would be inside the doors, and maybe the roof, where moisture can enter or condensation can collect.

Bedliner spray, styrofoam board insulation, marine grade vinyl upholstery. If it works on my VW with a rotted out muffler, it will more than suffice in a PH.

 

The floor of my 49 was covered with burlap sacks, cheap little woven rugs (think the loop kits that kids made pot holders out of), a layer of asbestos house siding shingles, and then a horse blanket. Worked pretty good, until it got soggy and the floor rotted.

John: I better get my blankets and pillows out of my doors before fall!  

 

John, I know. It was a spur of the moment thing sort of a "WHAT IF". It worked and I drove to the BBQ in a quiet cab. But they will be removed!  I may be tight but hopefully I'm not cheap and stupid.

Paul - might be a good idea. Water gets in from the window and will stay soaked up in all that bedding material, and do it's work on the sheet metal!
