Door sound proofing.... Wow

[RonD]

I did the Dynamat a year ago, both to the inner, and outer door panels, plus the complete floor, it really helps

 

[GMercurio]

I did my 06 with that stuff.



Wait till the hot weather comes. It smells to high heaven and it took over a month for it to go away.



Could not drive with the windows closed. The asphalt smell was overwheming. I also did the insides of the doors.



I did my 01 gasser too. Did that with Dynamat type product. It was worth extra money to me. NO SMELL.



I do live in a very hot climate though.

So,

I was bored the other day and wanted to tinker around on the rig. I remembered a product called Dynamat sound absorber / deadener. They use it on cars with high power sound systems to deaden and tighten up the sound. Anyways, Dynamat cost an arm and a leg. . About $80 to $90 each door on our Dodge rigs. Well, Some searching and googling got me sorted properly. Dynamat is the EXACT SAME product as the Peel & Seal type foil backed weather proofing stuff found an your local hardware store, It's in a roll and usually 6" x 25ft. Heavy foil on the top with about 2 to 3mm of black tar like rubber in the middle and strong adhesive on the backside. A trip to Home Depot and $16. 99 later I have a roll of it and my front door panels off the new rig. I peeled the factory plastic sheet halfway up the door and laid the peel and seal, overlapping it by about 3/4" and rolling the flat sections with a veneer roller... . Stuck the factory liner back down and then did the upper half. All in all it was about 45 minutes on each door. The difference is night and day! The door has a nice solid feel and sound when you close it, The speakers sound 100% better... Much tighter with solid bass (Factory Infinity system), The road noise is 30% less... My 35"s go waa waa waa waa while going down the freeway but now you mostly hear them through the firewall and not the doors. This weekend I am going to do the rear doors, I'll take some pictures and post them up. It took almost a roll to do both fronts, Left me with about 3 feet extra which I am sure the rear doors will need on the new mega. 2 Rolls peel & seal $34... ... Enough Dynamat to do the same job... . $320 to $360!!!

I have a Dynamat scrape in the shop with some sill/window sealer and I would like for someone to find the difference between the two of them. One is much cheaper and the other is, well expensive. Very good write up and pictures.

I have been wanting to do this for some time to my 2nd gen but have been hesitant to spend the money on dynamat. I have heard of this product from home depot from other forums and they all seem to believe it is the same stuff, or very similar. If there really is a smell for a short time, i am willing to deal with it considereing the cost difference. Thanks for all the info, now i cant wait to tear mine apart and do this. I plan on doing the doors, entire floor, firewall and roof. Mine is a regular cab so it shouldn't take nearly as much material as a megacab. I will likely put multiple layers in some places. I know the stacks are not helping my noise problem at all, but i like it loud on the outside and quiet on the inside. We will see if its possible.

I bought a 33 ft roll from Menards and did all four doors as the author R. Taylor did on his and the difference is quite noticeable. The road noise is a substantial drop. The 33ft roll cost me $17. 89 plus tax. This was a great idea for an affordable alternative. Good job R. Taylor.

 

[Kday]

As I live in S. Fl will this stuff smell like a roofing truck come summer? Sounds like a good idea but I'm concerned with the smell.

 

[R.Taylor]

So far it's been working great, Slight smell at first but now it's not noticeable. We've had a few warm days here since I completed it. There really isn't much of the actual surface of the black stuff exposed as most is stuck down to the door.

 

[SWithrow]

I placed the tape inside the door (aginst the outer shell) went top to bottom on all 4 doors and also removed the back seat and did from the back window down to the floor. Big difference in road noise. Took a little more time to do the doors but well worth the extra effort.

Now that spring is here I'm going to get my truck done. RTaylor I noticed you covered up the large openings in the door panels, while having holes allow noise to come through I don't think I'm going to cover mine. If I get creative I may make some kind of removable filler panels to cover the holes that can be removed with a couple sheet metal screws, then cover those with the material. I have a club cab, I hear taking the back seat panels out is a real picnic. Going to go after it and do it all at once.

My biggest concern is summer heat, gets into the triple digits pretty often, guess we'll find out!

 

[R.Taylor]

I'm still pleased with my inexpensive alternative. It does what I want it to do, quiet down the road noise that's transmitted through the doors and make the stereo sound better. Yes, at first there was slight smell but now it's gone... . I've had my truck in some hot environment but then at the same time I leave my windows and rear slider cracked about a 1/2", No need to bake my interior. I've checked it a few times and none it it has budged or slid down as some have said. If it came down to removing it it's no big deal, A heat gun, Plastic scraper and some acetone and it's gone... Just as much work to remove dynamat or any other sticky substance from a surface. I've your replies as well as a new post today. Kudos to the jobs you've done but I personally do not need my truck to be as quiet at a Lexus inside. I also wanted a cheap fix cause I'd rather spend the money on say... A full pillar of ISSPRO gauges or water/meth injection system. Dynamat = $$$ Foam/CLD Tiles = $$$$ ATP = $$$$$$, El Cheapo = $17. It's all a personal preference, How quiet do I want my CTD. Once again, Good job on your own methods and materials, The ATP stuff looks impressive if you want to get really quiet.

Hey man, I really think that's great. There isn't anything wrong with what you've done, especially if it accomplished what you set out to do. Each person has their goals and they select the techniques and materials based on those goals. Please don't think I was trying to be belittling with my write-up. I have just completed several big products on my truck and wanted to document them for the posterity of the forum and learning of its membership. You like rock, I like country... doesn't matter. Hard to beat it for the money and your goals.



And there's no way I am doing that ATP stuff.

Not all, I did not even think you were trying to connect one's job from another's. Good work on your job, Quite an undertaking but the results are what you wanted.



Cheers, R. Taylor

Good. I am not real big on trying to one-up anybody and would feel awful if that's the perception I portrayed.

 

[R.Taylor]

Well, It's almost been a year now and I am still very pleased with my low cost results. There is no smell what so ever as it was gone after the first month, We've had 3 days of 100 to 106 degree weather, no asphalt smell or goo dripping off the bottoms of the doors. I took a door panel off to inspect it, No sagging, running or melting. It's still exactly where it was stuck on.

 

[Prairie Dog]

I'll be taking my door panel off pretty soon to fix the power window switch and I think I'll try the low-cost option.

You don't have to take the panel off. The whole assy pops out the top.

 

[Shadrach]

What about putting the stuff on the back of the door trim panel itself? It would make it easier to access thing inside the door when needed. Shadrach

 

[Walker1]

Heck, I was thinking of putting it behind the rear seat.

 

[SWithrow]

Did mine in January...

I placed the tape inside the door (aginst the outer shell) went top to bottom on all 4 doors and also removed the back seat and did from the back window down to the floor. Big difference in road noise. Took a little more time to do the doors but well worth the extra effort.

I stopped at Home Depot. Couldn't get myself to buy the aluminum covered asphalt flashing, after I opened the package and got a whiff. It reminded me of the days as a kid when my family always got their vehicles rustproofed with that thick nasty sprayed stuff. We would smell it year after year on really hot days. Then I got to thinking, I'll get a roll of aluminum tape to seal off all the exposed edges hoping to reduce the smell. I went to the heating/cooling ducting section to look at the aluminum tape and on the shelf were rolls of 6" wide x 75' long Butyl Flashing that is 20mil thick. I bought two rolls of this and am going to dbl layer it. I have done the drivers door and already can tell the difference. Can't wait to get the other doors and back wall done. I'll reply back when I am finished after this weekend.
