Interior Insulation


Recommended Posts

Several members have posted about a generic type of Dynamat insulation in their cabs. It has a rubberized layer backed by foil and is self-adhesive. They said they bought it at either Lowes or Home Depot, but no one at my local stores has heard of it.

Does anyone have a brand name for the insulation or know what its original use is?

I'm getting ready to trial fit my interior and would like to put this in before the carpet, door panels and trim goes in.

Take a good long read on this site: http://www.sounddead...i-bin/index.cgi

 

Years ago, before this fellow started selling sound insulation he did tests of various sound deadening materials, including roofing material. Roofing material turned out terrible. DynaMat was pricy and not the best stuff. I would use the site for education and then look for local sources. But I live in San Diego and not far from Los Angeles, so I can find just about anything on any given Saturday or Sunday. In a "rural" area buying specialty items is much more difficult unless you do mail order.

 

Here is another interesting source for sound deadening information that does not sell anything: http://www.myturbodi...roofing-car.htm

Not for a Comanche, but good information and pictures.

 

Just found this thread for what it may be worth: http://www.soundsolutionsaudio.com/forum/topic/53026-second-skin-vs-sound-deadener-showdown/

Are you looking for JUST this isulation or asking what kind/brand would be best?

 

FWIW this is where i got mine, http://www.lobucrod.com/ reasonably priced and seems like good material. I have yet to install it to see if it actually works but i have high hopes. My only complaint is that it it VERY thin. To compensate i will be going to a junkyard to pull out some batting to give it a little extra bulk.

MJ had whole interior out when I bought it. Now the back panel, headliner and any empty pillar space that I could stuff it in to has regular old fiberglass household insulation. The floor has the usual batting, foil clad bubble wrap, vinyl mat and finally carpet. When I slam the doors it sound like a Mercedes.

 

Really the only noise that bothers me is the exhaust leak at the donut (a little annoying and soon to be fixed) and the muffler which has a golf ball size hole in it. Since it's not a daily driver I am constantly procrastinating on fix.

First time i have ever tried this, i think it turned out pretty good. Insullation, batting, new carpet. Havent gotten to drive it yet but on a real windy day its near silent in the cab, doors shut and windows up

This is what I did.

 

 

 

I haven't been spending as much time on my MJ as I would have wanted in the past couple of weeks. Some turmoil here at home and now the flu have slowed me down. Here's a run down of my current progress to date. Beware on the pics I haven't posted in a while. biggrin.png

 

I've continued on with the insulation. Behind the seat

 

 

the B pillars

 

 

And finished the seams off with some foil duct tape

 

 

 

 

 

For the floor pans I used a waterproof self adhesive flashing I picked up at Lowe's (thanks woodkrawler) for about $15 a roll.

 

 

Ended up using about 4 rolls. Started on the right side.

 

 

and finally the right side finished.

 

 

I finally had to force myself to face the damage from my jackstand miscue last fall. Surprisingly I caught a huge break on the repair. One good whack from my #10 dead-blow hammer undid about 90% of the damage. A little seam sealer.

 

 

and a coat of bed liner and it's good as new.

 

 

Well almost. Continuing with the insulation, left side.

 

 

More left.

 

 

Starting the trans hump.

 

 

I vacuumed and lightly cleaned the floor with alcohol before I started, and there's no way this stuff is coming up without a fight.

 

 

Finally finished. I'm pretty pleased with the results.

ftpiercecracker1 and Butchershop - I really like how that looks installed and will probably go that way. The website is apparently being upgraded so I can't get any info on the material. What size roll does it come in and how much does it cost?

 

I've almost finished my floor and cab work (have the dash out to replace the heater core) and would like to get insulation installed before putting the interior back in the truck.

can't seem to remember right now, but one roll is enough to do the entire interior in one layer. Floor, Ceiling, back, and a little on the doors. can't remember the price, had to be reasonable otherwise i would not have bought it. :D

Here's the info that came with the rolls. I bought two 4x10 rolls. Took me more than one roll for the interior. And I plan to put some under the hood, too.

 

Think it was about $40 per roll.

I used Permatex 27828 (Headliner & Carpet Adhesive) for placing it. Sprayed the truck and the material. Let sit 5 mins and put them together. Not so aggressive it couldn't be moved and refitted but the final hold seems very good.

Thanks. I wondered if it was EZ Cool. That's what I saw in one of the earlier posts but couldn't remember the name. How long did it take you to do the interior? Did you use masking tape, etc when you sprayed the adhesive? From what you and ftpiercecracker1 posted it doesn't sound very hard to do.

BTW - did you sell the wheels?

It's not difficult at all. Took me a full afternoon as I was fairly methodical - made a couple of templates from cardboard and test fitted some pieces before I cut them out.

I had some aluminum duct tape in the box so I used that on the seams. But any wide aggressive tape will work (not masking).

 

PM me your address and I'll drop a scrap piece of EZCool in an envelope and mail to you.

 

Yes, the wheels sold in an hour.
