Anyone use this stuff as a substitute to Dynamatt?

it insulates well .i had some on the roof of the wag.

[brubakes]

I was going to use it in addition to a carpet kit with the mass backing. This would go basically anywhere I could fit it inside the cab.

I used it on my roof. It reduces the heat, but doesnt eliminate it.
That said, Id use it again. Was easy to install, I used dime sized dabs of grey silicone about 10" apart and hi-temp aluminum tape for the edges.

Yeah I used it to line the floor of my gladiator. spray the back with 3M Adhesive and use foil HVAC tape for the edges. Works awesome.

I have heard that a product called Peel & Seal works really well. Supposed to be able to get it at Lowe's (and I would guess Home Depot).

Comes in a roll and kinda looks like Dyna-Mat. Self sticking rubber back with foil face. Is actually a roof patching material.

I have been thinking of using in through out my Wagoneer to deaden sound and help insulate.

Just a thought.

How does it work for sound dampening? I was thinking of doing the same thing under the carpet and in the walls of the cargo area and maybe even behind the door panels.......

It looks like the same stuff they make sun shields for your windshield out of. I would use the Peel & Seal stuff personally.

Won't dampen sound at all; it's all air. The reflective surfaces and the bubbles are designed to reduce radiant heat transfer. This would be most effective to keep heat from coming in through a hot roof or where the exhaust system is close to the floor.

It is even more effective if you can keep it from touching the roof. To explain why would require a short course in the three types of heat transfer: radiant, conductive, convective. This stuff is good for radiant transfer because of the reflective surface and somewhat effective for conductive transfer because of the air bubbles.

To reduce noise you need mass, something heavy and thick.

I've used the peel 'n stick to try to reduce tire noise, but even after two layers I couldn't tell a difference. I may use the rest of the roll for another layer but I'm not optimistic.

Maybe I should be looking at a different product. I want something cheap that will help deaden sound and heat for my J20.

This stuff? Too bad its only 6" wide, that would take a lot of material.

[Chevelleguy]

Yep, that's the stuff. A member here has used it. I forget how many rolls it took to do his Wag, but he was happy with the results and it was cheaper than Dynamat. For your truck it should only take 3 rolls.

[brubakes]

I found this (http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=330351907257&viewitem=) stuff on EBay. 4'x10' for just over $40 shipped. Little more then the home depot stuff, but it is wider at 4' if which I think would help if you were doing large flat areas like a roof or cargo area.

I saw on Peel and Seal's web site they do offer the product in 100 sq. ft. cartons in roll widths of 3”, 4”, 6”, 9”, 12”, 18” and 36”.

I got a sample of the Low-E insulation sitting here - it looks like it'll work a heck of a lot better than the bubble wrap type stuff (i got it from this (http://www.lobucrod.com) site which looks to be the same people). I also went in to lowes yesterday to look at the peel and seal. That stuff looks a bit too thin to do anything.

[BamaDrew]

Low-E sounds good...never had heard of them before. Please let me know how it works for you because I will be needing to lay some insulation down before too long and DynaMat is crazy expensive!

[rocklaurence]

Insulating heat transfer like stated above is one aspect and this stuff doesnt list an R rating which leads me to believe its mostly for Ratiant heat. Any reflective mat would work the same. These products would reflect the heat back into the floor or roof not letting it dissipate. A daul material mat would be ideal. One that reflects and another that is a barrier.

[HOOT]

I was thinking of doing the peel n stick roofing stuff but put it on the outside of the cab at least on the firewall and underside. A piece in the doors,roof and rear of cab should work great. I have some nice sound deadening matt to use under the carpet.
I find I get alot of heat from the exhaust and motor transfering to the cab.

Something else has got me to wondering also. While cruising the diesel site I seen a cure for the heat from a heater core. This is a big prblem with the Ford's as the heater core is in the dash. There is a kit for $49 or so that shuts off your heater core flow while you have your AC on Max AC. They say it really helps the factory system keep the truck alot cooler.

So for the Jeeps I would think the same system would be great for keeping the heater core heat from coming into the cab. I don't have AC but figured it could be put on a toggle switch or something. I can't do without my defrosters living on the river. I drive home in some heavy fog half of the nights. Running heat against the inside windows helps keep them clearer. Running during the daytime in the summer can scorch you legs if sitting in the passengerside.
Sound feasible????

I just took a look at this stuff in person and I don't think it's what I am looking for.

[brubakes]

Has anyone ever used FatMat (http://motors.shop.ebay.com/__?_from=R40&_trksid=m39&_nkw=FatMat) or SCO Automotive Insulation (http://www.sportcompactonly.com/Insulation/Interior/part_c-106_pl-2611_p-1219.htm)? 4'x6' sheet for $20? Very economical if its worth a crap.

Why not just use the real deal? I used dynamat on my roof and was very happy with the results. Doors shut with a "thud" now instead of an echo - lol. Noticed immediate improvement in sound and temp, not to mention that it provides an extra barrier of protection from leaky roof grommets!

if you search ebay for "Dynamat Bulk Pack" you'll get all the material you need and then some for a little over $100. Well worth it IMHO.

With Dynamat its all about the high cost. If I can find it for cheap then I'm all for it. I don't doubt it does a hell of a job.

I searched eBay...thats a great price.

Didn't know that the extreme Dynamat is also for under hood applications.

I'm going to try it on under side of hood before hood insulation.

[brubakes]

anyone know how much sq ft the cab of a J20 is?
