it's like $15.00 a roll at the home depot by me!!!! has anyone ever used it???

Yup nothing wrong with duct wrap, thats what I used except mine is like a foil backed bubble wrap w/no adhesive.

[68X426]

has anyone ever used it???

Yeah, I use it ... .. . . . . ... .. for ducts!

Seriously, I think that it will be adequate for heat blocking, but I doubt there is any sound deadening value. The stuff is light and "pourous". Like cotton candy.

Just a thought: once you install it, do you really want to re-do it when/if it proves too loud?

HAHAHA LMFAO!!! nice!!! lol

hey BAD... what stuff did you use?!?!

im just trying to find a nice cheap alternative to all the expen$ive $tuff.... lol
OPPPPS sorrry troy..... 

[1BAD68]

I dont remember the brand or specific name but it was at Home Depot and was for wrapping ductwork.
It looks like an industrial bubble wrap with a foil backing.
Went with this because it had no adhesive and I layed it on the entire floor pan before putting the carpet down.
It keeps heat out of the car and really helped with noise. I will be using it behind my door panels when I have some money for new panels.

[HITMAN 149]

HMMMMM? 
do you have any pics of what it looked like?!?! i'll go scope it out.....
thanks!!

[moparjohn]

I don't know if it is "cheap" enough-Eastwoods has a knock off Dynamat now, with the foil backing, it's thermo-coustic, 33.75 square feet for $149.99.  It was enough to do the passenger compartment floors in my 69 T&C wagon, product code 12117- phone800-345-1178. MPJ

[1BAD68]

I found it, its called "Reflectix"
Its cheap but does the job and can be removed easy if you dont like it and want to spend big$ on Dynamat or something

[HITMAN 149]

cooool! thanks!!! i'll have to scope it out!!!!!!!

[oldcarnut]

I think that's the same stuff from Lowes I used in the wife's 68 Firebird.  Can't find the pics of when I put it in but I'll take a peek at it this  weekend to see how it's been holding up since I put it in a good while back.

Check out adhesive roofing membrane for sound deadening while your there. 

[HITMAN 149]

cool thanks guys fot the ideas!!! i'll have to head over to lowes & the depot!!!

[Patronus]

I used that bubble insulation too  conforms nice, tape the seams and your done....oh, Home Depot carries it too (by the insulation)

[HITMAN 149]

thanks bro... yea i have bothe lowes & depot right by me.. gonna scope out the better price!!!!

[HITMAN 149]

well i got 6 rolls yesterday at lowes for $15/roll... i got a small roller, a couple rolls of duct tape & a utility knife!!!! lmfao
so i'll let ya know how it turns out when i get my car back from the shop.. i'll work on it in the garage w my buddy!!!!

[b5blue]

Good Luck Hitman!

One word: eDead 80.

Thicker than Dynamat, & cheaper as well. Foil backed butyl sheet, just like Dynamat. It just doesn't have "Dynamat" printed all over it.
I got it directly from them online. I ordered 3 rolls, did the entire inside of the '69, inside the doors, and inside the 1/4's. Still have a roll left over, & will probably use it under the rear seat above the mufflers on the '68. The '68 has Flowmasters, and the drone inside the car is loud at times.
With eDead 80, the '69 is nice & quiet inside.

[HITMAN 149]

hey bill...
yea but im reallly on a budget for now... and im sure you read my wonderful thread from what happend last week at the shop... ugggg so now im trying to get the car driveable to take to the show on sunday!?!?! frankie's helping me out big time!!!

[694spdRT]

Check out adhesive roofing membrane for sound deadening while your there. 

I think I will be using Grace Ice and Water shield that is used up here is snow country. I would use one that doesn't have any granuals on it. It is self adhesive on one side and smooth on the other.

Cost at Lowes is about $70 for 108 sq. ft. that is 40mils thick.

thanks!!!!!!

Yes, in fact I'm doing my car right now with it.  Same stuff from Home Depot! 2 rolls will do mine nicely - I paid $13 each. 
I've seen the Dynomat or interior stuff for $75-90 on EBay.  This is not one sheet but is the same stuff and WAY cheaper.  And one foot wide makes it easier to apply imho.  Sticky on one side and foil on the other. 
I'm not done yet but if anyone is interested in pics, I can take some tonight.

[HITMAN 149]

yessss of course we want pics!!!!!!!!!! lol

[ODZKing]

Eh, should have known the answer to that from our first gen forum.
The only other expense was I purchased a roll of aluminum tape to cover the seams.  BTW, I checkedthe price ... it was $16 at my HD.

[HITMAN 149]

hey king...
which stuff is that?? the bubble inside stuff OR the insulation type inside stuff?!?!?
looks nice!! good job!!

[ODZKing]

Same stuff.  Plus one roll of tape. I think it must have been on sale when I got it.  2x13=$26 + 7 =$33 total.  It's gone up to $16 now but still ... way cheaper than Dynamat and easy to install.
I used the tape to insure the cut edges wouldn't curl under the carpet.

[694spdRT]

Don't you need "mass" to dampen vibration?  How much does that bubble stuff weigh.

[HITMAN 149]

not so much to dampen "vibration" as its more to insulate from the heat.. and noise... NO??

[694spdRT]

I guess vibration/noise is what I am talking about. I think a butyl or ashpalt material topped of by some type of insulation will correct a lot of the noise.  If you knock on a panel and it sounds "tinny" don't you need a product applied to it that has mass to first damper or reduce the vibration in the panel itself? I think the stuff you guys are talking about would probably work very well over a butyl or ashpalt based product for insulation. I just don't see it stopping much vibration in the panel. It is definately better than nothing. 

[ODZKing]

Exactly.
I'm not sure what bubble stuff you refer to 694spdRT, but the stuff I used is an 1/8 thick and more like a pad.  Weighs very little (as the entire roll didn't weigh 1lb) as pictured.
Noise and heat was what I was after.  My wife would put her water bottle on the floor and later complain that it was very warm.  Hopefully this'll take care of that.

I thought that reflectex stuff was some type of air bubble insulation. I have seen something like that had the reflective layer on it. If it is a high density foam that will probably work pretty good. I was reading up on Ice and Water shield and it seems that is what some guys are using for big stereo setups. One thread had a very lively debate but it appears very similar to Dynomat, eDead, etc. without the foil layer.  I think the roll I was looking at weighs about 26 lbs for around 108 sq. ft.

[ODZKing]

26 lbs for around 108 sq. ft.

Wow!  That'll take a second or two off the quarter eh?

HAHAHAHA LMFAO!!! YEA... that's not cool!!! lol
694spdRT.... yea i understand what your talkin about needing some mass/weight.... but im on a tight budget right now!!! lol that other stuff is a lil tooo much coin to drop right now.... uggg  lol
i got wire looms at lowes today... much more and cheaper than the auto store!!! hahaha hey every lil bit helps!!

The stuff I am talking about is around $70 for 108 sq ft.  I guess if you use all of it you might need to go on a diet for drag racing.

[plum500]

Old thread... but I have been having a time deciding/finding alternatives to insulate... little bit for noise on the roof, and heat everywhere else... anyhow, for anyone else in Canada, while Home Depot doesn't appear to carry the Frost King stuff, Lowes does...

https://www.lowes.ca/metal-duct/frost-king-self-adhesive-foil-and-foam-duct-insulation_g1194726.html

Whoops, that's the foam stuff... THIS is the fiberglass stuff..

[ODZKing]

Foam and foil is what I used on both cars. Worked great

[oldcarnut]

I used the bubble wrap and foil

Also sprayed some sound deadener under it
