Hello all,

I was wondering what the consensus of the forum was for insulation. After reading through several old threads I couldn't really make up my mind on which is the best, since several are recommended. Any suggestions?

Thanks,

Dexter

I have been using insulation from J C Whitney for several years on various cars that I have renovated. I put it through out the car. I particularly like using on the underside of the hood. Engine heat can ruin a good paint job. The insulation I use has foil on one side and a chopped fiber on the other side.

Have not done mine yet. Seems like most are not using Dyna Mat since it is somewhat pricey. Eastwood claims their product is just as good if not better for almost half the price. Some guys use stuff purchased at big box stores. I may go with the Eastwood product when the time comes.

been researching this myself and I will be going with "thermozite" double sided .applied with spray adhesive and a roller... cut and fit as needed.. I think it will work fine for me

The only thing that makes me hesitate from buying the insulation from Eastwood is that here in Phoenix,AZ where the high for the week is 104 F. it might melt over the summer. I have read several reviews of this happening over 90F. Has anyone here on the forum had this happen to them?

I think I might have to go with Dynamat. It isn't that much more expensive than Eastwood.

I found this: http://store.secondskinaudio.com/firewa ... l-barrier/

I was thinking that a liquid insulation would work better than a mat since with a mat there is a chance that water might get trapped under it. I am probably wrong since this is all new to me. But any ideas? It is also cheaper than dynmat.

Or these?:

looks like it would work for easy application and sound.... keeping out the heat does not seem to be one of the strong points of the product .although heat from engine and tranny may be air conditioning for you some days .. also I wonder what the added weight would be compared to some type of mat product ..anything worth killing is worth overkilling so sludge at 4mm thick would add up quick ... not sure I would worry about trapped water either ... mine is a daily driver and so near the foothills to the mountains things change quickly I get caught on occasion in the rain and snow with the top down .... day or 2 of sunny weather and car seems to dry up pretty quick ..betting Arizona would do the trick even quicker

dbr, you're worried about getting water trapped in Phoenix?

Yes, I suppose you are right. After tearing up all the tar and cleaning it all up I don't want to have to do it again for a long time!

I finally went with Fatmat. Reasonable price and no reviews of melting. So we'll see!

Thunderstorms?

I have laid new flooring this weekend along with many other tasks. I installed ezcool and found it easy to work with. I started with almost a full roll being 4x10 and came up short by about 4 square feet. I got what a friend had left over after adding to his T A so I"M not sure what I started with.


I have ordered another roll to finish it out insulating places that where not done in 78. Some places I will double up. Maybe overkill but will do so anyway.

I put Fatmat down first (it's cheaper than Dynamat and others), then I put down the foil faced (both sides). Fatmat is a sound deadener and the foil faced is a heat barrier. I did this on my 1955 Chevy restoration recently and it works well.

I'm installing heat and sound insulation for the firewall and transmission house. I'm covering the rest of the car with a sound control mat. Both of which I bought from LMC Truck. It is a place I regularly go through for my GMC. The sound mat is a bit pricey. I bought the 10 sheet package and the 4x6' roll. I matted the whole cockpit with 6 1/2 sheets with over lay and I haven't cut the insulation yet but there should be plenty left over for under the hood. I am still restoring so I don't know how great the products are yet.. I will let everyone know

multi-purpose heat and sound 4x6' = $30
sound matting 10 sheets = $170

I've been led to understand that applying the insulation/sound-deadening material inside doors make them close with a much more satisfying sound than as they are without. Anyone used that kind of material in the doors?
