Interior Insulation

[jhorton3]

I've been kind of disappointed with the felt/aluminum topped insulation I got from Pep Boys, and wanted to know what else is out there and being used on our cars. I'd like to redo what I installed and get it ready for an interior (hopefully sometime in the Fall).

Dynamat comes to mind, it's a popular method for sound deadening and insulation.

There are others. Most importantly, though, be sure to use a material that's fire resistant! You don't want flammable material under your bum, especially in an LBC.

Anyone else?

I think I am going to try this stuff once I get to the level where gutting the interior will not keep me from enjoying the car. The mod my brother and I did for the return trip from LOTO did help some on the heat in the interior but it was a temporary/quick/el cheapo job.

I bought some foil faced stuff from Aircraft Spruce. Meant to be used on small aircraft firewalls. It wasn't real cheap, but it works great.

Probably going to use this stuff on the poly Spitfire tunnel I got from TRF.

I've heard of people using asphalt flashing from Lowes or Home Depot on their interiors. It comes in a roll, and is adhesive on one side.

It sounds heavy...

Wouldn't it smell like pavement when it's hot?

Pavement. The new aftershave for men who like men things like cars and stuff.

Available at Walgreens.

I have used this in one of my other cars
and they are having a summer sale.

Real easy to cut with scissors. Peel the backing off and the material sticks and molds to any shape you cover very well.

Here is what I was talking about. I have heard it is very similar to the original Dynamat... https://www.lowes.com/lowes/lkn?action=productDetail&productId=154017-81326-PS625&lpage=none

How do you think the Lowes stuff would work for under my hood? Peel off?

I would not use this. It's flashing, meant for roofing/chimneys.

If you're looking for something fairly inexpensive, the b-quiet is about half the price of Dynamat, but much better (IMHO) than trying to adapt a roofing product.

I work in construction and I've worked with plenty of that asphalt flashing. Although I haven't worked with the aluminum-faced stuff, I'm guessing the asphalt part would still be the same. I would not put it under my hood since the stuff I've worked with loses most of its stickiness in cold temperatures. I would be worried that the stuff would fall off on top of the engine on a cold winter day. If the engine was started with this stuff on top of it you would soon have a very sticky mess. According to the reviews I've read, the asphalt based sound dampening stuff is basically the same material as the weather shield stuff and performs about the same too. It's also heavier than most other sound dampening materials.

I wouldn't want to use an asphalt product under the hood as it is heat sensitive.
For the interior guyes over at the Mustang site I frequent there is a recommendation for "Frost King Duct Insulation Self Adhesive Foil and Foam".
Available at Loews. Just throwing out an alternative to the cheap asphalt stuff and the very expensive car specific stuff. Since I haven't tried FrostKing myself, I'm not making a recommendation.

 

[tosoutherncars]

yes... if you're looking for something for the hood, go to a junkyard and find yourself an old '80s Mercedes, particularly a diesel. They all had a sound-deadening pad on the underside of the hood that is big enough, and (obviously) rated for such use. Cut, spray w. adhesive and away you go.

Or buy a new one I suppose, but I have no idea what they go for.

once u stick that roof flashing on
its there forever!!!
try taking a window out of a house
once u put that stuff on!!
i wouldnt get it near my car though......z

If you are trying to cut the heat from coming up thru the floor the best (and lightest and cheapest) answer that I know is to attach a sheet of thin steel to the top of the exhaust pipe (I used 3 muffler clamps to hold a 3" x 48" piece of steel to the the pipe). It cut the heat so much on the trip to LOTO and back that only the heat that came thru the shifter hole was obnoxious! .
Makes a BIG difference for the floor!
