Best insulation?

What is the best sound and heat insulation for inside the car cabin/ roof etc.?? That foil bubble stuff the street rodders use is ridiculous.

Dynamat seems good for sound, but is outrageously expensive.

My 63 car has the old type suspended headliner, etc.

Has anybody used any of that foam type stuff?

Ductboard

s a suggestion you may want to look into a product called ductboard..it is a rigid fiberglass insulating board with an aluminum foil bakcing on one side and is use commonly by HVAC contractors for heating and cooling ducts..

Runs about 1/2" thick and can be cut to fit for the fire wall and floors..might even work in some cars behind the headliner.

just my suggestion.

I like the ridiculous bubble wrap! Just finished insulating my entire 53 Chevy truck cab with it and it works great. Two layers in the headliner and it is very effective. Can get a lifetime supply @ Home Depot for about $40.

my humorous reply, honest

Excellent, I am pleased that you are pleased.
As I indicated, I hate it, it's a waste of time, effort, and money. I wouldn't use it if it were free and YOU installed it in my car. I am serious about this, not sarcastic.

Dynamat type stuff is very expensive sound insulation and doesn't temperature insulate.

Fiberglass ductboard for heating systems has been banned for several years, but never sound insulated very well anyway.

tc33 that's a good link. thanks. $$$$$$$

Rigid foam would be like making a mozaic.

Maybe stripping Lincolns and Cadillacs in the junk yard is the thing to do...

Seriously, does anyone have any other ideas ??????

Has anyone tried that spray on ceramic stuff ??????

insulation

Try Peal & Seal that you can buy at Lowes in the roofing section. The stuff comes in rolls 6" x 25 ' I used it everywhere in the car,floors,roof, sides.
For added insulation and sound barrier you could add the two sided bubble wrap over it.
Hope this helps

I was looking at the foil bubble wrap yesterday at Home Depot. The salesperson suggested that one layer would be all that is required for heat insulation, but for sound deadening ,I should get something else.Any thoughts there? I am getting ready to insulate as well.I was wondering if the dense foam with vinyl face used to insulate and deaden sound in tractor cabs could be glued over top of the bubble wrap and be effective. Jim.

LizardSkin

There's this stuff called Lizardskin Ceramic insulation that looks interesting. It reduces noise by 10-12 decibels, which would mean the noise would be reduced by 1/2 since decibels are on a logarithmic scale. It reduces temperature by 25-30 degrees. Comes in 2 gallon buckets and can be sprayed or brushed on and cleans up with soap and water.

Never tried it. Here's a google search link for it: Click Here

Yep I want it as quiet as a Lincoln Town Car. I can live with another 50 pounds.

Heat, let's remember that a car firewall and engine heat going out under the floor (plus exhaust pipes) is a lot hotter than the outside air around a house. And think about that tin roof and all that greenhouse. And that hot summer air is moving 70 mph, that sucks the cool out of a car.

Did we ever realize that the average car has enough air conditioning for a modern 1500 square foot house??????

I'll look into the peel and seal. thanks

Tractor cab stuff glued to the metal.... that's an idea. I'll see how $$$.

Ya ceramic, what I asked about. $$$ ? Anybody ever used it?

I have even seen some felt-like stuff they put under those new laminate floating fake wood floors in houses. Several layers of that ???????
Factory Lincolns have 3/4 inch of felt in the floor.

I'd like to hear what someone has actually tried.

Home Depot sales people might be Auto Zone rejects.... lol.
Just parroting what they have been told, no practical knowledge.

Thanks guys, that is some good information.
