Interior Insulation
 
I have seen a lot of talk about how the best way to insulate the interior of the car but my question is do you really need to completely cover every square inch when using a product like second skin for sound deading? I have some of the glass balloons to use for heat but I am not sure if you put the second skin on first or after painting with the heat sheild. I also have some of the bubble wrap material that can be used instead of the micro balloons. Two many choices with every site telling you to use their products. I am going to use this in a 32 prostreet fibergalss body.

I am not sure of what you mean by glass balloons, but any way you can buy some pretty good insulation for about $25.00 with aluminum foil attached. I got some off of eBay and it made a huge difference in my '29. I attached it to the inside of the firewall and to the inside of the roof. Also I saw where you can use rug padding and the type that is used on cellar floors (water resistant) may also be used and it is fairly cheap and easily found.

Interior insulation.
 
Personally with my expierience insulating a car properly can be an investment. For a couple of bucks more you can't go past DYNAMAT. Cover your whole floor, firewall, roof and even door skins, theres different grades up 1/2 inch thick for the floor (which needs glueing with contact adhesive) and some thats 1/8 thick thats aluminum with a sticky backing (good for firewalls). it'll add a couple of pounds to your car but well worth it when cruising down the highway.

Check this thread for alternatives to the over priced brand name products.

just remember not to use the silver "bubble" type on the floor or trunk floor,this type can tend to lose air under even the repeated pressure of your feet-which makes it lose all of it's insulating properties! I like to use the self adhesive lead septum foil type on the floor (cool-tech,dynamat-ect...) and the cheap bubble type on the :quarter panels,inner door panels,and roof panels. Remember:any insulation will help better than none at all,but areas of high heat-firewall,floor above close mufflers,ect. will respond to an insulation with a reflective surface like foil-mylar, and an insulator like fiberglass or lead septum type.shop around,there are many different manufacturers making the same product and just pad printing their logo on it! And, don't spend the money on the "special" aluminum tape for the seams of the insulation on the self-adhesive type,just go to home depot and buy the aluminum foil duct tape for 1/3 the price! it' the same stuff! :thumbup:
