[DeTomaso] cabin heat-A/C

[JJD1010 at aol.com]

Matt, there are components of both heat and sound that need to be  
attenuated. Here is sort of a primer to get you started. There are lots of  products 
out there and if you understand the properties you will get what you  need.
 
Heat
There are 3 types of heat.  1)Conductive Heat flows through a solid object 
from hot to cold. These need to  be blocked. 2)Convective Heat is heated 
airflow, usually  caused by air leaks into the car. These need to be sealed up. 
3)Radiant Heat is the flow of invisible infra-red rays  emitting from the 
surface of an object. These need reflective barriers.

(http://www.coolcarceramic.com/comparisons.htm)    Blocker and sealer for heat and sound.
I used this in my engine compartment and firewall, passenger  compartment 
and roof, front trunk, and under the car. I also  used a reflective barrier 
on the engine bay side of the firewall.

Sound
There are several types of sound control products. 1)Vibration Dampers  are 
used to eliminate or reduce structural resonance and vibration. 2)Sound  
Barriers are used to block and reflect high energy airborne sound like exhaust 
 and tire noise. 3)Sound Absorbers are primarily used to soak up mid band 
and  high frequency airborne sound and reflect thermal energy. 4)Gasketing 
Materials  are used to eliminate squeaks, rattles and buzzes and to seal 
speakers.

Go to product links further down the page to get good description of how  
the different kinds of sound control work. I used VB2HD on my doors and 
Dynamat  inside the doors.
