240z interior insulation

[wa5ngp]

In order to help the marginal ac performance I am considering applying some insulation under the carpet and wherever I find any dead space between the interior parts and the body. Anyone have a recommended source for this kind of stuff? I bought something like this from JC whitney before but I'm assuming that there's someone that sells this stuff in bulk for a better price.

If not then I'll just see what google finds.

I bought a roll of the insulation from JC Whitney. It is OK for noise supression. It will attract any moisture you might encounter, however. It has the foil cover on one side and fabric on the other. I put it under the dash and under the seats. I guess the it would be OK for heat. I know these little babies are HOT in the summer. Just roll down the windows and think you are back in the 70's! Whooha!

Various articles in the archives.

Here's one that I contributed to that does a good job of summarizing everything.

There's a bunch more, use the Advanced Search Function and plug words in until you find information.

Hope it helps

You can always try B-quiet brand for suppression of noise and heat. This is what I am going with and many others have used with good sucess. I assume since it helps to reflex heat it would also help in keeping the inside cold (the noise damping matterial is rubber based. It's more expensive than other methods (but the best price on it's type of material I can find), but is also much thinner and works well.

If you are going for cheap, the generic JC stuff you are looking at is the best method I have seen. Just use froogle.com or other price checking sites to look for the best price around.
