How much Dynaliner to use?
I'm insulating the enterior of my '73 BB coupe. I removed the dashboard, steering, heat/AC box, and all the old rubber firewall insulation. After a thorough cleaning, I have covered the floor and firewall with a layer of Dyamat, plus 1/4" thick Dynaliner. Before I begin the reassembly process, I want to make sure that 1/4" Dynaliner is enough to block the heat. Should I add another layer to the tunnel and firewall areas?
Thanks a lot,
John

Now I haven't done this myself but from previous threads I remember to really close up all the potential air leaks on the firewall. Any place where warm air can enter the cabin area.
I think I'd rather wrap the pipes and use some sort of heat shields under the floor boards rather then trying to block heat once it has penetrated the floor and firewall.

Do you currently have the factory heat shields in place?
I see alot of guys spend a considerable amount of money on expensive insulation for the interior without even considering using the "Low Tech" heat shields.
I have the factory shields in place on my '69 and only used 1 layer of Reflectix on the interior. My feet are always comfortable.
Be aware that too much of any material under the carpet may lead to fitment problems with the console and sills!

This project began as a simple "Replace the crappy wiring". Then one thing led to another and now I have 1/4" Dynaliner covering everything! I was able to cover lots of holes in the firewall which should reduce the heat gain significantly!
As far as the stock heat shields go, mine doesn't have any so I agree that would be a productive place to work on.
I am still wondering if 1/4" Dynaliner is enough to do the job on the inside.
Thanks,
John

I'm in the process of insulating the interior of my C2 with Dynamat and Dynapad.
Check out the Dynamat web site. In there, they suggest using Dynamat as a first layer, then on top of that, they use the Dynaliner. The combination of those two products provides great insulation quality.
Then, they suggest an improvement to the Dynamat and Dynaliner combination: replace the Dynaliner with Dynapad to obtain a maximum benefit.
Something else to consider: using Dynapad will attenuate the higher noise frequencies, but not the lower frequencies. This means the lower frequency noise will become more noticeable and apparent.
I'm not only improving the insulating quality of my interior, but also reducing road noise and enhancing the interior audio acoustics so as to achieve a much better music listening environment.
Dynapad is expensive. I'm trying to determine if the added expense over Dynaliner is worth the money.
If you decide to go with Dynapad rather than Dynaliner, please post your reasons ... I'd certainly be interested to learn your decision criteria.
Best Regards,
Jay

Jay,
I've already covered the inside, first with Dynamat, then 1/4" thick Dynaliner. So trying the Dynapad is not an option anymore.
I am trying to learn what other guys have done and what thickness they used.
Good luck on your insulation project!

If you happen to learn more of what other guys are doing or have done, I'd truly appreciate any suggestions and improvements by way of a PM or Carrier Pigeon ...
I've actually not purchased the Dynaliner or Dynapad product ... waiting for more conclusive information
.My resto mod project began by only refurbishing the front suspension, steering components and conversion from front brake drums over to front disc brakes. But, the dreaded CFS (Creeping Feature Syndrome) overpowered my IBB (Iitty Bitty Brain) and, so far, has easily delayed completion of my project by more than a year or more
.You may wish to do a file search over on the C1/C2 Forum. There are bits and pieces of information per your subject. Also, learning contact names for further clarification as to what they did has worked for me
.Best Regards,
Jay
