Dynomat question

[Mad4slalom]

Hi all , with the hotter weather I am noticing a lot more cabin heat soak. Anyone stripped out seats carpets , console etc o retro fit a heat barrier? If so , how much of a pita job was it, what is best to use and were the results very noticeable , oh and what did the product cost ?
Many TiA

I'm interested to know too, as I'm contemplating doing the same. Probably won't, but still an idea.

Ditto - mine will be like sitting in a blast furnace in this weather!

Nor used it myself but remember a Wheeler Dealers episode where Ed China fitted it to a fifties Chevy pick up truck. They were more interested in noise suppression and Ed did a before and after test with a decibel meter and it seemed to be very effective.

There should be quite a lot of reflective fibreglass barrier on the outside of the floor, tunnel, firewall as well as heat shields in the C3. I’ve replaced mine with self adhesive barrier.

Dynomat in my view is a vibration/NVH barrier and not the best for heat shielding.

In my Side pipe 65 coupe .....I used 2mm foil backed Peacemat and 15mm Jute with rubber coating ..Stuck the Peacemat on every surface ...even the roof ...then stuck the jute to it with contact adhesive..before fitting the carpets ..Have a look at the u tube clip attached ..

I realigned the out side of the tunnel and outside of the floor...made a massive difference to the cabin noise level and heat soak ...

From an OEM stock heat insulation perspective - on a C3 (especially a big block) the foam collar that squeezes inbetween the bellhousing and transmission tunnel/firewall looked perhaps something of an afterthought by GM to reduce the amount of engine heat being 'drawn' under the tunnel and creating further heat issues re. heating-up shifter linkage and the cabin surface of the entire transmission tunnel. Often degraded and lost.....it seemed to do it job well.

Ah ok, it was just a name I had heard and presumed it was for heat.

That is as clean as a pin and a credit to you !

Dynomat was the stuff they used in the previously mentioned wheeler dealers episode with the 50’s pick up. Ed’s china put it in mainly for the cabin noise. Those early trucks were for work, you just put up with the noise.
God forbid if you see an exposed screw head nowadays
