What are your results of insulating your transmission tunnel?

[2004Academy80]

I'm researching various products to insulate the radiated heat from the bare aluminium transmission tunnel (caused by heat soak in traffic).

The exposed foot well I will line with the CC kit in the engine bay.

I have new tunnel carpet, but now I need to decide what to insulate the cockpit side of the transmission tunnel with.

4 products options found so far;

thermo-tec-suppressor-heat-sound-mat

thermo-tec-thermo-guard-fr

thermo-tec-cool-it-insulating-mat

teknofibra-self-adhesive-heat-shield-mat

Does anyone have any experience, comment, knowledge of which will suppress the heat most efficiently?  or have any other product knowledge.

Thanks

p.s. I don't want to lag the exhaust primaries.

just the tunnel carpet has been enough for me,

warm but not hot

Where does the heat come from, and how does it get to the tunnel?

Thanks
