I.E. "R" values. My primary concern was heat not sound. Many of the sources made it nearly impossible because they do not publish this information. I just looked at Dynamat's website & in a quick search could not find any "R" value information. However, I did notice that they seem to be saying Dynamat is primarily for sound insulation & their Dynaliner is primarily for thermal insulation. Remember that <b>anything</b> you put between the heat source & the cockpit will act as an insulator. But some things will be better at it than other things. Dynaliner is a closed cell (air spaces) rubber material. That sounds similar to neoprene to me. By the way, it is the small air spaces that do most of the insulating, not the rubber.<o:p></o:p></span></p></div><div><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial",sans-serif;color:black'>R values are often stated as btuh/inch.

I think if I were doing it today, I’d use Dynamat. I just put some in another vehicle as sound insulation and it works great for that and is supposed to reduce heat as well. I put the Refletix on the gearbox side of the tunnel as it’s rather thick, but I think I’d put Dynamat on the inside. It’s very thin (but heavy), so I don’t think it would make the carpet look too thick. Not cheap, though.
