Yes; you=E2=80=99re right; Dynaliner is their best product for thermal issu=

When I was restoring my BJ8 (about 6-8 years ago) I tried to compare variou=
s thermal insulation efficiencies. 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do not publish this information.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 notic=
e that they seem to be saying Dynamat is primarily for sound insulation & t=
heir Dynaliner is primarily for thermal insulation. Remember that anything =
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. B=
y the way, it is the small air spaces that do most of the insulating, not t=
he rubber.
R values are often stated as btuh/inch. So, if something has an R value of =
8 btu/inch & the material is 1/2" thick it will actually have an R of 4.
This is primarily discussing conduction. Heat is transferred by conduction,=
convection & radiation.
The insulation in a Healey will have to be able to withstand relatively hig=
h temperatures, perhaps water & possibly some abrasion.
I am trying to point out that Dynamat appears to not be the best way to red=
uce heat if that is your goal & there is very limited space available for g=
ood thermal insulation so use the best available after you figure out what =
that is.

Bob,
Agree with other posts about replacing grommets, and sealing any gaps you f=
ind in the engine bay. Any opening will let heat in of course.
I didn=E2=80=99t use any caulking when I installed the tunnel; just the fac=
tory seals for the tunnel IIRC; But, it=E2=80=99s been awhile=E2=80=A6
As far as heat insulation, I used a product called Refletix; can=E2=80=99t =
say it reduced the heat any or not; it=E2=80=99s still hot in the footwell.=
I think if I were doing it today, I=E2=80=99d use Dynamat. I just put so=
me in another vehicle as sound insulation and it works great for that and i=
s supposed to reduce heat as well. I put the Refletix on the gearbox side =
of the tunnel as it=E2=80=99s rather thick, but I think I=E2=80=99d put Dyn=
amat on the inside. It=E2=80=99s very thin (but heavy), so I don=E2=80=99t=
think it would make the carpet look too thick. Not cheap, though. Alot=
of the custom car shops use it; Foose, Kindigit, etc.
BTW, Dynamat does make an entire kit for one of the big Healey=E2=80=99s; D=
on=E2=80=99t recall which one, but its on their website and should be a cus=
tom fit. Should work on all big Healey=E2=80=99s I would think.
I need to pull my tunnel off as well to replace the gearshift boot; may put=
some Dynamat in there as long as I have it off.
Hope this helps,
Frank
