[Healeys] Cockpit Insulating revisited

[Healey Bruce]

Dynamat is a good material when redoing an interior, but for someone who 
already has carpet fitted and the thickness of Dynamat would be a problem, I 
would like to suggest an alternative I found.  Fiberfrax is a ceramic cloth 
insulation, used commonly in aviation.  Pilots out there may be familiar 
with it.  It provides excellent insulating properties up to something like 
2000 degrees.  I have 1/2" thick batting "insulation" under my carpet, which 
basically provides zero heat insulation.  I put 1/16" Fiberfrax cloth under 
the batting, using 3M trim adhesive ("yellow snot") on the vertical surfaces 
of the foot well and 3 sides for bell housing area.  I also insulated the 
back side of the bell housing cover.  Because it is only 1/16", all the 
carpet snaps in no problem.  You buy it by the foot, 24" wide, which, 
coincidentally, is just about perfect for the foot wells and floor pan.  I 
bought it from Aircraft Spruce and Specialty 
(http://www.aircraftspruce.com/).  About $50 worth would do both sides.
