Hi all,

.. I placed a hot clothes iron on the
outer wall and measured the temperature/rate of climb on the inner wall,
as well as the ambient temperature inside the cabinet. It was enough that,
even with a comparatively small heat source (well, to a garage fire,
anyway), anything within a few inches of the inner wall would have most
definitely been damaged, and possibly items close to the center after a
half-hour of exposure to the heat source.
Aaron asks: is there something anyone could recommend that would
make a good lining for the inner walls of the cabinet to insulate it from
heat?


Drywall/ sheetrock/ Gypsum Board. Clipped or cemented in place. Its common,
Its Flat, the Gypsum part wont flame. Its Fire rated.

The expanding foam is definately NOT what you want. Its chemical
composition provides fuel and oxygen to fire.

If you have voids to fill - Plaster?

OR High Density FiberGlass Panels as in Commercial Drop-Cieling Panel Tiles.
This stuff is densely pressed, (Often embossed with a pattern) The
Commercial grade panels are somewhat rigid - but also fire rated for close
proximity to commercial lighting. Note the stuff is pressed class fiber -
Not impregnated, bound, or laminated with epoxy or polyester resin. The
resins also support Flame with out need of too much oxygen.
