[TheForge] temporary heat shield

[ries]

I am unclear from your description what you really need- If the piece  
is staying on a ship, at sea, then stainless is probably the way to go.

Both aluminum and stainless are available in various degrees of polish.
This is not a standard item that is stocked in every small town metal  
distributor, though.

And you pay extra for the shiny finish.

I often order stainless sheet from Alaskan Copper and Brass- they are  
one of the largest non-ferrous distributors in the whole west.
They probably have aluminum in a shiny polish as well.

If all you need is a temporary heat shield, I use fireproof blankets  
from the welding supply store for on site welding where there could be  
damage to surrounding materials. Cheap, and re-usable indefinitely.

hello;

i am in need of a temporary heat shield and seeking some advice and
suggestions.

for peace of mind i would like two heat shields spaced one each a part
with ceramic standoffs. the question is which is the better sheet metals
to use for the heat shields.

highly polished aluminium would be the first choice since it would
reflect the unwanted heat , lightweight, and low in cost.

where would i be able to obtain 2 sheets of 4x8 highly polished
aluminum?

highly polished chromium steel would be the last choice since it would
refleact the unwanted heat at the trade offs of increased weight and
cost.

where would i be able to obtain 2 sheets of 4x8 highly polished
chromium steel?

the metal heat shield is temporary until we are able to construct a
warming tile heat shield later in the year.

the metal will not be exposed to salt air/ocean air/open seas air for
that long of time so i am not worried about corrosion.

poor ascii art below.

   ================================= <-- metal deck

        l -- 1st heat shield 1 inch above the deck and 1 inch from the
             wooden frame bulkhead.

        i -- 2nd heat shield 1 inch above the deck and 1 inch from the
             1st heat shield.

        the gap between the stove and the 2nd heat shield will be 12
        inches.
