wood stove or electric aside
would the thermous method keep in more heat?
I saw reflective insulation too
That is called a "radiant barrier" and is mostly effective as to prevent solar radiation from heating attics...you have to have at least an inch void between the radiant barrier and the space you are seeking to protect. Difficult to achieve in walls...In attics it takes one of two forms:
1) A paint that has a metallic content that reflects infrared and you apply it to the underneath of roofing decks...this is the easiest to do but is not nearly as effective as the second method.
2) An aluminum foil radiant barrier usually stapled
shiny side down between the roofing joists…The reason it is stapled shiny side down is that if dust were to collect on the shiny side, it’s effectiveness would diminish…It doesn’t matter to the reflective qualities of the foil to infrared if the shiny side is down, it still reflects it back into space.
Oh…you get specially manufactured foil from roofing supply house for this…don’t try to use household aluminum foil.
One more thing…it’s not effective in preventing the transfer of heat from two spaces that have low temperature delta (temperature differential between the two spaces)…so if the surface separating the two spaces doesn’t receive sunshine…radiant barriers are not effective enough to use.
