Tin-foil to reflect heat?greenspun.com : LUSENET : TimeBomb 2000 (Y2000) : One Thread
I read someplace that "space-blankets" (emergency blankets) can be used in a room/tent to reflect heat back into the room so it is not absorbed/dissipated by the walls.
Can tin-foil be used as well? A roll of tin-foil would go a long way, but since it is metal, I wonder if the metal's conductivity of heat/cold would make it less (not?) useful than the plastic "space-blankets".

1) Space blankets are not prohibitively expensive.
2) You will have MANY better uses for the foil(like food prep. and preservation), as you will NOT have enough regardless of your vision for the duration of the dislocations. cr

Look at your local Home Depot, Lowes, or lumberyard for "reflective foil" attic insulation. Don't bother with kitchen Al foil - that would be a waste of money.
Start with your attic - if you don't have R30 already in it - then caulk and weatherstrip the doors and windows, then check your walls. Tin foil inside will be less effective than any of these.

Saw an interesting use for a tin foil-like material used to melt snow into drinking water, on Dateline last night.
Use as a solar reflector to heat snow, have it at an angle to collect melted water into container for drinking.
