Does silver foil reflect heat as well as light?
Yes
Why does putting foil behind radiotors reduce heat transfer?
The foil reflects the heat back to the radiator thus reducing convection off of the radiator.
How does silver coating on surfaces of glass walls minimise heat transfer?
being a poor radiator,the two silver faces reflects heat back and forth and reduce heat by radiation.
Which will conduct more heat foil in the sunlight or a sidewalk in the sunlight?
foil
Is aluminum foil a heat absorber?
No, it really reflects heat.
Why thick silver foil and foam plastic are often placed between the ceiling and the roof of the house?
It is a barrier to radiant heat.
What conducts heat better mirrors or foil?
A metallic foil (from gold, silver, copper).
Does silver foil reflect heat as well as light?
Yes
Why does putting foil behind radiotors reduce heat transfer?

Can you cook with silver foil in liquid?
yes you can . silver foil gives off heat so putting water in it would just make the water hotter.
Do you cover a dutch apple pie with foil?
No, but you do reduce the heat in your oven partway through cooking.

Will tin foil help for cooling down houses?
If you wanted to cover the roof, or entire house with tin foil then that would reduce solar heat gain by reflecting the solar radiation away. Seems a bit extreme though, and hard on the eyes of passers by.
Why not cook potato in black dull foil?
Black foil would attract heat and burn the potato if you put it in on a too high heat, or left it in too long, it would be very unpredictable but silver foil reflects heat, and cooks it slower and is easier to tell when you have to take it out : it's just easier!
How does reflectivity of the aluminium foil influence to keep the food warm?
Heat can be transferred by 3 mechanisms: conduction, convection, and radiation. When food is covered by aluminum foil, the foil does reduce convection a bit because the air next to the food is trapped there. A bigger effect is the reflection of the heat by the foil. Rather than continuing on its path to dissipate into the surroundings, the heat is reflected by the foil back into the food, thus helping to keep it warm.
If a house has plastic vapor barrier on the inside walls and a foil barrier on the exterior of the house should you remove the existing old outer foil when residing?
Unless your home is heated by electric baseboard you may take it down if you wish. However the foil has reflective heat values, which means it reflects out the heat from the sun in the summer and reflects in the heat in the winter.
Why is the inside of a thermos flask silver?
To reduce heat loss by thermal radiation.
