air or any sort of gas is not that good in conducting heat in relation to other materials.
since foam consists of many bubbles with trapped gas it both stops convection by simply being in position, and prevents conduction of heat through it, due to the gas inside.

Almost nothing but time will remove this stuff. If you have a pumice stone you may be able to hasten the process along but mostly it is a matter of picking the foam off a smidgen at a time.

Hi. It slows down the heat transfer because radiation or warm air takes a while to go from bubble to bubble inside the foam.

Air Pockets stop heat. Foam has lots of air pockets

Obviously, the sealant by itself provides no serious hindrance to fire, as its hydrocarbon bonds readily support combustion. However, when backed by inorganic insulation, such as rockwool or ceramic fibres, it can act as an effective seal to thwart smoke and hose-stream passage, particularly in inorganic joints. It is, however, advisable to avoid direct contact with metallic penetrants and through-penetrating cables, as the heat carried by the penetrants may jeopardise the sealant.

It depends on if you are talking about heat insulation or sound insulation. They are fairly similar, but have their differences.

It traps air...but it is also very flammable! So be careful where you use it. Safety first.
