Foil is used in space-faring craft because of these great properties preventing radiant heat loss. Because space is a vacuum, there is very little heat lost by conduction, so foil is absolutely perfect.
Herein, do you need Vapour barrier with foil backed insulation?
Products such as vapour-check, foil backed or insulated plasterboard tend to act as a vapour barrier but with none of the joints or penetrations sealed. These products may cause moisture to accumulate and should not be used instead of a VCL or where a VCL is used.
Also know, does foil faced insulation work?
RadiantGUARD® foil faced insulation is completely different. This barrier actually reflects radiant energy that can translate into heat, thereby reducing gain in the summer and loss in the winter. In fact, foil bubble insulation can reflect upwards of 95-97% of the radiant heat that strikes it making it very effective.

Why is tin foil a bad insulator?
Conduction. … Aluminium foil is a great conductor of heat, which means it is a poor insulator when it is in direct contact with something hot. It is also so thin that heat can pass through it super easily when it has direct contact. This is they type of heat transfer that aluminium is NOT good at stopping.
Why should we not use Aluminium foil?
Leaching levels climb even more when spice is added to food that’s cooked in aluminium foil. Anything acidic sparks a particularly aggressive process that dissolves layers of aluminium into food. This research suggests that aluminium foil should not be used for cooking.
