Thank you all for the kind comments. I was on no way bothered by the "lack of gratitude"... only by Mom's seeming to have no understanding of the situation...

The kids themselves were most appreciative...

It is a nice feeling knowing I was in the right place at the right time~

First off, cling film or polyethylene will do no better than a space blanket at repelling the wind - they are all non-permeable films that would block the wind equally well. What the space blanket will do that the other 2 materials won't, is to help reflect radiant heat waves back toward the source of that radiant heat (the body). If a person is losing body heat, one of the primary modes of the heat loss will be through radiation, and any means that can reduce that radiant heat loss will be benecial.

Given that the girls were wet, conductive & convective heat loss would have still be the main modes of heat loss, and, yes, a space blanket does not do anything to reduce conductive heat loss (has no insulation value). Nonetheless, using a space blanket would not worsen this mode of heat loss in this situation.

I think what Petes getting at is if the person is already cold all a space blanket does is keep them cold.
A survival bag is better suited.

Or a space blanket inside a survival bag.

Cold doesn't reflect

Neither was I,.. it should be said .. Just surprised by the lack of it, since that implies a degree of nonchalance on the part of the guardian, but that experience would never stop me doing the same again if needs be, I just found it a surprising observation.

I carry thermal protection aid's, these are mca approved for this situation coast around 10 , I used this on a hypothermic swimmer, and when the ambulance arrived they made comment that we had the warmist hypothermic person they had seen. That was after they cut the suit to get access!

We now have a few of these in club house now for emergency's. The one I used was from my boat.

Great thing these they have legs, hoods and Velcro entry.

Regards

How hard was it to make the hot pasty cabinet fit the console?
