The topic of multifoils seems to come up quite regularly. The makers and suppliers seem to make great claims (perhaps matching the great prices) while others are sceptical and point to the lack of good evidence for their effectiveness.
I thought I'd try a little experiment to get a handle on the issue and have posted the results here:
I'd be interested to hear in what ways this test is rubbish, how it can be improved upon and whether anyone is willing and in a position, perhaps with more resources than a kitchen, to run some better tests.

Nice one Biff-very interesting stuff. How about trying this with the water temperature starting at around 40 degrees, thus creating an initial temperature difference of around 15 degrees.

Ok if you have an automatic data logger but seriously boring doing it the old fashioned way :)

Hi Biff, Mike and others. Have you spotted the discussion by John Garbutt on this subject in the latest magazine. It is entitled 'Look gift horses in the mouth'.

Well done Biff for having a go at an experiment.

Yes Keith, I read John Garbutt's article. Am I right in thinking that he works for Kingspan, a company that does not make multifoil insulation but whose market for other insulation products could potentially be damaged by increased market share going to those rival companies that maunfacture multifoils?
I amazes me that we have to have such a discussion. Surely we should know what works best by now, after all it's only rocket science.
