Update on multifoil insulation.

[Johneds]

September 2006 edition of NHBC technical newsletter has a small piece on multifoils. It says:

(after a brief intro on what multifoils are etc., which I think I can skip)

'We are aware that there is a debate between various manufacturers and testing organisations over the performance of these materials. It is suggested that their performance is far below the manufacturers' claims.' [I know, we knew that] 'So where does NHBC sit in this debate? Whether or not these materials do have such a good thermal performance is something that will emerge over the next few weeks and months when a consensus is reached on how the performance should be measured.'

It then briefly says that NHBC will not accept them until the situation becomes clearer.

It seems to imply that the great multifoil debate may be coming to conclusion. I would be interested to know if anybody has any other info on this.

AAAAAAAAGGGGGGGHHHHHHHHH!!!!!

For that totally unwarranted calling out in class you must write an essay on the relative merits of kingspan vs multifoils

Or perhaps just a brief synopsis of the Green Building Forum thread would do.

'Spose a couple of catridges of expanding chemical foam are out of the question as a substitute then? :wink:

Nooo... I have rollercoasters to SAVE! Is that a good enough excuse?

PS a good vest is the answer.

SAVE THE CYCLONE!!!

 

[Gervase]

Ah, but do you line your vest with Bacofoil or goose-down?

 

[Nemesis]

Brown paper and goose grease! Sewn in. What else?

Bacofoil? Oh the Welsh... kinky.

Ach, you're just jealous!

 

[Nemesis]

And have you signed our petition yet?

No

So bloody do it now.

I thought you preferred to take your thermal protection internally, in liquid form.

I confess that I'm very puzzled by the controversy over multi-foil insulation materials. Surely scientifically testing the thermal insulation properties of a material is pretty straightforward, and would give a definitive answer as to whether the stuff does what it's supposed to do?

Isn't that what the Agrement Board is for?

How can there be so much uncertainty?
