Insulation

I hope nobody has used this stuff for insulation!

That's not ideal :?

"She has since been advised by experts that, unless properly treated, sheep’s wool is considered ‘fillet steak’ for moths."
What a strange analogy, considering moths don't eat meat if it were fillet steak she wouldn't be having a problem :eusa-think:

There was a massive failure of the insect treatment in commercially available lamb's wool insulation a couple of years back, which resulted in the National Trust stripping it out of half a dozen buildings, and various other catastrophes around the country. The suppliers/ manufacturers closed the business overnight and opened up again the following day under a new name.

I won't have anything to do with the stuff.

From that supplier or wool full stop? I've wondered since the awful tragedy at Greenfell tower if more people would move to other insulation materials given Kingspan type panels seem to be pretty flammable even though we're advised to use them over polystyrene

I got some frozen food delivered with an insulation wrapping of wool inside perforated plastic. It suggests reusing it as loft or other insulation - I think not, it's going in the bin!

There is a fire resistant Celotex and Kingspan.

Both Celotex and Kingspan are over twice as efficient an insulator as wool. So if you need 6 inches of Celotex, you'll need more than a foot of wool. Wool isn't as good an insulator as mineral wool (fibreglass), which is now a 100% recycled product, much cheaper, and benign to handle (nothing like the old yellow and then pink stuff which was horrible). There seems to be a constant search for the next fashion in insulation, and there is certainly a case to be made for some of them, but until they can beat the price and performance of the standard everyday stuff stocked by every builder's merchant and DIY shop in the country, then I won't be using them, or specifying them.
