I have just received some estimates for a job in Ireland and the prices seem very comparable. The Warmcel installer wants €16 (£11.22) per m2 (including VAT and installation) to do the walls (145mm thickness).

I can buy sheep's wool from here:

http://www.sheepwoolinsulation.ie/products.asp?cat=11

for €17.50 (£12.28) per square metre at the same thickness. This price is even better than it seems as the warmcel price is total m2 and includes the area covered by the timber studs. The sheep's wool excludes the timber area. As I can install the insulation myself the sheep's wool works out about the same price in the end.

Am I missing something here? Is cellulose much cheaper in the UK? Has the sheep's wool got much cheaper?

Which would you use? I know that cellulose can potentially fill even the tiniest voids - but I worry about slumping and mould.

Comments appreciated

Diy would be the better way to go.

What are the rules about selling/buyng fleeces these days? I think the Wool Marketing Board price is about 70p per kilo.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=852&Focus=9256#Comment_9256 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=852&Focus=9256#Comment_9256 Sun, 11 Nov 2007 22:27:39 +0000 richy
He compares shearing to weeding; non profitable but essential.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=852&Focus=9367#Comment_9367 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=852&Focus=9367#Comment_9367 Wed, 14 Nov 2007 09:33:10 +0000 ted
70p/kg is the average of what the WMB sell for, the difference being their 'not-for-profit' running costs.

In the UK (excepting the Shetlands) farmers are not allowed to sell fleece to anyone other than the WMB.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=852&Focus=9385#Comment_9385 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=852&Focus=9385#Comment_9385 Wed, 14 Nov 2007 12:58:37 +0000 biffvernon
Clearly we need to buy the black wool. It will absorb heat better ]]>
