i am *considering* sheeps wool insulation for a coffee shop refurb. i'm less interested in its thermal properties but more interested in acoustic performance. i need 100mm batts for a false ceiling between floors (35 sqm) and partition walls (10sq m).
has anyone got any experience of its effectiveness in this kind of application?
... also would its moisture retention properties help improve the climate in the building?

at a good deal more than twice the price of say acoustic rockwool i'm struggling to justify the expense.

are there any other environmentally friendly alternatives i may not have considered?]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=137&Focus=1519#Comment_1519 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=137&Focus=1519#Comment_1519 Mon, 26 Mar 2007 19:50:36 +0100 Mike George
Density is closely linked to accoustic performance [for airbourne sound] that is why mineral wool, particularly the 'high' density accoustic slab is better than less dense insulations. High density accoustic plasterboards are an alternative as the best way to insulate against airbourne sound is by using mass, not insulation. Are you considering fire resistance as well?

I see no advantage in retaining moisture in insulation of any kind, in fact you should have a vapour barrier stopping moisture from getting in to the insulation from your coffee shop.]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=137&Focus=1524#Comment_1524 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=137&Focus=1524#Comment_1524 Mon, 26 Mar 2007 21:02:28 +0100 biffvernon http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=137&Focus=1526#Comment_1526 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=137&Focus=1526#Comment_1526 Mon, 26 Mar 2007 21:12:03 +0100 nigel
The latter is far more suitable as an acoustic barrier. You don't say if you are concerned about airborne sound or impact sound as the solutions are very different.

My guess is its airborne in which case 100mm will be fine make sure there is an air gap as well.
Also make sure that its fitted tightly and there are absolutely no air gaps for sound to travel around as this will undermine any benefit of the insulation.

As an alternative warmcell can be used an acoustic insulant and there are other cellulose based products such as homotherm which have a high density.]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=137&Focus=1527#Comment_1527 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=137&Focus=1527#Comment_1527 Mon, 26 Mar 2007 21:31:56 +0100 Mike George http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=137&Focus=1529#Comment_1529 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=137&Focus=1529#Comment_1529 Mon, 26 Mar 2007 22:25:15 +0100 biffvernon http://www.secondnatureuk.com/info.htm]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=137&Focus=1530#Comment_1530 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=137&Focus=1530#Comment_1530 Mon, 26 Mar 2007 22:27:13 +0100 Mike George I also came across this, but have not read it yet , I can get it free in work!
