Hello Steve,
Thanks for the post. Wool insulation is both widely
used and available here in South Eastern Australia, with at least 4 companies
marketing it as a product in my town alone (of 80000 people). Australia being
the world's biggest sheep/wool growing nation may have something to do with it!!
Similar to the US wool prices have been low for years with global prices largely
linked to the enormous stock pile of bale stored in Sydney. (they were
threatening to burn it at one stage - now it looks like the Chinese have bought
the lot much to the joy of the Aussie wool grower. Funny sheep prices are
fantastic at the moment...)
The insulation in my ceiling is just loose fill
100% scoured wool - and applied with a blower-type device. It cost AUD$730
for 14 squares, which is as cheap as you'll get...The R rating is between
R2.2-R3.5. It is treated with a borax-based compound (Sodium Octoborate
Tetrahydrate) to negate the impact of wool moth. Our roof is tiled and well
ventilated, although high humidity levels only occasionally arise in summer
when rain is about - usually the extremely low summer humidity and 40-45+
degrees centigrade temperatures are the order of the day - something the wool
will help to reduce the desiccating effects of - we hope!! Nonetheless the
occasional humidity is nothing like what you would have to put up with. Another
product that we are getting is a composite wool/poly batt - it is 60:40
Wool:Poly. This will be used in the stud walls and ceiling of the sunrooms we
are building. The batts are R3.5. Flammability of all wool products is very
low too.
We also have pure woollen pillows, underblankets
and doonas which you have to experience to believe. These too were pretty cost
effective and after one night you'll never go back.
I figure for all the damage sheep have done to our
landscape we should be utilising their products in as sensible a way as possible
- not bad eating either.
Go for it.
Cheers,
Yours and Growing,
Darren Doherty
