Dear Harald - and all of
you.
Yesterday a symposium on renewable
building resources at the straw-bale congres hall took place. You did not miss
much, as there was not much visable power for break throughs and there
where 20 minutes time to reflect on straw for professional applications. Along
the last idea during the Dutch gathering in Middleharnis to proceed the Dutch
network within a VIBA working groep, VIBA will invite for a meeting during the
last quarter of this year.
A manufacturer of wool insulation informed
on the properties of their product (for application similar to
rock-wool):
firetest: B@ / DIN
4102
moisture: capability of absorbing 33%
water
thermal: just saying 2 times better than
traditional isolation material
They don't use borax, just
salts.
price: higher than
rockwool
address: www.Doscha.nl
Together with Raab Kaercher they developed
"ceiling"-plate based on woo "Kairatin"l: which intends to absorb aldehydes in
sick buildings.... (better build wiht
straw)
Interesting is their test that reduces 300
ppm formaldehyde (deadly) back to 0,05 ppm within 24
hours.
I guess this is an inherent property of
wool, nicely offered in their product. More information: www.Kairatin.nl
All the best,
Martin
