I like a lot of combinations and think it
is good to use the right solution for the right person.
People survived by flexibility.
Panelling (wooden planches and vapour screen
is also OK) can be very handy. With the strikt building regulations from
Austria and Germany it may well be the only sollution.

Hi,
The response from Henk makes me think of another subject where I'd love to
learn more, and perhaps the knowledge on this list can help this?
I'm aware that:
-An alarming number of Hurricane Katrina survivors got severe health problems
(some died) from being relocated to emergency mobile homes made from fresh OSB.
Use 0 formaldehide
-In comparative research on particle board, plywood and OSB, the OSB
ranks as the highest for fungi susceptibility.
Use it In dry inside conditions
-Last year I read that 60% of OSB on the European market came from threatened
rain forest.
Is that the case for Stirling plates?
-I've been made aware that the production of OSB (and burning of wood chips)
has caused a 'vacuuming' of the forest floor, reducing the necessary amount of
carbon in forest eco-systems.
That the proces doesn’t leave left
overs doesn’t mean that the wood should come frome the forest Floor.
-As part of my University research in 2008, I made a price comparison
between using solid wooden boards compared to OSB and investment was equal (in
CZ), only the time of mounting it spoke in favour of OSB.
-OSB may act as a ticking bomb in case of poor detailing by the construction
company, allowing moisture to get to the OSB: they will rapidly turn black with
fungi spores, but without visual signs for the occupant.
All biological material does
-What does OSB do to the 'breath-ability' of the house?
No breath-abillity is OK for some people,
just ask and you will know.
-How far does your OSB travel? The 'baubiologie' approved brand from
Scotland may be great on the British Isles, but how appropriate is it on
mainland Europe?
There is no lime in the Netherlands.
-I'm convinced that (beyond the 4 good points mentioned yesterday by Derek and
?), there's a special 'marriage' happening between the integration of the earth
plaster and straw, which provides additional positive feed-back loops which our
isolated scientific science approach have not yet proven. In other words; this
is typically lost when useing OSB. (stays if the french dip is applied, but
bales has to be mighty dry before installing to avoid fungi in the OSB).
So, with that out in the open: Please "Teach me Tiger"....????
Cheers,
Max Vittrup Jensen
