RE: Sealing Creosote?
Here in the northeast of the USA, good practice is to put a barrier
membrane towards the INSIDE of the house to prevent condensation
problems. I suppose someplace where there's more AC than heating, it
might make sense to put the barrier on the other side. Tyvek is for the
outside and is meant to breath, also to avoid condensastion problems.

Probably these issues are worth thinking about on bigger boats. Barrier

Seems that the biggest threat from creosote is in the dust when
sawing or direct contact with the stuff, as well as when it gets
into the water supply. The actual treated timbers, especially older
ones are really not a significant threat. The two layers or poly is
probably the best solution and I will see what the floor has under
it as well.
You folks have made my frined very pleased:-)

A friend
It was built in 1952 by my father. The health concerns and the smell
are two different issues. Visitors can smell a faint odor of
creosote in my house. When I go away on vacation and come back, I
can smell it for the first few minutes when I enter the house.
The health concerns are from direct skin contact. If the interior
surface is covered you should not have a health problem. Exterior
walls can be exposed. Paint will seal it. A vapor barrier would also
work well. The web has a good bit about creosote construction,
especially UK sites if I remember. There have been long term tests
done that show no migration of the creosote from the wood used in a
house.
The laws about its use vary from country to country. In the US,
creosote is now a restricted use pesticide. It may affect resale
values. Restricted use pesticides are used in houses on an ongoing
basis by professional exterminators.
I can tell you that creosote is very very weak as a pesticide. It
does not kill any bugs but it does discourage termites and rot.
Creosote is coal tar and has been used in boats.
If you do not care for the smell, seal it off and enjoy a house that
will last a very long time.

Tyvek and the like "breathe" and would not be suitable, what about two
layers of 6 mil poly?

Nels,
Seems like a barrier membrane would do the trick, but..... that might well
raise other issues of dampness, mold and rot behind the membrane. Has she
consulted local wisdom regarding what other owners of similar fortresses
have done?
I envy your visit, take LOTS of pictures!

Hi Bolgeristas,
I have a question that is a bit off-topic, but the reputation of
this group is so great that it goes beyond Bolger boats! A friend
here in Norway purchased a cabin that had been constructed from
creosote empregnated ties, which has now been declared dangerous to
one's health - even though the ties are covered on both the inner
and outer walls. She wants to tear out the inner wall paneling and
seal the surface of the ties to prevent possible fumes from seeping
inside. Could Tyvek do the trick? Or some other sealer? She would be
forever indebtd to us if we could find a solution. Otherwise she
cannot live in it and must have it torn down and disposed of at
great expense. It is buildt like a fortress and cemented into solid
rock!
Visiting Norway is like living in a Woodenboat magazine every day.
Anyone who has been here will know. From tiny prams to larger multi-

And there has been about ten drops of rain since I arrived two weeks

Nels,
If you know what the actual carcinigen in the cresote is you could
figure out what the molecule's shape and size is and wether or not
it could penitrate the tyvek's pores.....check dupont's website.
How about just a VBL of some sort to isolate the stuff......that may
require some type of aditional ventiation or air circulation to keep
moister under control. Maybe a radon type evacuation system could be
used to pull the air/or nasty's out. I would think there has to be
info on the web for this kind of thing, maybe EPA or HUD has
something. They may even recomend to treat it like
abestoes......cover it and let it be.
Good luck,
Jason
Hope your taken some boat pictures for us
