Insulating basement walls:
Last year in this group I ask about insulating basement walls. Learned
a lot about vapor barriers and types of insulation.
Last post:http://groups.google.com/group/alt.h...hread/thread/7...

One suggestion made in a reply was to not fill the stud bays all the
way to the floor with fiberglass. Stop about 24" from the floor. This
would prevent the fiberglass from filling/soaking up water if I ever
did have water flood the basement.

Has anyone ever done this ? And if not fiberglass, why not fill the
last 18"-24" with Styrofoam or polystyrene. Â*If so, which to use ?

Thanks

That would depend upon where your house is located. There are many types
of flooding. Flooding from a rising water table, floods from rising
rivers or streams, water leaks from broken foundation walls, internal
floods from broken pipes, or water heaters, among others. Where I am
located (on a hilltop) only the last two applied. I have had water leaks
from the water heater, and a foundation crack which leaked during a
heavy and sustained rain, none of which did any more damage than soaking
the carpet in those areas. Neither were visually noticeable, but my feet
and ears discovered the water. I replaced the water heater and sealed
the crack.
My fiberglass insulation extends to the floor plate and only the wall
leak wet the insulation, and that was minimal.

Use rockwool in basements - with no vapour barrier. RockWool will not
cmopact when wet, will not support mold, and will not lose R value
after being wet.- Hide quoted text -

Never heard of it, I did a quick search on HomeDepote.com and didn't
find anything.
Where do you get it.
Here in Canada Home Depot carries it. Roxul is the brand name.
