These days I have been thinking about some things concerning the
construction of strawbale walls.
I also had a look at the construction of walls with the rammed earth
Traditional, breathable strawbale wall : loam / strawbale / loam
disadvantages of this "sandwich" construction :
walls are difficult to finish straight, the same problem for the corners.
setting up of a strawbale wall goes fast and easy, but loaming is a lot of
a loadbearing wall can shrink over time, and loam will crack.
advantages of a rammed earth wall :
construction is easy and goes fast (?)
cheap (in materials, but it requires more loam)
straight and beautiful result
good loadbearing capacities
disadvantages of this type of wall :
poor isolation (for cold climates)
I was wondering if somebody has some experience in making a combination of
rammed earth / strawbale / rammed earth
If yes ....
Would the isolation properties be the same for this kind of construction
compared to a classical strawbale wall ?
What about the fire resistant ? Is it advisable to put the bales in
between without loamfinish ? In Austria they finished a strawbale wall
completely with wood, but they dipped it in loam before construction.
Would this also be a requierement if the straw is set up between 2 layers
of rammed earth ?
Which advantages/disadvantages do you see for this type of construction ?
What about he foundation ?
I am also wondering if the time required to loam a strawbale wall would be
+- equal to the construction of a rammed earth wall ?
Are there other techniques to isolate a rammed earth wall ? (Not with
foam, rockwool, etc ...)
Thanks for your help.
