Much as I hate to agree with anyone about anything, I'd have to agree with
WatJohn.
The modular panels certainly do not minimise the amount of materials used
nor do they do much of anything to make the lives of the builders any
easier.
The wood framing is not much more than excessive and not-very-Green
packaging to facilitate transport of the straw and creates a thermal
penalty to boot.
No sensible builder would make a wall in that fashion to accommodate
conventional insulation materials so it makes even less sense for a
builder who touts environmentally-responsible methods/materials to be
doing so.
But the ModCell system especially bothers me because we know that straw
can be precompressed into panels that are capable of loadbearing without
the need for the inclusion of "studs" or posts and when precompressed in
such fashion, the roof bearing assembly can be minimal so the full
wall-width wooden members of the ModCell system are not only thermal weak
links, they are structurally redundant as well.
