steel members of the framed
structure are being joined with
nuts and bolts, drywall using
LGSS and cement fiber boards in
the external and gypsum boards
in the internal wall faces, and
rock wool for insulation which
has led to water saving since
plaster and curing is not
required. The prefabricated
building components are being
sourced from factories in Indore,
Bawal, and Palwal.
