the ceiling construction, as floor <strong>insulation</strong>, and the <strong>insulation</strong>
of the walls can be made continuous, without breaks at floor
(ceiling) levels, by providing an interior building structure of
concrete and steel to carry the load of the cold storage section
of the building and its contents, and casing it in with self-
sustaining curtain walls, of brick or concrete, entirely independent
of the interior structure except for a few small metal
tic'^. The <strong>insulation</strong> of outside building walls is then applied
against the inner surface of the curtain walls in a continuous
sheet, without breaks at floor lines and connecting with the

proper floor (ceiling) <strong>insulation</strong> Mdierever it may occur; but
where insulated interior dividing walls are required, such as
those walls that may divide the cold storage section of the
building from the dry storage section, provision frequently
need be made only for self-sustaining cork walls unsupported
•by interior building walls of any kind. In this way the cold
storage section of the building is literally enveloped wdth insu-
lation, loss of refrigeration is reduced to a minimum, and all
ceiling <strong>insulation</strong> disappears in favor of floor or roof <strong>insulation</strong>
next abo\'e.
In old buildings of mill construction, it is frequently possible,
and if so, highly desirable, to remove the ceiling and
floor coverings at all wall lines where <strong>insulation</strong> will occur,
and make such <strong>insulation</strong> continuous through and between the
