CHAPTER XIII.
COMPLETE SPECIFICATIONS FOR THE ERECTION
OF CORKBOARD.
102.—Scope and Purpose of Specifications.—These specifi-
cations and illustrations are intended to show corkboard insu-
lation adapted to practically every type of construction to be
found in old buildings or to be employed in new structures,
which specifications long experience has demonstrated to be
practical. In many instances, however, more than one specifi-
cation is given for the erection of corkboard to a given sur-
face, and no recommendation is made as to preference ; be-
cause the use of each and every one of these specifications is
a matter of selection based on experience and a knowledge of
all the conditions of the case, as previously elaborated.
The thickness of corkboard to use must be suited to the
temperatures to be maintained, and to a less degree to several
other factors that will vary in each case, all as noted in
Chapter XII.
