The request by the Insulating Glass Manufacturers Alliance (IGMA) that ASTM
E 2190, Specification on Insulating Glass, be included as an additional reference
to the CGSB 12.8 standard under section 220.127.116.11 e will not be referenced in the
2005 National Building Code of Canada (NBCC) per the recommendation of the Provincial
and Territorial Policy Advisory Committee on Codes (PTPACC). It has been "deferred
due to deficiencies in the code process and [is] not due to the technical or economic
arguments that IGMA presented," stated an IGMA press release.
The ASTM standard reference, however, has been made a "number-one priority"
for the next code change cycle.
IGMA's executive director, Margaret Webb, and Ray Wakefield of Trulite Industries
had presented support for the code changes during the CCBFC meetings in Ottawa,
Ontario, June 12-13. According to the announcement, IGMA had been advised in mid-May
that the PTPACC would not be recommending the additional reference, but gave no
reason for the deferral to the next code cycle. Webb explained that the PTPACC
meetings are closed to the public and the minutes from the meetings are unavailable
to the public, which is why she and Wakefield returned to the CCBFC this month.
"While members of the CCBFC stated their support for the reference, attendees
at the meeting were advised that, as there is no provision in the current code
process to adopt interim changes, our request cannot go forward at this time,"
stated the IGMA announcement.
According to Webb, their next move will be to go to the individual provinces
and territories for adoption. She said they have already received a request from
the Ontario Building Code to provide technical equivalency information on the
ASTM E 2190 standard and to identify the differences between it and the CGSB 12.8
"Ontario has 40 percent of the construction industry in Canada and is
one of the few provinces with its own building code," said Webb.
IGMA said the CCBFC and PTPACC are currently reviewing the past code cycle
to establish procedures that will be more responsive to interim changes and standard
harmonization efforts in the future.
