IGMA Summer Meeting Opens on the Beach
Glass Manufacturers Alliance (IGMA) summer meeting opened today
at the Hyatt Regency in Huntington Beach, Calif.
The meeting opened this morning with the glazing guidelines working
group. The group continued a discussion begun at the last meeting
on creating guidelines for closing capillary tubes in the field.
The group had been asked to create a standardized method for guidance
for closing capillary tubes for the benefit of those end users who
prefer to close the tubes.
Since the last meeting, Bill Lingnell of Lingnell Consulting Services
had been able to test capillary tubes donated by manufacturers.
He reported to the group that he has used wire cutters and crimpers
to close the hard stainless and soft stainless tubes, and has also
tried putting a dollop of silicone on the end of the tubes, a method
that seems to work well. Lingnell said that he has gotten erratic
results thus far, and still has other methodologies to review, but
is closer to reaching a conclusion that will allow him to prepare
a technical bulletin on the subject for IGMA.
The gas permeability work group also met this morning. After the
group reviewed a near-final draft of the executive summary of phase
one of its evaluation of the permeability of sheet report review,
discussion moved onto the draft request for proposal of phase two
of the project. Phase two will evaluate the gas permeability of
edge seal assemblies.
One member of the audience questioned the benefit of just measuring
the permeability of a section of the edge of the insulating glass
unit rather than the finished system. Group chair Bruce Virnelson
of PRC DeSoto explained that data already exists on the permeability
of finished units, and since there is a great deal of variability
in that data, testing edge sections may provide some answers about
why the variability exists.
Following some final changes, the group aims to send out the request
to laboratories before the next meeting.
The IGMA summer meeting continues through Wednesday, June 13.
