Canada: Grand Bibliothque's Glass Panels Defective, Experts Say

A year after decorative glass panels started to shatter and fall from Montreals Grande Bibliothque, experts say 30 per cent of the 6,200 panels were inadequately safety-treated prior to installation.

The panels were also susceptible to shattering, the experts found, if three conditions prevailed simultaneously: the panels were scratched or cracked, they were too tightly attached to the building, and they were forced to withstand extreme temperature changes following installation.The study, commissioned by the Bibliothque et Archives nationales du Qubec, was made public this week.Six of the panels fell from the exterior of the newly opened library at the corner of Berri St. and de Maisonneuve Blvd. last June and July. A seventh panel shattered early last month.

The 2.2-metre-long panels broke into rounded, pebble-sized pieces, and posed no danger to the public, library spokesperson Patrice Juneau said Thursday.

This is more annoying than worrisome, he said.
