The following constructions of laminated glass are most commonly specified in earthquake-prone regions. As with all laminated glazing, the glass can be supplied tinted or reflective for light and solar control purposes. The lites of glass can be either annealed or heat-strengthened. Oldcastle BuildingEnvelope does not recommend tempered glass be laminated for seismic applications because of "wet blanket" fallout concerns.
When insulating glass is required for thermal performance in earthquake-prone regions, Oldcastle BuildingEnvelope recommends that both lites of the IG unit be laminated to provide maximum glass retention both inside and outside the building envelope.
