Seismic Protective Laminate for Buildings, Windows and Glass
Seismic events, by their very nature, are unpredictable in strength, duration and effect. Efforts to strengthen buildings to cope with the effects of an earthquake often overlook the vulnerability of the glass elements that make up the building.
Some modern glazing systems allow for a degree of drift, which means that there is some flexibility within the window frame prior to the glass becoming the subject of the seismic forces acting on the building as a whole. However, this is not an exact science and it has been demonstrated, on many occasions, that windows subjected to such forces often shatter, sometimes causing catastrophic injuries and/or death.
