ing's rigidity. When used in tall buildings, the glass block panels experience earthquake motions that cycle back and forth very slowly relative to the vibrational frequency of the glass block. Thus, the glass block's ride during an earthquake is a smooth ride. The building acts like the soft shock absorbers in cars which soften the passenger's ride from the irregular imperfections in the road surface. The second attribute of the glass block is the rigidity of the glass block panel relative to the rigidity of short buildings or residences. The rigidity of the glass block is such that the critical vibrational frequency of the glass block wall or panel is greater than the more severe vibrational frequency of the earthquake ground shaking. Therefore, the g-forces from the earthquake are not amplified or turned into the ground motion as are other architectural items such as chandeliers or bookshelves.
Glass block panel design criteria currently specified in the UBC provides an excellent architectural product that performed very well during the Northridge earthquake. The combination of creative architectural design and compliance with the recommended detailing (for example see Figure 4) and the UBC requirements produces an aesthetically pleasing and safe glass block panel system.

EDGE FLASHING
Dur-O-Barrier Wall Flashing Installs easily to masonry, concrete, steel, gypsum or wood. It's manufactured withinils (8mm) of rubberized asphalt and 8 mils (2mm) of high density cross laminated polyethylene film so it resists puncture, abrasion or other damage during installation and even heals itself if slightly damaged.
Dur-O-Barrier installs with greater ease than other wall flashing materials. Corners and dams are formed easily on the job.
Dur-O-Barrier Wall Flashing provides excellent moisture resistance, flexibility and good tensile strength for long term performance and works best with Dur-O-Wal Stainless Drip-Edge Flashing Strips to form a Complete System with a clean, straight appearance.
Available in roll widths of 12, 18, 24 or 36, Dur-O-Barrier is the fast, easy and economical way to install wall flashing.
