STRENGTH Under wind pressure, tempered glass is approximately four times as strong as annealed glass. It resists breakage by small missiles traveling approximately twice as fast as missiles which break annealed glass. Tempered glass is also able to resist temperature differences (200 ° F - 300 ° F) which would cause annealed glass to crack. Annealed Glass Tempered Glass Typical Breaking Stress (large light 60 sec. load) 6,000 psi 24,000 psi Typical Impact Velocity Causing Fracture (1/4" light 5 gm missile, impact normal to surface 30 ft/sec 60 ft/sec............. SAFETY............ Fully tempered glass is used in many applications because of its safety characteristics. Safety comes from strength and from a unique fracture pattern. Strength, which effectively resists wind pressure and impact, provides safety in many applications. When fully tempered glass breaks the glass fractures into small, relatively harmless fragments. This phenomenon called "dicing," markedly reduces the likelihood of injury to people as there are no jagged edges or sharp shards............... ...............Fully tempered glass is a safety glazing material when manufactured to meet the requirements of the ANSI Z97.1 Standard and Federal Standard CPSC 16 CFR 1201. Federal Standard CPSC 16 CFR 1201, as well as state and local codes, require safety glazing material where the glazing might reasonably be exposed to human impact. This includes doors, tub and shower enclosures, side lights, and certain windows. Applicable building codes should be checked for specific information and requirements............. Versatility and Adaptability Glass fencing's greatest aspect is its versatility. The most obvious benefit of having a glass paneled fence or balcony is that it does not obstruct your view, and they are often utilized to take advantage of panoramic views of nature or cityscapes. Glass fences also block the sound and wind. For this reason, they are often referred to as glass sound walls, and are often seen alongside noisy traffic corridors. But there are more advantages. Glass fencing is used for upgrading. Many homeowners are troubled by weathered, deteriorating wrought iron and wood fencing. Not only must this type of fence be periodically primed and painted, but it does little to block out sound or wind. Akme Glass Company will tear down your old wrought iron or wood fence and haul it away for you. They will construct a new glass fence, which is virtually maintenance-free, in its place. Glass fencing is adaptable and utilized to accommodate different types of terrain as well as sloped, stepped, and curved walls. It can be secured to decks, patios, and balconies in several different ways. It can also be retrofitted to existing block walls in order to extend noise attenuation without impeding sight lines. A gate is another option for your glass fencing or deck. Gates come with a lockable latch system and stainless steel hinges.
