SAVING WEIGHT: A DESIGN EXERCISE IN GLASS

Triplex Safety Glass, Birmingham, England has announced a new "super laminated" windshield which offers weight savings, design flexibility and improved safety. Ogle Design, Letchworth, was commissioned to produce a design exercise exhibiting production possibilities of Triplex 10-20 glass. Ogle took a standard Princess 2200 and modified it into what is known as the 10-20 Glassback. Triplex 10-20 is thin, toughened glass of good optical quality. The sunroof panel of the Glassback is only 0.09-in. (2.3mm) thick, the rear roof panel and side door windows are 0.12-in. (3mm), the rear quarterlights are 0.15-in. (4mm) and the tailgate is 0.20-in. (5mm). A 0.03-in, (0.76mm) sheet of tough, pliable poly-vinyl-butyral is placed between the inner and outer glass and vacuum is applied to remove any air trapped inside. This sandwich is then transformed into an autoclave, a large cylindrical pressure cooker over 36-ft (11m) long. The automaticaly controlled autoclave then bonds the toughened glass, vinyl interlayer and annealed outer glass into a 10-20 windshield. Ten-twenty has been given full approval under international safety standards in Germany, France, Italy, the US and the United Kingdom.
