Clear, no green

The newest edition to PPG’s collection of performance tinted glasses, Optigray glass is an ultra-neutral, warm-light-grey glass designed to maximize light transmittance and clarity. By eliminating the green colour typically found in conventional clear glass formulations, Optigray glass produces a warm, ultra-neutral esthetic that brings crispness to vision glazing. To optimize performance, Optigray glass is designed to function as a substrate for solar control, low-e coatings such as those on Solarban 60, Solarban 70XL, Solarban 67 and Solarban R100 glasses. In a standard one-inch insulating glass unit, Solarban 60 Optigray glass has visible light transmittance of 50 per cent and a solar heat gain co-efficient of 0.30, which yields a light-to-solar-gain ratio of 1.67. With Solarban 70XL glass in the same configuration, Optigray glass generates an LSG ratio of 1.99 based on VLT of 47 per cent and a SHGC of 0.24. Optigray glass features an appearance that is significantly lighter and more subtle than Solargray and Graylite II glass by PPG. Optigray glass is certified at the silver level by the Cradle to Cradle Certified program.


Good enough for government

Toronto City Hall consists of two curved towers overlooking a saucer-like chamber below. The east tower, which stands at 326 feet, and the west tower, standing at 260 feet, have both been re-glazed with an IGU combination of six mm Pilkington Eclipse Advantage Grey/air/six mm Pilkington Optifloat Clear. These energy-efficient choices combine low-emissivity with solar control for energy cost reductions compared to ordinary glass. They offer design flexibility through the ability to achieve natural colour with subtle reflectivity, high visible light transmittance and interior glare control. The products are durable and can be handled, cut, laminated, toughened, heat-strengthened, bent and made into IGUs using standard processing techniques. Advantage Grey and Optifloat Clear are available in a range of colours and are heat-treatable with colour stability.



Beautifully reflective

Energy Select R42 is designed as beautifully reflective soft-coated low-emissivity glass suitable for high-rise residential and architectural facades. It provides moderate solar control and high levels of visible light transmittance. With its low solar heat gain co-efficient of 0.42 and high reflectivity, AGC’s Energy Select R42 is an outstanding choice for solar control.


Glittering interiors

Bendheim has partnered with Bart Halpern to introduce a new exclusive collection of decorative architectural glass to the interior design market. Subtle at a distance, the Bendheim Hospitality Collection’s combination of natural colours and metallic hues is dazzling and bold up-close. The collection features five Glitterati textile colours – champagne, gold, copper, silver, and black – laminated in Bendheim low-iron glass. Additional Glitterati options are available on request. Installed in partitions, doors and windows, The glass can be supplied fully fabricated to specification in sizes up to 60 by 120 inches and approximate thicknesses ranging 5/16 inch to ¾ inch. Greater sizes are available on special order.


Cool grey

Solarban Z75 glass is a solar control, low-e glass that features a cool-grey tint and offers architects and building owners an attractive combination of visible light transmittance, solar control and glare control. Because of its low exterior reflectance and neutral, cool-grey aesthetic, Solarban Z75 glass harmonizes well with other building materials and low-e glasses such as Solarban Z50, Solarban 67 and Solarban R100 glasses by PPG. Interior reflectance values of less than 10 per cent allow Solarban Z75 glass to provide building occupants with clear, natural outdoor views.  In a standard one-inch insulating glass unit, Solarban Z75 glass has visible light transmittance of 48 per cent and a solar heat gain co-efficient of 0.24, resulting in an exceptional light-to-solar-gain ratio of 2.00.


Alternative to soda lime

Launched in 2012 in Japan, AGC has started international marketing of Leoflex at Glasstec in October 2014. Leoflex is a very thin, chemically strengthened aluminosilicate glass, offering flexibility, weather ability and superior clarity as well as higher strength, impact resistance and scratch resistance compared to tempered soda lime. This results in new opportunities for manufacturers, product designers and architects to create lighter products with thinner, curved designs, while maintaining the beauty and durability of glass.  The lightweight Leoflex allows the architect and designer to save weight and energy through this revolutionary green solution. With this new product, AGC aims at opening new markets for glass in the industrial and architectural fields, by replacing either soda lime, polycarbonate or plastic solutions. Whether it is to reduce the weight of your solar module cover glass or to get clearer and lighter curtain wall modules, Leoflex offers groundbreaking opportunities. Leoflex offers various processing options (e.g. cutting, lamination, printing, painting, cold bending) and is available in thicknesses ranging from 0.55 to two mm.
