Pilkington Optiwhite™ extra clear glass, which is produced in our plants in Italy, Germany, UK and the USA, is the most coveted product in the glass industry today. Why? Because it exceeds the ordinary concept of glass transparency and out-performs its traditional alternatives.

Pilkington Optiwhite™ and clear float comparison

Unlike others in its field, Pilkington Optiwhite™ provides excellent neutrality in transmission along with a superb colour rendering that allows a true and natural representation of the colours of objects displayed behind it. 

Thanks to its high levels of light transmission and almost no green cast that is inherent in standard float glass offerings, Pilkington Optiwhite™ is perfect for applications with exposed edges, particularly when thicker sheets are specified, which in standard alternatives would demonstrate a greenish tint due to the iron oxides contained in their raw materials.

By comparison, Pilkington Optiwhite™ extra clear glass is obtained from a rigorous selection of raw materials, high grade sand with a reduced iron oxide content, and a thorough and careful control of the various parameters during the melting process – ultimately providing the market with an outstanding product.

Thanks to the resulting incomparable colour neutrality, Pilkington Optiwhite™ is the ideal product for showcases that contain paintings, valuable objects and works of art, as well as for interior design solutions, where it can be successfully used for stairs, furniture, balustrades and partitions.

By allowing maximum light transmission, Pilkington Optiwhite™ is perfect for windows in buildings that receive limited amounts of light from the outside, providing greatly enhanced natural light and the additional benefit of reducing electricity consumption.

By providing Pilkington Optiwhite™ in thicknesses from 2 mm to 19 mm, NSG Group offers architects and designers the widest range of extra clear glass in the market. 

The glass can also be used as a substrate for a number of other functional glass products providing thermal insulation (Pilkington K Glass™ OW or Pilkington Optitherm™ S3 OW), solar control and low-e properties (Pilkington Suncool™ OW range), noise control (Pilkington Optiphon™ OW), safety and security (Pilkington Optilam™ OW), fire protection (Pilkington Pyrostop®), anti-reflective properties (Pilkington OptiView™ OW), anti-corrosion properties for bathrooms (Pilkington OptiShower™ OW), decoration (Pilkington DesignPrint, Pilkington Screen Printed Glass, Pilkington Enamelled Glass) and more.

It can be used as single glazing or as a part of insulating glass units. It can be easily processed, toughened, laminated and bent. It is available in standard sizes, but NSG Group can also supply Super Jumbo glass plates of up to 20 m in length. These oversize glass plates offer the largest architectural glazing dimensions currently available on the European market. In addition, and upon request, a width of more than 3.21 m can be considered for supply.

By supplying Super Jumbo extra clear glass plates, NSG Group helps architects and engineers to realise their customers’ concepts such as the K11 Art & Cultural Centre in Hong Kong or the Urìa Menéndez Headquarters in Madrid.

The glass has been successfully used for many great projects worldwide including the amazing glass platform, Le Pas dans le vide in Chamonix, the beautiful Antinori Winery in Bargino and the outstanding La Terrazza in Milan.
