1.i. Special Applications

Glass for Special Applications provides unique characteristics. Pilkington Mirropane is an on-line coated glass developed for use as a one-way mirror where total clear vision is required and specific lighting conditions can be achieved. Under specified lighting conditions it offers an effective means of providing undetected surveillance and high quality one-way vision to achieve complete privacy. Pilkington Mirropane is used in applications such as supermarkets, computer rooms, banks or cash offices, where areas need to be kept under observation or hidden from public scrutiny. It is also appropriate for patient monitoring in hospitals or residential care establishments.

Pilkington Optiwhite is an extra-clear, low-iron float glass with very high light transmission. It is practically colourless, and the green cast inherent to other glasses is not present. It is therefore ideal for use where glass edges are visible or where a neutral colour is desired. As it has got high light transmission it achieves greater brilliance and transparency, allowing a clear and true representation of colours when viewed through the glass. These same qualities also allow for maximum interior daylight. It is the product of choice for architects for buildings where transparency and brightness are of paramount importance. Pilkington Optiwhite can be combined with other products from the Pilkington range. For example, when combined with Pilkington Suncool it decreases the risk of thermal breakage and reduces the need for toughening, while providing high performance solar control and low-emissivity. When used in exterior glazing, it enhances true colours and allows for maximum light transmission, even in thicker laminated combinations. In domestic windows, Pilkington Optiwhite maximises passive solar gain to reduce the need for heating during cold sunny days.
Pilkington OptiView is an on-line coated anti-reflective glass that reduces interior and exterior light reflectance. Pilkington OptiView Protect combines two proprietary anti-reflective surfaces in a single laminated glass, reducing interior and exterior light reflectance to around 2%, and allowing more visible light to pass through compared to clear float glass. As a consequence, views from both inside and out are clear, un-obscured and virtually reflection-free. Pilkington OptiViewProtect offers all the traditional benefits of laminated glass, such as improved safety, enhanced security, durability and acoustic properties. Furthermore, it provides protection from UV radiation (UVA and UVB) by blocking over 99% of UV transmittance, helping to reduce fading of the contents and interiors of a building. Pilkington OptiView products are ideal for a wide range of traditional and new anti-reflective applications in which clarity of view is of paramount importance. Examples include museums and display cases, retail shop fronts, showrooms and a host of other applications such as panoramic restaurants, glass atria and sports stadia where, previously, an anti-reflective product was never an option.

  1. Solar Energy

Solar Energy panels offer alternative solutions to a range of energy requirements, from small scale domestic applications to large scale solar power stations, from cloudy northern rooftops to hot sunny deserts. Glass is an integral and important element of these solar panels. The NSG Group’s range of high quality products are used in the three leading solar technologies aimed at converting solar energy into electricity: thin film photovoltaics, crystalline silicon photovoltaics and concentrated solar power applications. In addition to the generation of electricity, the Group’s products are also used in solar applications that generate hot water.
NSG TEC is a group of products, including a comprehensive range of TCO (Transparent Conductive Oxide) coated glass, optimised to suit a variety of thin film photovoltaic technologies with different haze and conductivity levels. All NSG TEC products are manufactured using a patented chemical vapour deposition process to produce a durable, on-line coating that may be heat strengthened or fully tempered, providing complete flexibility for module production. Each of the products within the range is targeted at a particular thin film photovoltaic technology. The NSG TEC products are available in either standard or low-iron glass composition depending on the substrate/coating combination.
Pilkington Optiwhiteis an ultra-clear float glass with a very low iron content, which maximises the solar energy transmittance and, therefore, the efficiency of the module. The Group’s range of products includes the standard and well established low-iron Pilkington Optiwhite and Pilkington Optiwhite S, which has been developed especially for the solar industry, and therefore offers even greater solar transmission.
Pilkington Microwhite is Pilkington Optiwhite in its extremely thin version (glass thicknesses down to 1.0 mm). Because of their very high light transmittance and low absorbance Pilkington Optiwhite and Pilkington Microwhite are particularly suited to concentrator solar power technology too (i.e. solar mirrors).
Pilkington Sunplus is a glass specifically developed for use in crystalline silicon modules. This high performance low-iron glass has very high solar energy transmittance. When toughened, its strength and durability make it the ideal choice for this application.
The Pilkington Sunplus range of products includes:

  • Pilkington Sunplus SM: ultra high solar energy transmittance and low light reflectance due to a combination of a prismatic pyramidal pattern on one surface - S -, and a matt pattern on the other – M;

  • Pilkington Sunplus MM: ultra high solar energy transmittance and low light reflectance due to the matt pattern surfaces on both sides;

  • Pilkington Sunplus SM AR: ultra high solar energy transmittance with Anti-Reflective properties due to the application of an AR coating designed and optimised for crystalline silicon technologies.

The Pilkington Sunplus and Pilkington Optiwhite ranges are also ideal products for the cover plates of solar thermal collectors, as toughened, high transmittance glass is required for this application.

3. Other applications

The Group also manufactures a range of products aimed at special applications such as heated glass for commercial refrigeration, lighting, switchable glazing (electrochromics), appliance glass, computer screens, touch screens, static control, electronic signal shielding or other electro-optical and insulating applications.

The most popular product for these applications is NSG TEC™. There are a variety of NSG TEC™ products to meet specific needs, including

  • NSG TEC™ 15: the best choice for applications requiring passive condensation control and thermal performance with low-emissivity and clear colour-neutral appearance;

  • NSG TEC™ 7: offers the lowest resistivity value of the whole range - combined with relatively low haze, it can be used for a wide range of applications;

  • NSG TEC™ 35, NSG TEC™ 50, NSG TEC™ 70 and NSG TEC™ 250: used in heated glass applications - compatible with different power sources, these products combine thermal control with superior electro-optical properties;

  • NSG TEC™ SB: used as a substrate for off-line coated glasses, and provides a barrier layer to prevent sodium migration into the deposited film, particularly at elevated temperatures, leaving the performance of the off-line coating unaffected.

Pilkington Plateau is a high quality float glass made to extremely tight tolerances, giving the glass a special flatness demanded by the acrylic casting industry as well as other uses. It is offered in a range of different finishes (clear, satin and textured) to provide a variety of cast acrylic sheet surface finishes. Pilkington Plateau is ideal for acrylic casting and industrial applications.

Pilkington Microfloat is an extremely thin, high-grade float glass, which is manufactured to precise standards. It is made according to the highest specifications with very low thickness tolerances, to ensure flat and uniform products suitable for a variety of applications.
Pilkington Microfloat is traditionally used for the production of microscope slides, cosmetic mirrors, chromatographic plates, LCD photo masks, automotive and technical glass, PC display screens and tablet devices.
