1.d. Noise Control

With increasing traffic on the road, rails and in the air, noise insulation has become a very important topic. It is not a question of being a luxury anymore; it is essential that noise reduction is considered in the specification of glazing. With regard to employment law, comfort and medical necessity, noise insulation in building construction is an undisputed requirement to decrease stress and noise related illnesses.
Pilkington Optiphon is a high quality acoustic laminated glass that offers excellent noise reduction without compromising on light transmittance or impact performance. The desired acoustic performance can be achieved through combining various thicknesses of glass with a special PolyVinylButyral (PVB) interlayer. With a large variety of product combinations, it offers the opportunity to achieve specific noise reduction requirements.

Pilkington Optiphon can be combined with other Pilkington products for a multi-functional noise reduction monolithic glass or a multi-functional noise reduction Insulating Glass Unit, providing additional benefits such as thermal insulation, solar control or self-cleaning. It is the ideal choice of glass in any buildings where there is excess noise from road, rail or air traffic, or other sources such as factories or nightclubs.

1.e. Safety/Security

Innovations in the development of safety and security glasses have opened up new design opportunities, allowing both people to be protected from personal injury, and in the most extreme cases, buildings to be protected from various forms of attack without compromising levels of natural light and visibility.

The term ‘safety’ is applied to glazing used to reduce the risk of accident by impact, fracture, shattering, or in a fire. The term ‘security’ is applied to glazing which is able to withstand deliberate attacks of various kinds (physical or armed).
The Pilkington brand offers a wide range of sophisticated glasses to meet these increasing demands for protection of both people and property.
Pilkington Toughened Safety Glass is manufactured by subjecting final size, edge worked panes of glass to a heating and cooling treatment, whereby high compressive stresses are set up at the surfaces, with balancing tensile stresses in the centre. The high compressive surface stresses give Pilkington Toughened Safety Glass its increased strength, which is up to five times stronger than ordinary annealed glass of the same thickness.
Pilkington Optilam is a laminated glass produced by combining two or more sheets of float glass with one or more interlayers, the most popular being the PVB interlayer. The interlayers ensure the integrity of the glass by holding the broken pieces in place should any damage occur. In fact, glass fragments adhere strongly to the interlayer, while the resistant cushioning effect dissipates the energy. Pilkington Optilam can be enhanced when combined with other Pilkington products to provide additional benefits such as self-cleaning, solar control or thermal insulation.
The various performance levels of Pilkington Optilam are achieved by simply changing the number and thickness of each layer of glass and PVB interlayer. By doing this, Pilkington Optilam can be used for a wide range of applications, whether it is for safety (glazed building entrances, internal doors, overhead and roof glazing, swimming pools and windows in critical risk locations), security (applications which display valuable goods, such as museums or in banks or building societies, as well as safety glazing in hospitals and prisons) or bullet resistance (high risk buildings such as banks, post offices, building societies, embassies, cash offices, military establishments and VIP residences).
1.f. Self-cleaning
Thanks to its revolutionary coating, the Pilkington Activ on-line coated self-cleaning range of glasses stays cleaner, all year round. Their unique dual-action coating uses the forces of nature to help keep the glass free from dirt, giving not only the practical benefit of less cleaning, but also clearer, better-looking windows.
Pilkington Activ is available in combination with other products from the Pilkington range to provide additional benefits such as solar control (Pilkington ActivBlue, Pilkington Activ Neutral, and Pilkington Activ Suncool), thermal insulation (Pilkington Activ Optitherm), impact resistance or increased security (Pilkington Activ Optilam) and noise control (Pilkington Activ Optiphon).
1.g. Decoration
As well as offering functional benefits, glass is also used to enhance the appearance of the environment. The Pilkington range of decorative glass turns it from a basic construction material into a means of adding style and elegance. Incorporating decorative glass can add privacy and meet any requirements, whether they are aesthetical or practical.
Pilkington Optifloat Opal is an acid-etched product suitable for internal and external use. It is a translucent glass that creates an attractive finish for windows, partition walls, glass doors, furniture, shelving, wall cladding and many more applications, offering all the diffused natural light of a translucent glass, but with none of the drawbacks.
Pilkington Spandrel glasses are toughened safety glasses that are mostly used in non-vision areas of façades. The most popular range is Pilkington Spandrel Glass Coated, a toughened range of glasses coated with a metallic coating specially developed for the Pilkington Suncool product range. The Pilkington Spandrel Glass range offers a number of options for use with curtain wall applications that allow the building exterior to be fully glazed. The products can also be used for interior design and furniture.
Pilkington Texture Glass is a range of rolled patterned glasses, one surface of which has a specific pattern or design impressed into the surface, which creates a decoration. The patterned glasses allow the passage of light but depending on the depth and configuration of their pattern, varying degrees of obscuration are obtained. The range offers a wide selection of alternatives, meeting both functional and aesthetic requirements, and may be used for privacy in commercial, industrial and residential buildings. They may also be used for decorative purposes in applications such as doors, partitions and balustrades.
1.h. Glass Systems

Glass can be used to create building interiors which connect occupants with the external environment, combining unbroken views and high levels of natural light with the comfort and safety of the internal environment.

The Pilkington range of glass systems allows designers and specifiers to transform yards into cosy interiors, enclose private and public outdoor areas under glass roofs and build stunning glass façades.

Pilkington Planar is the world’s leading structural glazing system. It allows architects immense flexibility in the appearance of façades, while incorporating all of the functionality required from windows in today’s buildings. Utilising stainless steel fittings housed in countersunk holes to fix the glass façade back to the structure, Pilkington Planar results in a fully engineered system with the minimum of structure and the maximum visual clarity. A silicone seal between adjacent panels also provides weatherproofing. Pilkington Planar can incorporate most Pilkington glass types, including the range of solar control, low-emissivity and Pilkington Activ self-cleaning glasses.

Pilkington Profilit is a range of alkali cast glasses in a U-shape, which is produced according to EN 572, Part 7, using the machine rolling process. The products are translucent, but not transparent, with or without a patterned surface on the outside, and have the quality features of cast glass.

The end result is a wall that obscures vision but allows light to pass through. Pilkington Profilit products can be used in interior or exterior applications, and the "U-shaped" channels can be installed either vertically or horizontally.

The glasses are available in a variety of colours and textures with varying translucency, allowing for the passage of natural light without the loss of privacy. Pilkington Profilit products can offer thermal insulation and solar control, as well as sound reduction; they provide the most cost-efficient glass wall systems available. The products come in various patterns. The range of products can be single glazed for interior use or double glazed for exterior applications.

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.
