Energy savings are an essential part of any new or renovated building. These can be obtained by means of insulation, special glazing and the use of particular materials.

Trosifol, a division of the Kuraray Group, presented products, which guarantee higher efficiency with regards to sound control, and even increasing safety during energy blackouts with its new PVB film, which is self-luminous in the dark.

Founded in 1926, the Kuraray Group, with headquarters in Tokyo, Japan, and workforce of about 7,500 employees, is the world’s biggest producer of water-soluble synthetic polyvinyl alcohols - an initial product for many applications in day-to-day living.

This activity, pursued in the Chemicals and Resins division, accounts for a considerable proportion of overall business. These products are further processed for a variety of applications, including paints and printing inks, computer housings, food packages, LCD monitors and also pharmaceutical products.

In Europe, operating business, sales and the production of chemical specialities are handled by Eval Europe in Antwerp and “Kuraray Europe GmbH, in Frankfurt. The Trosifol division, which joined Kuraray Europe at the beginning of 2005, is firmly integrated in the strategy of the internationally successful Kuraray Group.

Kuraray Europe is the leading supplier of polyvinyl alcohol (PVA) and polyvinyl butyral products in Europe. Both of these specialized chemical products are crucial for the production of paper, textiles, packaging materials and PVB film for laminated safety glass as well as for paints, printing inks, adhesives, cosmetics and ceramics.

Lumineo marks a new departure for Trosifol in its appeal to architects. As the leading supplier of PVB films in European architectural glazing, the PVB manufacturer of the Japanese Kuraray Group is targeting this new self-luminous PVB film directly at architects, designers and creative minds in order to inspire new trends in the design of architectural glazing.

The new film product achieves its effect with a special formulation (European patent pending). Lumineo is inspirational, the basis of new ideas. At the same time, Lumineo meets the criteria of the German Lists of Construction Products of the DIBt (German Institute of Construction Technology).

Safety certificates to EN 356 and EN 12600 are available on request. A test report on the afterglow properties of Lumineo is also obtainable (BAM, DIN 67510-4, sub-classification A, Ref. VIII 1E 2077 of March 2009 for “Phosphorescent pigments and products”, such as emergency exits and escape routes).

Developed to European standards for safety glass, it can be combined with other Trosifol films to modify optical and acoustic properties, thus opening up entirely new creative scope for the design of laminated safety glass. Lumineo reduces the need to install additional light sources in public areas for emergency situations, e.g. power failures.

By combining safety and design scope with light transmittance values of up to 60 per cent, Lumineo is ideal for use in interior architecture and in public buildings in which design and safety are of equal importance.

Lumineo can be employed on façades, roofs, balustrades and balconies and in any glazing applications at all, indoors and outdoors. Trosifol® Lumineo is available in standard widths of 1,000, 1,600 and 2,250 millimetres, each in a thickness of 0.76 millimetres. The roll lengths are 20 metres and 200 metres and are supplied with a PE interleaved film.

Decisive plus for greater efficiency and less noise

Sound insulation with Trosifol Sound Control (SC) is now better than ever before. At Glasstec 2010 in Düsseldorf, the Trosifol Division of Kuraray Europe GmbH presented an improved version of its own sound protection film, the new SC+. It significantly enhances the efficiency of the commercial-scale production of acoustic laminated safety glass.

The improved efficiency of the new multi-layer Trosifol SC+ PVB film will particularly benefit high-performance processors specializing in jumbo widths. Combinations with white translucent, coloured or colourless Trosifol PVB films are of course possible. The new SC+film thus extends the existing Trosifol sound protection range to include a productivity-boosting variant without compromising on the accustomed outstanding optical properties of clarity, transparency and light stability.

Trosifol SC+ is a multi-layer film developed specifically for efficient processing and displays its huge advantages particularly in the high-per-formance processing of jumbo widths. This makes it the ideal complement to Trosifol’s existing sound protection range.

It goes without saying that the outstanding sound insulation values combined with the familiar safety characteristics are retained by the film’s new multi-layer composition. In composition 44.2, laminated safety glass satisfies safety class P2A in conformity with EN 356 and class 1B1 in conformity with EN 12600. Test certificates from MPA Darmstadt can be furnished on request.

In corresponding ISO glazing and depending on composition, a laminated safety glass (LSG) produced with SC+ achieves sound insulation values of up to 50 dB. This enables glass processors to produce LSG with outstanding acoustic and safety characteristics in a process identical to that for the proven Trosifol BG range.

Trosifol SC+ is available in a roll width of 3.21 metres and a roll length of 230 metres as a cooling film. It is 0.76 millimetres thick.
