DuPont Glass Laminating Solutions announces the commercial launch of DuPont™ SentryGlas® N-UV ionoplast interlayer a new interlayer technology for durable architectural safety glass with unsurpassed transmission of natural UV light into spaces containing special light-requiring flora and fauna.

Vetri ad alta trasmissione UV per l’Ecoparco di SeoulLocated in Seocheon, Republic of Korea, the Ecoplex ecological park is a government led initiative to preserve the natural environment of the region and to create a national hub to gather various ecological valuables for advanced research and exhibition in Korea. The site was originally allocated to be developed as an industrial zone but due to its environmental values, the Korean government changed the plan and commissioned a design competition for the Ecoplex and its various facilities which was won by Samoo Architects & Engineers.

Planned as an eco-friendly building, the Ecorium is strategically designed to become a leading facility in regards to sustainability. For example, the alignment and the orientation of the various greenhouses were simulated to create an ideal environment depending on the climate zone the greenhouse would represent. Also, air-flow simulations were carried out so that natural ventilation effects could be maintained throughout the 4-seasons for necessary facilities. The sloped curtain-wall of each climate zones would gather rain-water for cooling & watering plants. With these various efforts, the whole facility was able reduce total energy consumption by approximately 10%. With a grand vision of becoming the hub for education and research on ecology, the Ecorium within the Ecoplex will play an important role in providing an opportunity for visitors to have a hands-on experience of the various ecological environments around the world and teach us the importance of our natural environments.

The latest project specified in high-UV-transmissive DuPont interlayer is South Korea’s National.

While invisible to humans, UV light is critically needed by many terrestrial and aquatic species for food identification, mating and display, proper growth and good health in environments as close as possible to their normal outdoor habitat.

Most architectural laminated glass includes UV blockers to protect interior fabrics and furnishings from discoloration and to avoid prolonged human skin exposure to the UV light rays. Compared with other interlayers available to the laminated glass industry, DuPont™ SentryGlas® N-UV is not cross-linked or cured, relying instead on intrinsic ionoplast stability to resist degradation or loss of clarity from extended exposure to sunlight.

Like normal ionoplast sheet, DuPont™ SentryGlas® N-UV offers up to 100 times the stiffness and 5 times the toughness of traditional safety glass interlayers, allowing for larger glass spans. This can further improve natural light transmission when used in combination with high-transmissivity glass.

Structural engineering advantages of SentryGlas® interlayer often allow for thinner glass and minimally supported glazing. The interlayer’s outstanding resistance to moisture ingress and chemical attack make it ideal for open-edged designs, even in warm, humid environments.

SentryGlas® N-UV interlayer is available in sheet form, in 1.52-mm (0.060-in.) thickness.

To help life science professionals and others explore product application ideas, DuPont has sample interlayer sheets available immediately for lamination and testing with user-specified glass for envisioned projects.
