DuPont Glass Laminating Solutions has announced the commercial launch of SentryGlas N-UV ionoplast interlayer, which is an interlayer technology for durable architectural safety glass, with transmission of natural UV light into spaces containing special light requiring flora and fauna.

“Bringing full-spectrum light through laminated glass is proving attractive to botanists and other life science professionals,” said Ron Hull, DuPont Advanced Interlayer Business Director. “Our decision to fully commercialise and promote the product for this market reflects growing demand from around the world,” he added.

The latest project specified in high-UV-transmissive DuPont interlayer is South Korea’s National Ecological Institute (NEI) ‘Ecorium’ project (pictured): A 33,090m2 multi-domed, multi-climate-zone nature reserve and sustainability-minded study centre under construction in Seocheon-gun.

Past proof-of-concept projects include an Amazonian rainforest exhibit at the CosmoCaixa science museum in Barcelona, Spain; the ‘Tropenhaus’ rare species botanical garden in Berlin, Germany; and a bottlenose dolphin rehabilitation centre in Atlanta, USA.

For each project, DuPont manufactured its high-strength ionoplast interlayer without using UV blockers, allowing construction of laminated glass panels with improved transmission of shorter-wavelength UVA and UV-B ultraviolet light.
