Zenith Advan (株式会社ゼニス・アドバン)

Zenith Advan supplies SmokeBarrier (スモークバリア), a lightweight smoke curtain wall for commercial facilities. It uses a special fibre in a dry-assembled frame, weighing about one-thirteenth of an equivalent glass panel and designed not to shatter in an earthquake. The page states the fibre holds non-combustible approval NM-3409, credited to the material maker 明電ケミカル (Meiden Chemical). Panels come in 500, 1,000 and 1,500 mm widths, up to 1,500 mm high, and custom curved shapes are available.
