A large opening folding door that balances the opposing elements of "openness" and "airtightness" with high specifications.
The "Istar Curtain Opening" is a large opening folding door that achieves performance equivalent to building sashes in terms of airtightness, watertightness, wind pressure resistance, and sound insulation, all meeting JIS standards. By narrowing the frame and expanding the maximum width of a single panel to 683.5mm, it ensures better views and the influx of natural light. Additionally, by adopting a flat bottom frame, it eliminates boundary steps and enhances safety. We offer four types, including the "Corner Type," which provides an open feeling similar to being outside without corner posts, and the "Fire Protection Equipment Type," which has obtained certification as a fire protection device. 【Features】 ■ Full-open stopper that is safe even in strong winds ■ Handle designed with consideration for security and safety ■ Ministry of Land, Infrastructure, Transport and Tourism certified fire protection equipment EB-0716 (Fire Protection Equipment Type) ■ No corner posts remain when fully opened (Corner Type) ■ Stainless steel rail can be implemented (Stainless Steel Rail Type) For more details, please refer to the catalog or feel free to contact us.
