Why high floors flip
Higher floors mean higher wind load. Ordinary curtains have no rail constraint and balloon, derail or flip under wind. The fix isn't thicker cloth — it's fixing the fabric inside the rail.
Rail structure matters
Shulian runs the fabric inside the rail with an anti-derail zipper, resisting flip under strong wind. Third-party wind grading covers up to 35 m/s (JG/T 239-2009).
Pick fabric by floor
High-floor daily living can use Lingyong 816 sheer fabric for light and view; coast or mid-high-rise with frequent wind can use glass-fiber Yùfeng BP-6000 for a flatter, steadier sheet.
