Frequently Asked Questions
Are these shade sails waterproof?
No. These LOVE STORY sails are breathable HDPE designed for UV protection and airflow; they will shed light moisture but are not waterproof. If you need full rain protection, pair an HDPE sail with a dedicated waterproof canopy or use waterproof polyester sails for the specific coverage area.
Can I mount a shade sail directly to my pergola beams?
Yes — you can attach sails to existing beams, but use proper stainless hardware (lag eye bolts with washers, pad eyes or beam plates) and leave 0.5–1 ft of slack for tensioning. Make sure attachment points are structurally sound and consider adding reinforcing plates if the beams are thin or aged.
How do I size a sail for good airflow under a pergola?
Choose a breathable HDPE sail that covers the needed area but allows gaps or a slight slope to promote airflow and drainage. Avoid full-enclosure installs; staggered or angled sails increase cross-breeze. Always factor in the manufacturer’s recommended accessory clearance (typically 0.5–1 ft) and account for the stated measurement tolerance.
