Frequently Asked Questions
Are these shade sails waterproof?
No. These LOVE STORY sails are made from breathable HDPE fabric designed for UV protection and airflow, not to be waterproof. Expect rain to pass through; if you need rain protection, add a waterproof awning or secondary cover.
How should I measure my pergola before ordering?
Measure the distance between your intended attachment points and leave 0.5–1 ft of extra space for turnbuckles, straps or rope per the manufacturer’s guidance. Also account for the listed tolerance (up to ~4 inches) between D-rings when confirming final size.
Can I leave these sails up year-round?
Many users keep HDPE sails up seasonally or year-round with proper tensioning and periodic checks, but heavy storms and snow loads can damage fabric and hardware. If you experience severe weather, it’s safer to remove the sail or lower tension until conditions improve.
