Frequently Asked Questions
Are these shade sails waterproof?
Most SUNNY GUARD sails use breathable HDPE fabric that blocks up to 95% of UV and allows some water and air to pass. That reduces pooling and wind uplift but does not make the sail fully waterproof. If you need full rain protection, consider a dedicated waterproof canopy or adding a secondary waterproof layer.
How should I measure an odd-shaped patio for a custom sail?
Sketch the patio to scale and measure each anchor point precisely (corner-to-corner and along curves). Leave 0.5–1 ft extra per attachment for hardware and tensioning, and confirm with the maker how they interpret measurements. Photos and annotated diagrams speed up accurate custom cutting.
What hardware is best for long-lasting installations?
Stainless-steel pad eyes, turnbuckles and snap hooks are recommended for durability and corrosion resistance. Many SUNNY GUARD sails include ropes, but upgrading to stainless hardware and using proper masonry or structural anchors will extend the system’s life, especially in coastal or high-wind areas.
