Frequently Asked Questions
Are these shade sails waterproof?
No — these Sunny Guard sails use breathable HDPE fabric designed to block UV and allow air and some water to pass through. They cool areas effectively but are not intended as rainproof covers.
Do I need special hardware to install a shade sail?
Basic ropes are included, but for long-term tension and wind resistance you should use stainless steel anchors, pad eyes and turnbuckles. Proper hardware prevents sagging and extends the sail’s life.
How do I measure for a custom shade sail?
Measure the distance between anchor points, then subtract 0.5–1 foot per edge to allow room for attachment hardware and to tension the sail properly. Confirm angles and clearances before ordering a custom size.
