Frequently Asked Questions
How do I measure my patio for a rectangle shade sail?
Measure the usable shaded area, then add 6–12 inches at each corner for anchor hardware and tensioning. For uneven anchor points, sketch anchor heights and distances — you may need a custom size or multiple sails to avoid sagging.
Are HDPE shade sails waterproof?
No. HDPE sails are breathable and allow some water through, which reduces wind load and keeps things cooler. If you need a fully waterproof cover, look for coated polyester or vinyl awnings instead.
What hardware should I use to install a large shade sail?
Use stainless steel pad eyes, eye bolts, turnbuckles, shackles and heavy-duty D-rings. While many sails include ropes, upgrading to stainless steel hardware and adjustable turnbuckles improves tensioning and long-term durability — essential for large patios.
