Frequently Asked Questions
Are triangle shade sails waterproof?
Most triangle sails reviewed here use breathable HDPE which blocks UV and allows water to pass through — that means they cool well and resist wind uplift, but they are not fully waterproof. If you need full rain protection choose a different waterproof material or set up a drainage slope.
What hardware do I need to install a shade sail?
Basic installs include rope and the sail's D‑rings, but for secure, long-lasting installs use stainless steel pad eyes, turnbuckles and snap hooks. Many customers recommend upgrading to stainless anchors to avoid corrosion and to tension the sail properly.
How do I pick the right size sail for my patio?
Measure your mounting points and leave 6–12 inches extra for tensioning and hardware. Consider the angle and height: triangle sails should be mounted at varying heights to shed rain and avoid pooling. If in doubt, choose a customizable size option to get an exact fit.
