Frequently Asked Questions
Are triangle shade sails waterproof?
Most triangle sails in this roundup are made from breathable HDPE; that lets air and some water pass through so they are cooling and won’t pond, but they are not fully waterproof. For rain protection choose a coated polyester or specifically waterproof awning fabric.
What hardware do I need to install a triangle shade sail?
You’ll need sturdy anchor points (walls, posts, or trees), stainless steel pad eyes or eyebolts, turnbuckles, shackles or snap hooks, and webbing or ropes. The sails include basic ropes, but upgrading to stainless hardware and turnbuckles gives better tension and longevity.
How do I measure for a triangle shade sail on a small patio?
Measure the three anchor points and note the available height differences. Leave 6–12 inches from each fixing point to the sail edge to allow for hardware and tensioning. Consider slope—mount one corner higher to shed water and reduce flapping in wind.
