Frequently Asked Questions

Q: Is this triangle shade sail truly waterproof for outdoor use?

A: The shade sail is water-resistant with a 400mm HH rating, meaning it effectively deflects light rain, drizzle, and morning dew. For maximum water runoff, install the sail at a 20–40° angle. It is not designed to withstand prolonged heavy downpours, and we recommend removing it during severe storms to prolong its lifespan.

Q: How much of the sun's UV rays does this shade sail block?

A: This shade sail blocks up to 98% of UV rays and provides a 90% shading rate. This significantly reduces ambient temperatures beneath the canopy, making outdoor spaces far more comfortable on hot, sunny days — and helping reduce air conditioning costs.

Q: How do I measure and install the triangle sun shade sail correctly?

A: Measure the area you want to cover and choose a sail size accordingly. Leave 1.5–2 ft of clearance between your fixing points (posts, walls, or trees) and the sail's D-rings to allow space for hardware, hooks, and the included free rope. The sail size refers to the straight-line stretched distance between D-rings. Because of the curved design, allow for a 4–6 inch tolerance on each side. Installing multiple sails in overlapping patterns is a great way to cover larger areas.

Q: Can I use this shade sail over a pool or patio furniture?

A: Absolutely. This shade sail is designed to be multifunctional and is perfectly suited for use over pools, patios, garden furniture, pergolas, carports, sandboxes, driveways, and more. Its UV-blocking and water-resistant properties make it a versatile year-round outdoor accessory.

Q: What material is the shade sail made from, and is it durable?

A: The sail is crafted from 100% polyester Oxford fabric (160 g/m²) with a PU coating. This combination delivers excellent resistance to water, tearing, and adverse weather. The curved edge design further enhances wind resistance and long-term durability. With proper care and seasonal storage during extreme weather, this shade sail will provide years of reliable outdoor performance.
