17 ft Triangle Sun Shade Sail Turquoise - Durable UV Block Canopy

In this review of the 17' x 17' x 17' Turquoise Triangle Sun Shade Sail from SHADESPEARE, the bottom line is simple: this canopy is for homeowners and outdoor hosts who need reliable sun protection with a clean, taut look. Our review found the biggest reason to buy is the sail's combination of lightweight virgin polyethylene construction and an engineered curved edge that prevents sagging, delivering effective cooling and up to 95% UV blockage for pools, patios, and driveways.

Key Features

• Measurement method: Sizes are taken from corner to corner so you know the span of coverage before mounting.
• Curved edges: Precisely calculated radian curves on the edges prevent sagging in the middle for a neater appearance and better tension performance.
• Material: Made from virgin polyethylene, the sail is light in weight yet has strong tensile strength for long-term outdoor use.
• UV protection: Provides up to 95% UV blockage and 90% visibility reduction, which helps keep outdoor spaces cooler and safer from sun exposure.
• Seasonal versatility: The fabric allows ventilation for summer cooling, offers some rain resistance, and helps reduce frost exposure at night.
• Warranty and customization: Backed by a 3-Year Limited Warranty and available for custom orders to fit unique spaces.

Who It's For

This shade sail suits homeowners with patios, pools, carports, balconies, or driveways who want a durable, high-coverage solution that stays visually tight when installed. It is particularly useful for those mounting sails between fixed points or among trees where ventilation and UV reduction are priorities.

Those who should look elsewhere include buyers needing a fully waterproof awning or rigid structure for year-round protection in heavy rain, and customers seeking an ultra-decorative fabric option - this is a functional, performance-first canopy rather than a decorative curtain.

Pros & Cons

Pros

• Strong tensile virgin polyethylene fabric gives lasting durability and light overall weight.
• Engineered curved edges reduce middle sagging for a tidy, professional fit.
• High UV blockage keeps pools and patios noticeably cooler and safer from sun exposure.
• Available customization and a 3-Year Limited Warranty add flexibility and reassurance.

Cons

• Hardware included receives mixed feedback, so buyers may need to source heavier-duty mounting gear for certain installations.
• Only slightly rainproof, so it is not ideal if complete waterproofing is required.
