14 ft x 16 ft x 21.3 ft Red Right Triangle Sun Shade Sail - UV Block

In this review of the 14' x 16' x 21.3' Red Right Triangle Sun Shade Sail, the bottom line is simple: it is best for homeowners and renters who need a large, durable triangular canopy that blocks sun and reduces heat over patios, pools, and carports. The reviewer found the shade most valuable for its measured corner-to-corner sizing and engineered curved edges that prevent mid-span sagging, plus a fabric that offers strong tensile strength and high UV blockage, making it a practical, long-lasting solution for outdoor shade needs.

Key Features

• Corner measurement and curved edges: The sail is measured from corner to corner with precisely calculated radian curves to reduce sagging and maintain a neat, tensioned appearance.
• Durable virgin polyethylene fabric: The material combines light weight with strong tensile strength so the canopy holds tension and resists tearing under normal outdoor use.
• High UV and visibility blockage: The fabric claims up to 95% UV blockage and 90% visibility blockage, which helps keep shaded areas cooler and reduces sun exposure.
• Seasonal versatility: The sail provides summer shading and cooling, nighttime anti-frost benefit, and some rain resistance in light showers, making it useful across seasons.
• Customizable and warranted: The product is available for custom orders and includes a 3-Year Limited Warranty for added purchase confidence.

Who It's For

The shade sail is ideal for homeowners with a backyard, patio, pool area, driveway or carport who want a large triangular canopy that stays taught and looks tidy. It also suits people who need a strong, lightweight fabric that blocks a high percentage of UV without completely cutting airflow so the shaded area remains ventilated.

It is less suitable for buyers who require a fully waterproof awning for heavy rain or for those who need a structure with built-in poles and complex hardware; some customers report mixed experience with the supplied hardware, so those wanting an all-in-one mounting solution may prefer to purchase dedicated anchors or fittings separately.

Pros & Cons

Pros

• High UV blockage and ventilation combine to keep pools and patios noticeably cooler.
• Engineered curved edges and corner-to-corner sizing reduce sagging and improve appearance.
• Lightweight yet strong virgin polyethylene resists wear and provides good tensile strength.
• Custom order option and a 3-Year Limited Warranty add flexibility and reassurance.

Cons

• Only slightly rainproof in light showers, so it is not a substitute for a waterproof roof.
• Hardware included receives mixed feedback, so some buyers may need to upgrade fittings for long-term installation.
