17 ft x 20 ft x 26.2 ft Green Right Triangle Sun Shade Sail - UV Block

Our review of the 17' x 20' x 26.2' green right triangle sun shade sail finds it best suited for homeowners and small businesses seeking a durable, high-coverage canopy that cuts sun and heat. The single biggest reason to buy is its combination of heavy-duty virgin polyethylene fabric and a curved-edge design that maintains tension and prevents mid-sheet sagging, delivering reliable shade and a neat installed appearance.

Key Features

• Corner-to-corner sizing: Measurements are taken from corner to corner so you know the true span when planning installation and coverage.
• Curved edge design: Edges are slightly curved using a calculated radian to prevent sagging and keep the sail taut for a cleaner look and better water runoff.
• High UV blockage: The fabric blocks up to 95% of UV rays while still allowing airflow, which helps keep shaded areas cooler on hot days.
• Lightweight, strong material: Made from virgin polyethylene for strong tensile strength without heavy weight, making handling and mounting easier.
• All-season performance: Provides shading and ventilation in summer, anti-frost protection at night and light rain resistance during brief showers.
• Custom orders and warranty: Custom sizes are available and the product includes a 3-Year Limited Warranty for added confidence.

Who It's For

This shade sail is ideal for homeowners with patios, pools, driveways, carports or gardens who need broad, angled coverage from a single triangular sail. Small businesses with outdoor seating or walkways will also appreciate the cooling and UV protection benefits provided by a large, right-triangle canopy.

Those who should look elsewhere are buyers who need fully waterproof awnings for prolonged heavy rain, or anyone seeking rigid frame umbrellas or motorized retractable solutions rather than a tensioned fabric sail. If you require a perfectly flat membrane rather than a curved-edge tensioned sail, consider an alternate style.

Pros & Cons

Pros

• Excellent UV protection and cooling thanks to fabric that blocks up to 95% of sun rays.
