11 ft x 17 ft x 20.2 ft Turquoise Right Triangle Shade Sail - UV Block

In this review of the 11 ft x 17 ft x 20.2 ft Turquoise Right Triangle Shade Sail from SHADESPEARE, the bottom line is simple: this is a practical, durable option for homeowners who need reliable sun protection over patios, pools, or driveways. The single biggest reason to buy is its combination of strong virgin polyethylene fabric and a precise curved-edge design that prevents sagging, offering consistent UV protection and a clean appearance over a full season.

Key Features

• Corner-to-corner measurement: Sizes are taken from corner to corner so buyers can plan mounting points and coverage accurately.
• Curved edges: Edges are made slightly curved using a calculated radian to reduce mid-span sag and maintain a taut, attractive canopy.
• High-performance fabric: Made of virgin polyethylene, the sail combines strong tensile strength with light weight for easy handling and long life.
• Sun and visibility blockage: Provides up to 95% UV blockage and around 90% visibility reduction to keep areas cooler and protect furnishings.
• Seasonal versatility: Offers shading and ventilation in summer, helps reduce frost overnight, and is slightly rainproof during light showers.
• Customizable with warranty: The product is available for custom orders and includes a 3-Year Limited Warranty for peace of mind.

Who It's For

This shade sail is aimed at homeowners and renters who need a cost-effective way to add large-area sun protection to backyards, patios, pools, or carports. It suits DIY installers who can use trees or fixed posts as anchor points and want a fabric that balances strength and light weight.

It is not ideal for locations with extended heavy rain or winter storms where a rigid roof is required, or for buyers who need fully waterproof canopies; the fabric is only slightly rainproof. Those needing a perfect, wrinkle-free architectural installation may prefer professionally tensioned systems.

Pros & Cons

Pros

• Effective UV shading that keeps pool and patio areas noticeably cooler.
• Curved-edge pattern prevents sagging and improves long-term appearance.
• Durable virgin polyethylene construction offers good tensile strength and value for money.
• Available for customization and backed by a 3-Year Limited Warranty.

Cons

• Hardware included receives mixed feedback, so buyers may want to upgrade fixings depending on their mounting situation.
• Only slightly rainproof, so it is not a substitute for a waterproof awning in heavy weather.
