7 ft x 11 ft x 13 ft Red Right Triangle Sun Shade Sail - Durable UV

In this review the 7 ft x 11 ft x 13 ft Red Right Triangle Sun Shade Sail is examined for homeowners and small-property managers who need a simple, effective way to reduce sun exposure. The bottom line: this triangular canopy works best where a lightweight, high-UV-blocking fabric is needed and where a slightly curved edge prevents sagging; it is a practical choice for patios, poolsides, driveways and carports because of its strong tensile virgin polyethylene construction and up to 95% UV blockage.

Key Features

• Corner-to-corner measurement: The dimensions are specified from corner to corner so buyers can plan mounting points and fit the sail to irregular outdoor spaces.
• Curved edge design: Edges are made slightly curved using a calculated radian to reduce sagging and keep a taut, attractive appearance after installation.
• High UV blockage: The fabric blocks up to 95% of UV and about 90% of visible light, providing effective sun protection and cooler shaded areas.
• Lightweight, strong material: Made from virgin polyethylene with good tensile strength, the sail is easy to handle while resisting tearing under normal tension.
• Seasonal versatility: The canopy helps with summer shading and cooling, offers ventilation, and provides slight rain resistance with some protection against night frost.
• Custom and warranty options: A 3-Year Limited Warranty and availability of custom orders let buyers adapt the sail to specific dimensions and needs.

Who It's For

The sail is aimed at homeowners, renters with outdoor space, and small property owners who need a low-cost way to shade a pool, patio, balcony or carport. Its lightweight polyethylene and easy handling make it a good fit for weekend installers who want effective UV protection without heavy hardware.

People who need fully waterproof covers, large commercial installations, or rigid permanent roofing should look elsewhere, since this product is only slightly rainproof and is designed as a flexible shade solution rather than a substitute for a solid canopy.
