13ft x 20ft x 23.9ft Red Right Triangle Sun Shade Sail - 95% UV Block

In this review the 13' x 20' x 23.9' red right triangle sun shade sail is evaluated as a tailored, heavy-duty option for homeowners and light commercial spaces that need reliable sun protection. The bottom line: it is best for anyone who wants a customizable, high-coverage canopy that blocks up to 95% of UV and noticeably cools a seating or play area. Installation takes some planning, but the durable 200 GSM HDPE fabric and reinforced corners make it a practical choice for patios, playgrounds and pergolas.

Key Features

• 95% UV blockage: The 200 GSM HDPE fabric provides strong sun protection for people and furnishings, reducing UV exposure in shaded zones.
• Temperature reduction: The sail can lower ambient temperature by up to 15 degrees vs unshaded areas to make outdoor spaces more comfortable.
• Custom sizing: Measured D-ring to D-ring so the canopy fits the intended footprint and can be remade for straight-edge preferences.
• Commercial-grade construction: Stainless steel D-rings, reinforced edges and double-layer stitching add tear resistance and long-term use potential.
• Permeable design: The fabric is water and air permeable, so it shades without trapping heat or creating strong wind loads on attachment points.
• Installation flexibility: Can be mounted to trees, roofs, walls or poles and works with standard mounting hardware kits.

Who It's For

This shade sail is well suited for homeowners, daycare operators and small commercial venues that need a large, durable triangular canopy to cover a specific area. Anyone who prefers a tailored fit will appreciate the made-to-measure D-ring sizing and the option to request straight edges for a cleaner look.

It is less suitable for people who want a temporary, ultra-low-cost shade solution or who cannot secure solid anchor points; proper installation and occasional maintenance are expected to reach the three-year assurance promise.

Pros & Cons

• Custom sizing improves fit and appearance for irregular spaces.

Cons

Frequently Asked Questions

Can I trim the sail or change the edge shape?
Contact the maker for straight-edge customization; standard orders are made to D-ring measurements for an accurate fit.

Will the sail keep rain off seating areas?
The fabric is water permeable so it provides shade and some rain deflection but is not fully waterproof like a solid tarp.

How long will it last in direct sun?
Construction is commercial-grade with a 3-year assurance, but customer experience varies and extreme sun exposure can shorten lifespan.
