Custom Size 13 ft x 13 ft Triangle Sun Shade Sail - 95% UV Blockage

In this review the focus is a custom size 13 ft x 13 ft x 13 ft triangle sun shade sail made from 200 GSM HDPE. The bottom line: this canopy is for homeowners or small businesses who want strong, breathable shade that blocks up to 95% of UV while lowering surface temperatures. The reviewer found the sail provides noticeably cooler shade, is straightforward to measure D-ring to D-ring for a tailored fit, and arrives with reinforced hardware that feels commercial-grade, making it a practical choice for patios, play areas, or cafe awnings.

Key Features

• 95% UV protection: Blocks most harmful rays with 200 GSM HDPE fabric to help protect skin and furnishings under the canopy.
• Temperature reduction: Lowers ambient temperatures by up to 15 degrees compared to unshaded areas for a more comfortable outdoor space.
• Customizable fit: Measured D-ring to D-ring so the sail can be ordered to suit irregular or specific mounting points for a cleaner installation.
• Durable construction: Stainless steel D-rings, reinforced edges and double-layer stitching improve longevity and resist fraying in regular outdoor use.
• Breathable and water permeable: The fabric sheds some water and allows airflow, avoiding the trapped-heat effect of solid tarps while maintaining shade.
• Flexible installation: Can be attached to trees, roofs, walls or poles and works with common mounting hardware kits for different setups.

Who It's For

This shade sail suits homeowners, small cafe owners, or landscapers who need a large triangular canopy that can be custom measured to specific D-ring points and who value strong sun protection and breathability. It is useful for patios, playgrounds, and outdoor seating where reducing heat and UV exposure matters most.

People who need a guaranteed decades-long fabric lifespan in extreme sun or those who want a fully waterproof roof should look elsewhere or consider additional protective solutions, since customers reported mixed long-term durability in continuous intense sun exposure.

Frequently Asked Questions

How should I measure for a custom order?
Measure from D-ring to D-ring at the mounting points and provide those dimensions; the sail is made to those measurements for a tailored fit.

Is the sail fully waterproof?
The fabric is water and air permeable, so it sheds some water but is not a fully waterproof solid canopy.

What mounting options are recommended?
Attach to trees, roofs, walls or poles using a standard mounting hardware kit and leave about 0.5 ft gap at corners or reduce by 1 to 1.5 ft per side as advised for tensioning.
