Cool Area Sun Shade Sail 10x19x21.5 ft Right Triangle - Terra Red

In this review of the Cool Area Sun Shade Sail 10x19x21.5 ft right triangle, the bottom line is clear: this is a practical, attractive shade solution for homeowners who want reliable sun protection over a patio, pool or deck. The single biggest reason to buy is the solid shading performance from a single-piece, high density HDPE fabric that blocks up to 95% of UV and delivers an estimated 85% to 90% shading rate. Installation needs a small allowance for mounting hardware, but once in place the sail looks neat and cools covered spaces noticeably.

Key Features

• One-piece construction: Made from a whole shade fabric with no splicing seams, the sail offers a cleaner look and more consistent shade coverage than multi-seam alternatives.
• High-density HDPE fabric: The 100% new HDPE material provides superior UV protection and an effective 85% to 90% shading rate for cooler outdoor areas.
• Reinforced edges and D-rings: All edges are stitched and reinforced and corners include rust proof stainless steel D-rings to simplify attachment and resist fraying.
• Size tolerance for installation: The sail allows a fabric tolerance of about 4 in and installers should leave 0.5 to 1 ft of extra space for mounting accessories to achieve proper tension.
• Versatile outdoor use: The triangle shape works well over patios, pergolas, decks, pools, carports and balconies for both sun and partial rain protection.

Who It's For

The Cool Area triangle sun shade is aimed at homeowners and renters who want a low-cost, visually pleasing way to reduce sun exposure over a medium-sized outdoor area. It will suit people who can attach the sail to sturdy anchors such as posts, fences or building points and who appreciate a colored option like terra red that retains color in sunlight.

This sail is less appropriate for someone who needs a perfectly rigid canopy in extreme weather or a custom-fitted, non-elastic installation; because HDPE has elasticity and a 4 in tolerance, precise measurements and room for hardware are required and severe storms may shorten its lifespan.
