20ft x 20ft x 28.3ft Right Triangle Sun Shade Sail - 95% UV Blockage

In this review of the 20' x 20' x 28.3' right triangle sun shade sail, the bottom line is simple: it's for homeowners or small commercial spaces who need reliable sun protection with a custom fit. The reviewer found the sail delivered substantial cooling and UV protection while remaining durable enough for season-long outdoor use. Easy to install and customizable from D-ring to D-ring, this shade sail is best when you want a tailored canopy that blocks most sunlight without creating a sealed roof.

Key Features

• 95% Sun Protection: The 200 GSM HDPE fabric blocks up to 95% of harmful UV rays to protect people and furnishings underneath.
• Temperature Reduction: The sail can lower ambient temperature by up to 15 degrees compared to unshaded areas, making patios and play areas noticeably cooler.
• Custom Fit: Measured D-ring to D-ring, the sail is made to order for a precise fit and offers straight-edge customization on request.
• Durable Construction: Reinforced edges, double-layer stitching and stainless steel D-rings improve longevity for repeated installation and seasonal exposure.
• Water & Air Permeable: The fabric sheds some water while allowing airflow, so it provides shade without trapping heat or creating a moist underside.
• Installation Flexibility: The sail mounts to trees, roofs, walls or poles and recommends a corner gap for optimal tension and performance.

Who It's For

This shade sail suits homeowners, cafes, playgrounds or poolside areas that need a durable, large-coverage shade solution that reduces UV exposure and lowers temperature. It works well where a semi-permanent canopy is desired and where you can anchor corners to trees, walls or poles.

Those who should look elsewhere include buyers who need a fully waterproof awning, a rigid structure, or a quick retractable solution; this product is a permeable fabric sail best for ventilated shade rather than a sealed shelter.
