Turquoise Sun Shade Sail Rectangle 14ft x 21ft - Breathable UV Blocker

Our review of the ShadeMart 14' x 21' Turquoise Sun Shade Sail finds it best suited for homeowners and renters who want a durable, breathable canopy to cut patio and carport heat without full waterproofing. The single biggest reason to buy is its fabric performance: the woven HDPE blocks up to 95% of harmful UV rays while remaining water and air permeable, so it lowers surface temperatures and avoids pooled water during light rain. Installation is straightforward with the reinforced stainless steel D rings and heavy duty webbing, making it a practical upgrade for outdoor shade on a budget.

Key Features

• Woven HDPE fabric: provides strong UV protection while remaining breathable so air can circulate and water will not pool on the canopy.
• Stainless steel corner D rings: securely anchor the sail to posts or walls and resist corrosion for longer outdoor life.
• Heavy duty white webbing: reinforces each corner, reducing tear risk and making the sail easier to tension tightly.
• Temperature reduction: the fabric can lower patio surface temperatures by around 10 to 15 degrees, improving comfort in direct sun.
• Custom sizing available: ShadeMart offers a range of custom sizes so buyers can order a sail that fits irregular spaces when measured correctly.
• Decorative rectangle shape: adds visual interest to patios, pergolas, and carports while integrating with existing outdoor design.

Who It's For

This sun shade sail is aimed at people who need reliable, breathable sun protection for patios, yards, pools, or carports and who prefer a solution that reduces heat without creating a waterproof canopy. It is a good match for DIY installers who can anchor the sail to posts, trees, or walls using suitable hardware kits.

Those who need fully waterproof coverage, or who expect complete rain protection for a permanent roof replacement, should look elsewhere; this sail is explicitly water permeable and designed to let water pass through rather than shed it.
