ShadeMart 14 ft x 20 ft Blue Rectangle Shade Sail - UPF50 Sun Canopy

Our review of the ShadeMart 14 ft x 20 ft Blue Rectangle Shade Sail finds it best suited for homeowners and small commercial spaces that need a durable, breathable sun canopy. The biggest reason to consider it is its combination of woven HDPE fabric and stainless steel corner D rings, which deliver reliable sun protection while remaining water and air permeable. Installation is straightforward with the right hardware, and the fabric noticeably lowers ambient temperatures under the sail, making it a practical option for patios, carports, pergolas and poolside shade.

Key Features

• MATERIAL: Woven HDPE fabric resists fading and provides a lightweight yet sturdy surface that blocks most sun while staying breathable.
• UPF PERFORMANCE: Blocks up to 95% of harmful UV rays, helping reduce temperature and protect skin under the canopy.
• HARDWARE: Stainless steel corner D rings attached to heavy duty white webbing offer secure anchor points and greater longevity at attachment locations.
• BREATHABILITY: Water and air permeable construction allows rain to pass through and reduces wind load compared with solid tarps.
• CUSTOM SIZE OPTION: Available in a range of sizes so buyers can select or request dimensions that better fit their specific installation area.
• STYLING: Rectangle shape and color options make it easy to integrate the sail into existing outdoor decor while adding functional shade.

Who It's For

The ShadeMart rectangle sail is ideal for homeowners who want a cost-effective way to cool a patio, carport or pool area and for backyard entertainers who need a durable, breathable canopy that reduces UV exposure. It also suits DIY installers comfortable measuring an area and fitting a sail to posts, trees, or walls with an appropriate hardware kit.

This sail is not for buyers seeking a waterproof cover or a perfectly rigid structure; it is a breathable, tensioned fabric meant to let water through. If you need a waterproof shelter or a custom-fitted rigid roof, look for a different product designed specifically for those requirements.

Pros & Cons

Pros

• Durable woven HDPE fabric that maintains shape and resists UV degradation over time.
• Effective UV blocking up to 95%, producing a meaningful drop in perceived temperature beneath the sail.
• Stainless steel D rings and heavy webbing provide reliable attachment points for secure installation.
• Water and air permeable design reduces wind load and prevents pooling during rain.

Cons

• Not waterproof, so it will not keep heavy rain from passing through or provide a dry shelter.
• Size and shape can vary slightly due to manual measurements, so careful measuring and possibly ordering a custom size is important.
