ShadeMart 14ft x 20ft Grey Sun Shade Sail UPF50 Rectangle - Cool

In this review we look at the ShadeMart 14' x 20' Grey Sun Shade Sail to see who benefits most and why it stands out. The bottom line: the sail is for homeowners and small businesses who want an inexpensive, heavy-duty fabric canopy that reduces heat and blocks sunlight without trapping moisture. The strongest reason to buy is the combination of woven HDPE fabric and stainless steel corner D rings that deliver reliable shade, breathability, and long-term outdoor performance for patios, carports, and pool areas.

Key Features

• Woven HDPE fabric: provides a tough, tear-resistant surface that blocks up to 95% of harmful UV rays while remaining breathable.
• Stainless steel D rings: anchored to heavy duty white webbing for secure attachment and corrosion resistance in outdoor conditions.
• Water and air permeable: allows rain and wind to pass through, reducing wind load and preventing water pooling on the canopy.
• Temperature reduction: significantly lowers surface and shaded-area temperatures, making outdoor spaces more comfortable on hot days.
• Custom size options: available in multiple sizes and customizable dimensions so buyers can match specific patios, pergolas, or carports.
• Decorative rectangle styling: integrates with existing outdoor design and provides a clean, modern look for yards and patios.

Who It's For

The ShadeMart 14' x 20' Grey sail is best for homeowners, renters, and small commercial operators who need an affordable, durable shade solution for patios, pergolas, carports, or poolside areas and want a breathable canopy that tolerates wind and rain without sagging.

This is not the right product for buyers who require a fully waterproof cover or sealed shelter; the fabric is deliberately water permeable. Also, those needing a rigid, permanent structure should consider other solutions rather than a tensioned shade sail.

Pros & Cons

Pros

• Durable woven HDPE fabric resists tearing and lasts through seasons of sun exposure.
• Blocks a high percentage of UV to make shaded areas cooler and safer from sun damage.
• Stainless steel D rings and heavy webbing offer secure anchor points and corrosion resistance.
• Easy to tension to poles, trees, or walls with common hardware kits for flexible placement.

Cons

• Not waterproof, so it will allow rain through and is not a replacement for a hard roof.
• Size accuracy depends on careful measurement; some customers reported mixed experience with sizing.

Frequently Asked Questions

Is this shade sail waterproof?
The fabric is water permeable and breathable, so it will allow rain to pass through rather than shed water like a waterproof tarp.

Can it be attached to trees, poles, or a wall?
Yes; with the proper hardware kits the stainless steel D rings and webbing allow attachment to poles, trees, walls, or roofs.

Will it reduce temperature under the sail?
Yes; the woven HDPE and UV-blocking properties reduce temperatures in shaded areas, making them noticeably cooler on hot days.
