ShadeMart 11 ft x 13 ft Grey Rectangle Sun Shade Sail - UPF50

In this review the ShadeMart 11' x 13' Grey Rectangle Sun Shade Sail is evaluated for homeowners and small businesses who need durable sun protection over patios, carports or pools. The bottom line: it is a heavy-duty woven HDPE shade that blocks up to 95% of UV, noticeably lowers outdoor temperatures, and installs with basic hardware. For anyone seeking a breathable, water-permeable canopy that reduces heat and resists sun damage, this shade sail delivers real value; shoppers who need a fully waterproof cover should look elsewhere.

Key Features

• Material: Woven HDPE fabric offers a balance of strength and breathability so the sail resists tearing while allowing air to pass.
• UV Protection: UPF50-level performance blocks up to 95% of harmful UV rays, reducing sun exposure and cooling covered areas.
• Water Permeable: The fabric is breathable and water permeable which prevents pooling and reduces wind load during rain.
• Hardware Ready: Stainless steel corner D rings attached to heavy duty white webbing provide reliable anchor points for common mounting kits.
• Custom Size Options: Available in a range of custom sizes so you can match irregular venues, but measure accurately because dimensions are manually produced.
• Decorative Styling: Rectangle shape and neutral grey color integrate with many outdoor decors while serving both functional and aesthetic roles.

Who It's For

The ShadeMart rectangle shade sail suits homeowners, rental properties, and small commercial spaces that need UV protection and airflow over patios, pergolas, carports or pool areas. It is a good choice when reducing temperature and sun exposure is the priority and when a permeable, low-pooling canopy is preferred over a solid waterproof roof.

It is not ideal for buyers who require complete waterproofing or a rigid structure; those who need exact precision-cut architectural panels should note that measurements are manually produced and the visible shape may vary slightly.

Pros & Cons

Pros

• High-density woven HDPE fabric feels durable and held up well in real-world use against sun and wind.
• Effective sun protection with UPF50-rated performance that cuts sunlight and heat noticeably.
• Stainless steel D rings and heavy webbing simplify secure installation when used with proper hardware.

Cons

• Not waterproof, so rain will pass through and it will not prevent water from reaching the area beneath.
• Size and rectangle regularity can vary due to manual measurements, so careful measurement is required before buying.
