ShadeMart 12 ft x 19 ft Turquoise Rectangle Sun Shade Sail - UPF50

In this review the ShadeMart 12 ft x 19 ft Turquoise Rectangle Sun Shade Sail is evaluated for homeowners and small commercial spaces that need reliable sun protection without trapping heat. The bottom line: this woven HDPE rectangle sail blocks up to 95% of harmful UV rays and remains breathable and water permeable, so it cools outdoor areas noticeably while avoiding pooled water. It is best for patio covers, carports, pergolas and poolside shade where durable fabric and stainless steel corner hardware matter.

Key Features

• Woven HDPE fabric: The high density polyethylene weave delivers a sturdy, tear-resistant canopy that reduces direct sun and lasts through regular outdoor use.
• UPF50 sun protection: Blocks up to 95% of harmful UV rays so shaded areas feel cooler and occupants get better protection from sun exposure.
• Water permeable design: Breathable construction allows rain and air to pass through, preventing water pooling and reducing wind load on the sail.
• Stainless steel D rings: Heavy duty stainless steel corner D rings attached to reinforced white webbing make secure installation possible with standard hardware kits.
• Custom sizing available: Multiple custom sizes are offered so the sail can be tailored to porches, decks, carports or irregular outdoor layouts when measured accurately.
• Rectangular styling: A clean rectangle shape in turquoise that doubles as a decorative element to enhance an outdoor space.

Who It's For

The ShadeMart rectangle sail is ideal for homeowners, property managers and small businesses wanting a cost-effective way to shade patios, carports, pergolas and pool areas while maintaining airflow. Its UPF50 protection and breathable fabric suit families and outdoor seating areas where lowering temperatures and sun exposure matter.

It is not for users who need a fully waterproof canopy or a perfectly rigid, tensioned architectural sail; the fabric is water permeable and sizing can vary slightly from manual measurements, so those requiring exact engineered dimensions or full waterproofing should consider alternative covers.

Pros & Cons

Pros

• High UV protection with UPF50 coverage reduces heat and sun exposure for occupied spaces.
• Durable woven HDPE construction and stainless steel D rings provide longevity and secure mounting.
• Permeable fabric prevents water pooling and improves breathability on hot days.
• Custom size options make it adaptable to many outdoor layouts.

Cons

• Not waterproof, so it will not provide full rain protection during heavy storms.
• Size and shape can vary slightly due to manual measurements, so careful measuring is required before ordering.

Our Verdict
