ShadeMart 18ft x 19ft Green Rectangle Sun Shade Sail - UPF50

In this review of the ShadeMart 18ft x 19ft Green Rectangle Sun Shade Sail the bottom line is simple: it is for homeowners and small business owners who want broad, breathable UV protection that stands up to outdoor use. The reviewer found the sail best when used over a patio, carport or pool area where airflow and shade are priorities; the woven HDPE fabric blocks up to 95% of UV rays while allowing water and air to pass through, so it reduces heat without becoming a tarp. Installation requires proper hardware and measuring, but the material and stainless steel corner D rings give confidence for long term use.

Key Features

• Material: Woven HDPE fabric delivers durable, tear-resistant shade that breathes and resists mildew better than some coated materials.
• UV Protection: The sail blocks up to 95% of harmful sunlight so shaded areas feel noticeably cooler by reducing direct sun exposure.
• Water Permeable: The breathable weave allows rainwater and air to pass through, preventing ponding and reducing wind load.
• Hardware Ready: Stainless steel corner D rings attached to heavy duty white webbing provide solid anchor points for proper mounting.
• Custom Sizes: The brand offers a range of custom sizes so buyers can match unusual spaces when they measure carefully.
• Decorative: The rectangle shape and available colors make the sail a practical shade solution that also complements outdoor decor.

Who It's For

The ShadeMart 18ft x 19ft rectangle sail suits people who need broad sun coverage with good airflow-patio owners, carport users, backyard poolside setups, and pergola improvisers will appreciate the combination of breathable shade and durable fittings. It is also a solid option for those who want an attractive, low-profile canopy that integrates with landscaping or outdoor furniture.

Those who should look elsewhere include buyers who need a fully waterproof canopy or a rigid, permanent roof replacement; because the fabric is intentionally water permeable this sail will not keep out heavy rain. Also, precision installers should note that custom sizing requires accurate measurements as sails can vary slightly by manual measurement.
