ShadeMart 13 ft x 20 ft Blue Sun Shade Sail - UPF50 Rectangle

In this review the ShadeMart 13' x 20' Blue Sun Shade Sail is assessed for homeowners and small-business owners needing affordable, breathable sun protection. The bottom line: this rectangle shade sail is best for those who want strong UV blocking and airflow rather than a waterproof canopy. Made from woven HDPE with stainless steel corner D rings, it delivers solid sun protection and durability while allowing water to pass through, which keeps it cooler and easier to maintain than coated fabrics.

Key Features

• Material: Woven HDPE fabric resists fading and provides a lightweight, durable covering suitable for long-term outdoor use.
• UV Protection: UPF50 level fabric blocks up to 95% of harmful UV rays to significantly lower temperatures beneath the sail.
• Breathability: Water permeable construction lets rain and air pass through, reducing pooling and wind load on the installation.
• Hardware Ready: Stainless steel D rings attached to heavy duty webbing give secure attachment points that work with common shade hardware kits.
• Custom Options: Custom sizing is available so the sail can be tailored to patios, carports or pergolas when standard sizes do not fit.
• Style: Rectangle shape and color choices let the sail act as both functional protection and an outdoor design element.

Who It's For

The ShadeMart 13' x 20' sail suits homeowners, small cafes and backyard enthusiasts who need reliable UV protection and improved comfort without trapping heat under a waterproof canopy. It is particularly useful over patios, play areas, pools and carports where airflow and drainage are priorities.

Customers who need a fully waterproof cover or a perfectly exact industrial rectangle should look elsewhere; this style is explicitly water permeable and sizes can vary slightly due to manual measuring, so measure carefully before ordering.

Pros & Cons

Pros

• High UPF rating blocks most harmful sunlight and lowers temperatures beneath the sail.
• Woven HDPE fabric is durable and resists fading in outdoor use.

• Stainless steel D rings and heavy webbing make attachment straightforward with common hardware kits.

Cons

• Size and shape can vary slightly with manual measurement, which may require careful ordering and installation adjustments.
