Custom Size 18ft x 22ft White Rectangle Shade Sail - UPF50+ Cooling

In this review the custom 18' x 22' white rectangle shade sail earns its place for homeowners and light-commercial spaces that need reliable sun protection without a permanent structure. The single biggest reason to buy is the combination of heavy-duty 200 GSM HDPE fabric and 95% UV blockage, which delivers meaningful cooling and durable coverage for patios, playgrounds, or poolside seating. Installation is flexible enough for DIYers who can measure D-ring to D-ring for a tailored fit, and the included reinforced edges and stainless steel D-rings make the sail feel built to last.

Key Features

• 95% UV blockage: The high-density 200 GSM HDPE fabric blocks up to 95% of UV rays for safer outdoor time beneath the canopy.
• Temperature reduction: The sail lowers ambient temperature by up to 15 degrees compared to unshaded areas, creating a noticeably cooler spot for lounging or dining.
• Commercial-grade durability: Stainless steel D-rings and reinforced stitching give the sail a robust build that stands up to wind and frequent use.
• Custom fit: Made to measure from D-ring to D-ring so the canopy matches irregular spaces and minimizes sag with correct spacing.
• Air and water permeable: The breathable fabric reduces wind load and prevents puddling while still providing strong shade.
• 3-year assurance: The product ships with a three-year assurance that backs the material and construction quality.

Who It's For

This shade sail is best for homeowners, small businesses, and property managers who want a semi-permanent canopy that delivers significant sun protection and cooling without major construction. It suits patios, playgrounds, pool areas, pergolas, and outdoor seating where a tailored rectangle shape is required.

People who need a fully waterproof awning, or who cannot provide secure anchor points with the recommended spacing, should consider a different solution such as a rigid pergola or a framed canopy. Also, buyers who prefer pre-set off-the-shelf sizes without custom measurement should check standard-size options first.

Pros & Cons

Pros

• High sun protection from the 200 GSM HDPE fabric with 95% UV blockage.

• Durable build with stainless steel D-rings, reinforced edges, and double-layer stitching.
• Custom sizing gives a tailored fit for irregular spaces and better tensioning.

Cons

• Not fully waterproof; the permeable fabric lets water pass rather than shed it like a solid awning.
• Proper installation requires accurate D-ring measurements and suitable anchor points, which may be a hurdle for some users.

Frequently Asked Questions

Is this sail waterproof?
Answer. The fabric is water and air permeable, so it does not act as a fully waterproof tarp but prevents pooling and reduces wind load.

How should I measure for a custom fit?
Answer. Measure from D-ring to D-ring on the points where the sail will attach and allow recommended spacing gaps to ensure proper tension and fit.

How durable is the hardware?
Answer. The sail uses stainless steel D-rings and reinforced edges with double-layer stitching for enhanced durability and resistance to fraying.
