18ft x 22ft White Rectangle Sun Shade Sail - 95% UV Blockage

In this review the focus is on a custom size 18' x 22' white rectangle sun shade sail meant for homeowners and small commercial spaces that need reliable sun protection without blocking airflow. The single biggest reason to buy is the balance of heavy-duty construction and measurable sun protection: made from 200 GSM HDPE fabric with up to 95% UV blockage, this sail cuts temperatures in shaded areas by about 15 degrees and keeps spaces comfortable while allowing breezes to pass through.

Key Features

• 95% UV protection: The 200 GSM HDPE fabric blocks up to 95% of harmful rays, reducing sun exposure for people and furniture beneath the sail.
• Temperature reduction: Tested to lower surface temperatures by up to about 15 degrees versus unshaded areas, making outdoor seating and play areas noticeably cooler.
• Durable construction: Reinforced edges, double-layer stitching and stainless steel D-Rings improve longevity and handle regular tension without fraying.
• Breathable and water permeable: The material lets air and light rain pass through so wind load is reduced and water does not pool on the canopy.
• Custom fit by D-ring measurements: The sail is made to order from D-ring to D-ring so it can be tailored to a precise installation area and preferred edge style.

Who It's For

This shade sail is aimed at homeowners, small business owners and property managers who need a durable, high-coverage sunshade for patios, play areas or outdoor dining where temperature control and UV protection matter. People who want a tailored fit and sturdy mounting hardware will appreciate the custom sizing and reinforced corners.

It is less suitable for those who require a fully waterproof canopy or a rigid structure; the sail is water and air permeable by design. Buyers who need off-the-shelf, exact pre-cut dimensions without ordering to make should verify measurements before purchasing to avoid fit issues.

Pros & Cons

Pros

• High UV rejection provides strong sun protection for people and outdoor furnishings.
• Durable 200 GSM HDPE fabric with reinforced stitching and stainless steel D-Rings adds longevity.
• Reduces temperature in shaded areas and still allows airflow so spaces stay comfortable.
• Custom sizing delivers a tailored fit when measured D-ring to D-ring for neat installation.

Cons

• As a permeable fabric, it is not completely waterproof and will not keep heavy rain fully out.
• One reported customer issue noted incorrect dimensions in a rare case, so careful measurement and confirmation are important.

Frequently Asked Questions

Is this sail fully waterproof?
The fabric is water and air permeable, so light rain will pass through and it will not hold water, but it is not a fully waterproof canopy.

How should I measure for a custom fit?
Provide precise D-ring to D-ring measurements; the sail is made to order based on those points for the best fit and tension.

What hardware is required for installation?
Stainless steel D-Rings are included on the sail and it pairs with standard mounting hardware kits; ensure at least 0.5 ft gap between D-Rings and poles or reduce by 1 to 1.5 ft per side as recommended for optimal performance.
