Custom Size 12ft x 17ft Red Rectangle Sun Shade Sail - 95% UV Blockage

In this review the focus is the custom size 12' x 17' red rectangle sun shade sail, aimed at homeowners and light commercial users who want reliable sun protection with a tailored fit. The biggest reason to consider this shade is its combination of heavy-duty 200 GSM HDPE construction and claimed 95% UV blockage, which delivers measurable cooling and durable outdoor coverage when a standard umbrella or pergola is not practical.

Key Features

• 95% UV Protection: The 200 GSM HDPE fabric blocks up to 95% of harmful UV rays, offering safer shade for long outdoor exposure.
• Temperature Reduction: The sail can lower ambient temperature by up to 15 degrees versus unshaded areas, making patios and play areas more comfortable.
• Heavy Duty Construction: Reinforced edges, double-layer stitching and stainless steel D-rings improve longevity under tension and repeated use.
• Water and Air Permeable: The breathable weave sheds some water and allows airflow to reduce heat buildup and minimize wind load.
• Custom Fit: Made to measure from D-ring to D-ring so the 12' x 17' panel fits a designated space precisely without excess material.
• 3 Year Assurance: A three year assurance period provides added confidence in the product's durability and manufacturing quality.

Who It's For

This shade sail is best for homeowners, landscapers or small venue operators seeking a permanent-looking canopy that can be mounted to trees, roofs or posts. The custom sizing works well where off-the-shelf sails or umbrellas would leave gaps or create awkward overhangs.

It is less suited for those who need a fully waterproof awning or who require rigid framing; the sail is water and air permeable rather than fully waterproof, and installation requires secure anchor points and an understanding of tensioning.

Pros & Cons

Pros

• High sun protection from the 200 GSM fabric blocks most UV exposure for safer outdoor use.
• Noticeable cooling effect, with up to 15 degree reduction reported in shaded areas.
• Durable fittings and reinforced stitching reduce fraying and extend service life.
• Custom sizing allows a tailored look and fit for irregular or specific spaces.

Cons

• Not fully waterproof due to the breathable HDPE weave, so heavy rain may pass through or drip.
• Installation requires planning for proper D-ring gaps and sturdy anchor points, which may need additional hardware or labor.

Our Verdict

Frequently Asked Questions

Is this sail fully waterproof?
The sail is water and air permeable, so it sheds some water but is not fully waterproof like a solid canopy.

How should I measure for a custom sail?
Measure from D-ring to D-ring and allow the recommended gap of at least 0.5 ft at each corner, adjusting by 1 to 1.5 ft per side if needed for tension.

What mounting points are required?
Secure anchor points such as sturdy posts, walls, roofs or trees are needed along with appropriate mounting hardware to maintain tension and prevent sagging.
