Sun Shade Sail 13ft x 14ft Turquoise Blue Rectangle - Cool UV

In this review the SUNLAX 13' x 14' turquoise blue rectangle shade sail is assessed for backyard and patio use; it is best for anyone who needs a simple, durable way to cut bright sun and UV exposure without blocking airflow. The biggest reason to buy is the material: a high-density polyethylene knit that blocks up to 95% of UV rays while still allowing cooling breezes and light rain to pass through, so it creates comfortable dappled shade rather than a sealed canopy.

Key Features

• High-density polyethylene: provides 90%-95% shading for the colored series and blocks 95% of UV, significantly reducing sun exposure.
• Permeable knit: lets air flow and raindrops penetrate so the covered area stays cooler and avoids trapped heat under the sail.
• Double-stitched seams: finished edges and reinforced stitching improve long-term durability at stress points.
• Anti-rust D-rings: four metal D-rings, one at each corner, make anchoring straightforward and resist corrosion over time.
• Curved edge design: curved sides reduce sagging and improve shade coverage and visual appearance.
• Installation guidance: requires 0.5-1 ft of extra space to attach hardware, giving flexibility for different mounting setups.

Who It's For

The SUNLAX shade sail is ideal for homeowners with patios, decks, pergolas or play areas who want effective sun and UV reduction without a heavy, waterproof structure. It suits people who prefer a breathable shade that cools the space and provides a pleasing dappled light effect.

It is less suitable for those who need a fully waterproof cover or precise dimension tolerances for indoor structures; the fabric is not waterproof and sail lengths are measured from D-ring to D-ring with a tolerance up to about 4 in, so exact-fit installations should plan accordingly.

Pros & Cons

Pros

• Blocks most UV and reduces heat thanks to a high-density knitted fabric and a 90%-95% shading rate.
• Permeable design and curved edges prevent a stuffy feel and reduce sagging for a neater look.
• Easy to anchor with included cords and anti-rust D-rings, and the seams are double-stitched for durability.
• Customers report it looks great on decks and offers better shade than umbrellas in many cases.

Cons

• The sail is not waterproof, so it will not keep an area dry in steady rain.
• Length is measured between D-rings with a tolerance, so exact sizing requires planning and possibly custom sizing.

Our Verdict

The SUNLAX 13' x 14' turquoise rectangle is a practical, value-oriented shade sail for patios, decks and pergolas when the goal is sun and UV reduction while maintaining airflow. It is well made with reinforced seams, D-rings and a curved edge to limit sag; buy it if you want breathable, reliable shade and are not seeking a waterproof solution.

Frequently Asked Questions

Is this shade sail waterproof?
No. The fabric is permeable to allow air and light rain to pass through, so it does not provide waterproof protection.

How much space is needed for installation?
Leave about 0.5-1 ft between the fixing point and the sail to allow for mounting hardware or rope; accessories are sold separately.

Will it block UV and heat?
Yes. The high-density polyethylene knit blocks up to 95% of UV rays and provides substantial shading to reduce heat in the covered area.
