13ft x 16ft x 20.6ft Right Triangle Sun Shade Sail - 95% UV Block

In this review the focus is on a large custom right triangle shade sail designed for patios, gardens and commercial canopies. The bottom line: this sail is for anyone needing a heavy-duty, UV-blocking cover that actually cools outdoor spaces and stands up to sun and wind. Its single biggest advantage is the combination of 95% sun protection and robust construction, which delivers noticeable temperature reduction and long-term durability where a standard fabric canopy would fade or sag.

Key Features

• 95% UV blockage: The high-density 200 GSM HDPE fabric blocks up to 95% of harmful UV rays, protecting people and furnishings beneath the sail.
• Temperature reduction: The woven material reduces ambient temperatures by up to 15 degrees compared to unshaded areas, making outdoor seating noticeably cooler.
• Commercial-grade construction: Reinforced edges, double-layer stitching and stainless steel D-Rings ensure the sail resists fraying and holds up under sustained tension.
• Custom fit: Measured D-ring to D-ring to create a tailored canopy, with straight-edge customization available on request for neater installation lines.
• Air and water permeability: The permeable weave lets air and light through while shedding strong sun, reducing wind load and pooling during light rain.
• Installation flexibility: Can be mounted to trees, roofs, walls or poles and works with standard mounting hardware kits for many site configurations.

Who It's For

This shade sail suits homeowners, small business owners and property managers who need a large, durable cover for patios, play areas or outdoor dining. It is particularly useful where long-term UV protection and reduced heat are priorities and where a tailored size is required to fit an irregular space.

It is not ideal for buyers who need a fully waterproof awning for heavy, sustained rain or those expecting a lightweight temporary sun cloth; this product is a permeable, ventilated sail meant to reduce sun and heat rather than act as a watertight roof.

Pros & Cons

Pros

• High sun protection and measurable cooling from the 95% UV block fabric.
• Sturdy build with stainless D-Rings and reinforced double stitching for long service life.
• Custom sizing and shape options help achieve a neat, tailored installation.
• Permeable weave lowers wind load and avoids heavy water pooling in light showers.

Cons

• Because the fabric is breathable, it does not act as a fully waterproof canopy in heavy rain.
• Some customers note size expectations differ, so careful D-ring to D-ring measuring is essential to avoid surprises.

Frequently Asked Questions

Is this sail waterproof?
The sail is water permeable and designed to let water and air through; it is not a fully waterproof roof for heavy rain.

How should I measure for a custom fit?
Measure from D-ring to D-ring for each corner, allowing the recommended gap at mounting points and adjust for straight edge customization if requested.

Can it handle wind?
The permeable weave reduces wind load and customers report good durability in windy, sunny conditions when properly tensioned and anchored.
