ColourTree CTAPRT10 Custom Right Triangle Shade Sail 18ft x 21ft x

In this review the ColourTree CTAPRT10 is assessed as a heavy duty, commercial-grade right triangle shade sail designed for patios, pools and carports. The biggest reason to consider it is its 190 GSM 100% virgin HDPE fabric treated with a UV stabilized compound, which the manufacturer says delivers far better longevity and sun resistance than recycled alternatives. This review focuses on build quality, UV protection, installation notes and real-world usefulness so you can decide if it fits a permanent or semi-permanent outdoor shade need.

Key Features

• 190 GSM virgin HDPE: The thick, non-recycled fabric gives a robust feel and resists tearing better than thinner or recycled sails.
• UV stabilized compound: Lab-tested for extended UV exposure so the material is less likely to dry, fade or crack over time.
• 95% UV blockage: The tightly woven mesh significantly reduces direct UV and lowers ambient temperature in the shaded area.
• Breathable woven design: Allows air and water to pass through to prevent pooling during rain and keep the covered area ventilated.
• Reinforced edges and D-rings: Double layered stitched seams and stainless steel D-rings help maintain shape and provide sturdy anchor points.
• 3 year limited warranty: Warranty provides added confidence under normal weather and usage scenarios.

Who It's For

The ColourTree CTAPRT10 works well for homeowners and small commercial operators who need a durable shade solution for patios, pools, balconies or carports and who prioritise sun protection and long-term fabric performance. Its large custom size and heavy duty construction suit installations where a strong, heat- and UV-resistant canopy is required.

It is less appropriate for buyers who need an off-the-shelf small sail or a waterproof tarpaulin-this product is breathable rather than waterproof, and installation requires separate hardware and proper anchor points, so renters or those without mounting options should consider alternatives.

Pros & Cons

Pros

• High-quality 190 GSM virgin fabric feels sturdy and made for prolonged sun exposure.
• Excellent sun blockage and breathability reduce heat and prevent water pooling.
• Reinforced seams and stainless steel D-rings aid durability and safe mounting.
• Backed by a 3 year limited warranty for everyday use in normal weather.

Cons

• Installation hardware is sold separately and must be chosen correctly for best results.
• Not waterproof by design, so it will not keep out heavy rain like a solid tarp.

Frequently Asked Questions

Is this sail waterproof?
No. The woven HDPE fabric is breathable and allows water to pass through to avoid pooling; it is not designed as a waterproof cover.

Does mounting hardware come with the sail?
No. Installation hardware kits are required and sold separately; use cable rope and proper shade sail hardware rather than nylon rope for best performance.

How durable is the fabric in sun exposure?
The 190 GSM virgin HDPE has been UV stabilized and lab-tested, and is intended to resist fading, drying and tearing far longer than recycled alternatives.
