ColourTree Custom Size 18ft x 20ft x 26.9ft Turquoise Right Triangle

In this review the ColourTree CTAPRT10 custom right triangle sun shade sail is assessed for homeowners and small businesses who need reliable sun protection in a corner or triangular layout. The single biggest reason to buy is its heavy-duty 190 GSM virgin HDPE fabric treated with a UV stabilized compound, which delivers long-lasting, breathable shade and blocks up to 95% of harmful UV. This sail feels substantial, resists fading, and is designed for outdoor use where sun, heat and occasional rain require a durable, low-maintenance canopy solution.

Key Features

• 190 GSM virgin HDPE: The thick, non-recycled material provides a robust, long-lasting canopy that resists tearing and premature wear under sun exposure.
• UV stabilized compound: Factory UV treatment prevents the fabric from drying out and fading, helping the sail maintain strength and color after extended sun testing.
• 95% UV blockage: The tightly woven fabric significantly reduces sunlight and heat in shaded areas, making patios, pools and balconies noticeably cooler.
• Breathable design: Woven construction allows air and water to pass through, preventing water pooling and reducing wind stress on attachment points.
• Reinforced edges and hardware-ready corners: Double layered stitched seams and stainless steel D-rings give secure anchor points and resist fraying at the corners.
• 3 year limited warranty: The included warranty covers normal weather and use, offering additional peace of mind for outdoor installations.

Who It's For

The sail is best for homeowners, pool owners and small commercial spaces that need a strong, colorful shade solution installed between walls, poles or trees where a right triangle shape fits the layout. It suits people who value durable materials and UV performance and who plan to leave the sail in place for seasons at a time rather than moving it frequently.

Those who should look elsewhere include buyers who need a complete mounting kit included or who prefer a waterproof solid canopy; installation hardware is sold separately and nylon rope is explicitly discouraged. Also consider a different style if you require precise pre-cut corner fittings for an irregular structure.

Pros & Cons

Cons
