ColourTree Custom Size 12ft x 18ft x 21.6ft Right Triangle Shade Sail

Our review of the ColourTree custom right triangle shade sail finds it best suited for homeowners and small businesses who need reliable summer sun protection with low maintenance. The single biggest reason to buy is the heavy 190 GSM 100% virgin HDPE fabric treated with UV stabilized compound, which offers strong resistance to fading and tearing after extended sun exposure while still allowing air and water to pass through. Installation requires separate hardware, but once mounted the sail delivers substantial cooling and lasting color.

Key Features

• 190 GSM virgin HDPE: Thick non-recycled fabric gives greater durability under sun exposure compared with recycled alternatives.
• UV stabilized compound: Laboratory-tested for long UV life so the sail resists drying out, tearing and fading over time.
• 95% UV blockage: Blocks most harmful ultraviolet rays and noticeably reduces temperature in shaded areas like patios or pools.
• Breathable woven fabric: Allows air and rainwater to pass through so there is no pooling and shaded spaces stay ventilated.
• Reinforced edges and stainless D-rings: Double layered stitched seams and heavy corner stitching improve structural strength and ease of hanging.
• Three year warranty: Limited warranty offers reasonable protection under normal weather and use.

Who It's For

This shade sail is ideal for homeowners with patios, balconies, poolside areas or carports who want strong sun protection and a durable fabric that holds color and shape in hot climates. It suits people who value a breathable fabric that reduces heat without trapping water after rain.

It is less suitable for buyers who need a complete mounting solution out of the box, since installation hardware and cable are sold separately, or for those expecting a lightweight temporary shade; this is a purpose-built, heavy duty commercial-style sail.
