ColourTree CTAPRT16 Right Triangle Sun Shade Sail 18ft x 21ft x 27.7ft

In this review of the ColourTree CTAPRT16 right triangle sun shade sail, the bottom line is simple: ideal for homeowners or small commercial spaces that need reliable UV protection and long-lasting fabric. The sail is made from 190 GSM 100% virgin HDPE tested for UV exposure, so the biggest reason to buy is its durability under strong sun and its ability to block heat and harmful rays while remaining breathable. Installation requires separate hardware, but once mounted the sail offers consistent shade and a neat finished look.

Key Features

• 190 GSM Virgin HDPE: Thick, non-recycled fabric resists tearing and fading and is proven in lab UV testing to outlast recycled material.
• UV Stabilized Compound: Treated fabric prevents drying out and brittleness so the sail maintains strength over time under sun exposure.
• 95% UV Blockage: Blocks most harmful ultraviolet light and noticeably reduces temperature under the canopy for patios, pools, and carports.
• Breathable Woven Design: Allows air and water to pass through so rain does not pool and the shaded space stays ventilated.
• Reinforced Construction: Double layered stitched seams and stainless steel D-rings at corners improve attachment strength and reduce fraying.
• 3 Year Limited Warranty: Coverage for normal weather and use gives added confidence in material and workmanship.

Who It's For

The ColourTree CTAPRT16 is best for homeowners, small business owners, and installers looking for a heavy duty shade sail that will stand up to prolonged sun exposure, especially in hot climates. Its right triangle shape and custom size make it useful for awkward corners, patios, poolside areas, and carports where a rectangular sail would not fit neatly.

People who need a complete mounting solution should note that hardware kits and cables are sold separately; anyone unwilling to purchase proper stainless hardware or install cable attachments may want a different option that includes a full mounting kit. Those expecting fully waterproof roofing should also look elsewhere since the fabric is breathable and allows water through.
