ColourTree CTAPRT16 11ft x 18ft x 21.1ft Blue Right Triangle Sun Shade

In this review of the ColourTree CTAPRT16 right triangle sun shade sail, the bottom line is straightforward: this is a heavy duty, commercial-grade shade for anyone who needs long-lasting UV protection in a triangular layout. The reviewer found it best for patios, poolsides and carports where high UV exposure and heat reduction are priorities. The single biggest reason to buy is the thick 190 GSM virgin HDPE fabric treated with a UV stabilized compound, which delivers noticeably better resistance to fading and wear compared with typical recycled material.

Key Features

• 190 GSM Virgin HDPE: The thick, non-recycled fabric provides a sturdy feel and resists tearing and deformation during regular use.
• UV Stabilized Compound: Treated material resists drying out and fading, extending expected lifespan under strong sun exposure.
• 95% UV Blockage: The woven fabric blocks most harmful UV rays and reduces temperature under the shade for more comfortable outdoor use.
• Breathable Weave: The permeable structure allows air and rainwater to pass through, preventing water pooling and reducing wind load.
• Reinforced Edges and D-rings: Double layered stitched seams and stainless steel D-rings provide stronger attachment points for secure installation.
• Commercial Warranty: A 3 year limited warranty offers added confidence in durability under normal weather and usage.

Who It's For

This shade sail is ideal for homeowners, small businesses and property managers who need reliable sun protection over a triangular area such as a corner patio, poolside lounging spot or carport. The 11' x 18' x 21.1' right triangle shape fits many retrofit situations where rectangular sails would leave gaps or require complex rigging.

People who want a very lightweight DIY option or expect minimal sun exposure may prefer less substantial fabric, and anyone who needs installation hardware should be prepared to buy a separate mounting kit and appropriate cabling, since ropes and kits are not included.

Pros & Cons
