Right Triangle Sun Shade Sail 12ft x16ft x20ft - Heavy Duty UV Block

In this review of the ColourTree right triangle sun shade sail, the bottom line is simple: this is a heavy duty, long-lasting canopy for anyone who needs reliable UV protection and strong construction for patios, pools or carports. The reviewer found the sail's 190 GSM virgin HDPE fabric and UV stabilized compound delivered noticeably better durability and shade compared with thinner recycled sails, making it a practical choice for homeowners and light commercial use who want a breathable, 95% UV block that still allows airflow and prevents water pooling.

Key Features

• 190 GSM virgin HDPE: Thick non-recycled material provides a firmer, more tear-resistant surface that holds shape under sun exposure.
• UV stabilized compound: Laboratory tested durability reduces fading and drying so the fabric lasts longer in intense sunlight.
• 95% UV blockage: Effectively reduces heat and harmful sunlight in the shaded area to make patios and pools more comfortable.
• Breathable woven fabric: Allows air and rain to pass through so there is no pooling water and the covered area stays ventilated.
• Reinforced seams and stainless steel D-rings: Double layered stitched edges and heavy stitching at corners improve longevity and make installation points secure.
• 3 year limited warranty: Manufacturer warranty provides added confidence for normal weather and use.

Who It's For

This sun shade sail is well suited to homeowners, small business owners, and renters who want robust, long-lasting shade for a patio, swimming pool area, balcony or carport. It is especially useful in sunny climates where UV exposure and fabric degradation are a concern, and where a breathable fabric that prevents water pooling is preferred.

It is not aimed at buyers who need a complete installation kit included, since hardware is sold separately, or those who prefer a decorative, lightweight fabric over a heavy-duty commercial-grade canopy. Customers without suitable anchor points or who insist on nylon ropes should plan to buy correct steel cables and hardware for best results.
