ColourTree 17ft x 20ft Red Sun Shade Sail Canopy - Heavy Duty UV Block

In this review of the 17' x 20' ColourTree red sun shade sail canopy, the bottom line is simple: it is for homeowners and small businesses who need a heavy duty, UV-blocking cover that keeps patios, pools and carports noticeably cooler. The reviewer found the sail's standout feature is its 190 GSM 100% virgin HDPE construction treated with a UV stabilized compound, which delivers strong sun protection and a tactile feeling of thickness compared with lighter recycled sails. Installation requires proper hardware, but once tensioned the canopy provides dependable shade and reduced heat under bright sun.

Key Features

• 190 GSM virgin HDPE: The thick, non-recycled fabric resists tearing and feels more substantial than typical recycled sails.
• UV stabilized compound: Laboratory UV testing informs a fabric treatment that reduces fading and drying, extending usable life in sun-exposed applications.
• 95% UV blockage: Blocks most harmful UV rays to lower temperature and sun exposure on patios, pools and balconies.
• Breathable woven fabric: Allows air and water to pass through to prevent pooling and to keep the shaded area ventilated.
• Reinforced seams and stainless D-rings: Double-layer stitched edges and heavy stitching at corners improve load distribution when mounted.
• Three year limited warranty: Coverage for normal weather and use provides added purchasing confidence.

Who It's For

This sun shade sail is aimed at homeowners, renters with mounting options, and small commercial spaces that need reliable UV protection for patios, pool areas, balconies and carports. Buyers who prioritize sun blocking, a thicker non-recycled fabric and low-maintenance breathable material will find it well suited to outdoor shading needs.

It is not ideal for customers who need included mounting hardware or who expect a solution for severe wind conditions without additional structural reinforcement; installation hardware and quality cables are sold separately and are required for a secure, long-lasting mount.
