ColourTree 17ft x 18ft Green Sun Shade Sail Canopy - Heavy Duty UPF50

In this review of the ColourTree 17' x 18' Green Sun Shade Sail Canopy, the bottom line is simple: it is best for homeowners and small businesses who want heavy duty, breathable sun protection without building a permanent structure. The reviewer found the sail's 190 GSM 100% virgin HDPE material and UV stabilized compound delivered reliable shade and durability, making it a practical choice for patios, pools, balconies and carports. Installation requires separate hardware kits, but once up the canopy reduces heat and blocks most harmful sunlight.

Key Features

• 190 GSM Virgin HDPE: The thick, non-recycled fabric provides increased durability and resists tearing under prolonged sun exposure.
• UV Stabilized Compound: Laboratory-tested material resists fading and drying out, helping the sail last longer in direct sunlight.
• 95% UV Blockage: The woven fabric blocks most harmful UV rays and noticeably lowers the temperature beneath the canopy.
• Breathable Design: The weave allows air and water to pass through so rain does not pool and shaded areas stay ventilated.
• Reinforced Seams and D-rings: Double layered stitched edges and stainless steel D-rings provide sturdy anchor points for long-term outdoor use.
• 3 Year Limited Warranty: Warranty coverage under normal weather and usage gives added confidence in the product's expected lifespan.

Who It's For

This shade sail is ideal for homeowners who need a cost-effective, temporary canopy over a patio, pool area, balcony or carport and value a breathable fabric that prevents water pooling. Small commercial settings such as outdoor seating areas that require a durable rectangular sail will also benefit from the 190 GSM material and reinforced corners.

People who want a fully permanent, custom-framed roof or who prefer a product that includes mounting hardware in the box should look elsewhere, since installation hardware kits are sold separately and proper cables are required for secure attachment.
