ColourTree Custom Size 21ft x 24ft Green Sun Shade Sail Canopy - Heavy

Our review of the ColourTree 21' x 24' green sun shade sail finds it best for homeowners and small businesses who need a durable, high-UV-blocking canopy for patios, pools or carports. The single biggest reason to buy is its 190 GSM 100% virgin HDPE fabric, which is lab-tested for long-term UV stability and offers substantial heat reduction while remaining breathable. Installation requires separate hardware kits, but once mounted the sail provides steady protection, resists fading and can survive typical outdoor wear.

Key Features

• 190 GSM virgin HDPE: Thick, non-recycled material proven in lab testing to resist UV degradation and extend fabric life compared to recycled alternatives.
• UV stabilized compound: Treated fabric reduces drying, tearing and fading so the sail keeps its strength and appearance longer under sun exposure.
• 95% UV blockage: Dense woven construction cuts most harmful UV rays and lowers temperature in shaded areas, making outdoor spaces more comfortable.
• Breathable woven fabric: Allows air and water to pass through so there is no pooling after rain and ventilation reduces heat buildup beneath the sail.
• Reinforced seams and D-rings: Double layered stitched edges and stainless steel D-rings give secure attachment points and help prevent fraying and deformation.
• Three year limited warranty: Coverage for normal weather and usage provides added confidence in product longevity.

Who It's For

The ColourTree 21' x 24' shade sail suits homeowners with medium to large outdoor areas - patios, pools, balconies or carports - who want a long-lasting canopy that blocks the sun and reduces heat. It also fits small commercial settings where a reliable UV barrier is needed without obstructing airflow.

Those who should look elsewhere include buyers wanting an all-in-one kit with included mounting hardware or people requiring precise custom installation measurements beyond standard sizes; this product requires separately purchased hardware and proper planning for attachment points.
