ColourTree Custom Size 18ft x 18ft x 18ft Green Triangle Sun Shade

Our review of the ColourTree 18ft x 18ft x 18ft green triangle sun shade sail finds it best suited for homeowners and small commercial spaces who need reliable UV protection and a durable, low-maintenance canopy. The single biggest reason to buy is the heavy 190 GSM 100% virgin HDPE fabric treated with a UV stabilized compound, which delivers long-lasting color and resistance to tearing compared with recycled material. Installation is straightforward with proper hardware and the breathable weave prevents water pooling while blocking 95% of harmful UV rays.

Key Features

• 190 GSM virgin HDPE: Thick, non-recycled fabric provides stronger tension and longer wear under constant sun exposure.
• UV stabilized compound: Laboratory-tested to resist drying, fading, and tearing so the sail maintains appearance and function over time.
• 95% UV blockage: Reduces direct sun and lowers surface temperature in shaded areas for patios, pools, balconies and carports.
• Breathable woven design: Allows air and water to pass through, preventing pooling and reducing wind strain on the fabric.
• Reinforced seams and D-rings: Double layered stitched edges and stainless steel D-rings provide secure mounting points for strong, long-lasting attachment.
• Three year limited warranty: Warranty coverage gives added confidence under normal weather and use.

Who It's For

This shade sail is a practical choice for homeowners, small businesses and property managers who want a robust, commercial-feel canopy that blocks most UV and stands up to strong sunlight. It works well over patios, swimming pools, carports and true 90 corner installations noted by customers.

Those seeking very lightweight or decorative fabric sails, or buyers unwilling to purchase separate hardware kits, should look elsewhere; successful installation requires proper shade sail hardware and cable (do not use nylon ropes) which are sold separately.
