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

In this review the ColourTree 17' x 18' grey sun shade sail is assessed for homeowners and light commercial users who need durable, breathable UV protection. The bottom line: this shade sail is best for patios, poolsides and carports where long-lasting sun blockage and low maintenance are priorities. Built from a thick 190 GSM virgin HDPE that passed extensive UV testing, the sail delivers solid heat reduction and weather resistance without trapping water, making it the kind of practical canopy a reviewer would recommend for everyday outdoor shading.

Key Features

• 190 GSM Virgin HDPE: Uses non-recycled material tested for prolonged UV exposure to resist drying, tearing and fading for longer life.
• 95% UV Blockage: The woven fabric blocks most harmful UV rays and noticeably reduces temperature in shaded areas for more comfortable outdoor use.
• Breathable Construction: The weave lets air and rain pass through so water does not pool and the shaded area stays ventilated.
• Reinforced Edges and D-rings: All edges are double layered with heavy stitching and stainless steel D-rings for secure mounting and less fraying.
• UV Stabilized Compound: The fabric includes UV stabilizers proven in lab tests to extend lifespan compared to recycled materials.
• Three Year Warranty: The product includes a limited three year warranty under normal use for buyer reassurance.

Who It's For

This sail is aimed at homeowners, small businesses and installers seeking a robust, low-maintenance shade solution for patios, balconies, swimming pools and carports. It suits people who prioritize UV protection and longevity over ultra-light or decorative sails and who can provide solid anchor points like poles, trees or walls.

Those who need a custom measured fit, integrated hardware, or a fabric lighter than 190 GSM should look elsewhere; installation hardware is sold separately and precise mounting attention is required to avoid stress on anchors.
