ColourTree 17 ft x 18 ft Brown Sun Shade Sail Canopy - Heavy Duty UV

In this review of the ColourTree 17' x 18' brown sun shade sail, the bottom line is simple: it is for homeowners and light commercial users who want a durable, breathable canopy that blocks most UV and reduces heat without building a permanent structure. The reviewer found the standout reason to buy is its thick 190 GSM 100% virgin HDPE fabric treated with UV stabilized compound, which gives real confidence that the sail will resist fading and tearing better than recycled alternatives.

Key Features

• 190 GSM virgin HDPE: The thicker, non-recycled fabric offers stronger resistance to sun degradation and prolonged outdoor exposure compared to recycled materials.
• 95% UV blockage: The woven fabric blocks most harmful UV rays, noticeably reducing direct sunlight and surface temperature beneath the canopy.
• Breathable design: The weave allows water and air to pass through so rain does not pool and shaded areas stay ventilated.
• Reinforced edges and hardware: Double layered stitched seams and stainless steel D-rings improve attachment strength and help prevent fraying at stress points.
• Proven UV testing: Lab testing up to 20,000 hours supports the claim of extended life under sun exposure versus recycled HDPE.
• 3 year limited warranty: Coverage under normal weather and use offers extra reassurance for buyers.

Who It's For

This sun shade sail is best suited to homeowners with patios, pools, balconies or carports who want an affordable, semi-permanent shade solution that is easier than building a roof. It also works well for cafes, schools, or small commercial outdoor areas needing a UV-blocking canopy that breathes.

People who need a fully waterproof roof or a custom tensioned architectural membrane should look elsewhere; this product is designed as a breathable HDPE shade sail, not a watertight awning or rigid structure. Also, installation requires proper hardware and attachment points, so those unable to supply secure posts or fixings may prefer professional installation services.

Pros & Cons

Pros

• High quality 190 GSM virgin HDPE gives durability and resistance to fading in sun-exposed settings.
• Blocks approximately 95% of UV, improving comfort and protecting surfaces below.
• Breathable weave prevents water pooling and allows airflow for cooler shaded space.
• Reinforced seams and stainless steel D-rings make mounting secure when used with proper hardware.

Cons

• Not waterproof - breathable fabric allows water through, so it does not function as a rainproof roof.
• Installation hardware sold separately, so buyers must purchase recommended kits and cables to ensure longevity.

Specifications

Our Verdict

For anyone wanting a sturdy, breathable shade that blocks most UV without the cost of permanent construction, this 17' x 18' ColourTree sail is a strong value. The heavier 190 GSM virgin fabric and reinforced construction make it a practical choice for patios, pools and carports, provided buyers use proper hardware and accept that the fabric is not fully waterproof.

Frequently Asked Questions

Will this shade sail stop rain?
Not fully; the woven HDPE is breathable so water passes through rather than pooling, making it unsuitable as a waterproof roof.

What hardware do I need to install it?
Each D-ring needs a cable or wire rope and appropriate anchors; do not use nylon ropes, and a proper shade sail hardware kit is recommended.

How long will the fabric last in sun?
The virgin HDPE was UV tested extensively and is designed to resist fading and tearing significantly longer than recycled alternatives, with a 3 year limited warranty under normal use.
