ColourTree 18 ft x 18 ft Blue Sun Shade Sail Triangle - Heavy Duty

Our review of the ColourTree 18 ft x 18 ft Blue Sun Shade Sail Triangle finds it best suited for homeowners and light-commercial spaces that need a durable, breathable sun cover. The single biggest reason to buy is the fabric: a 190 GSM 100% virgin HDPE weave treated with UV stabilized compound, which the manufacturer says passed extensive UV testing and promises stronger resistance to fading and tearing than recycled alternatives. Installers should plan on buying dedicated hardware and cable separately for a secure, long-lasting fit.

Key Features

• 190 GSM virgin HDPE: Thicker, non-recycled material designed to resist tearing and degradation under prolonged sun exposure.
• UV stabilized compound: Fabric treated to reduce drying out and fading so the sail keeps its structure and color longer in outdoor conditions.
• 95% UV blockage: Woven fabric blocks the majority of harmful UV and cuts sun and heat in shaded areas for patios, pools and carports.
• Breathable weave: Allows air and water to pass through, avoiding water pooling and reducing wind stress on the sail.
• Reinforced edges and stainless D-rings: Double-layer hems and heavy stitching make attachment points stronger and easier to secure.
• 3 year limited warranty: Warranty covers normal weather and usage and custom sizes are available within a 3-7 business day make time.

Who It's For

The ColourTree 18 ft triangle works well for homeowners, small businesses or pool owners who need a large, durable sunshade that breathes and resists UV damage; it is especially useful over patios, above-ground pools and seating areas where heat reduction and sun protection are priorities. DIY installers who are comfortable sourcing proper hardware will appreciate the sturdy D-rings and clear recommendation to use steel cable rather than nylon rope.

This sail is less ideal for someone expecting an all-in-one kit since installation hardware is sold separately, and for buyers who need custom long-term warranty protection beyond three years or who require a guaranteed tensile rating for extreme wind sites; consult a professional or choose purpose-built shade structures for very exposed commercial roofs.

Pros & Cons

Pros

• High-quality 190 GSM virgin HDPE material that aims to outperform recycled fabric in UV longevity.
• Breathable construction prevents water pooling while still blocking up to 95% of harmful UV.
• Reinforced hems and stainless steel D-rings simplify secure mounting when paired with proper cable hardware.
• Available in custom sizes and backed by a 3 year limited warranty for normal use.

Cons

• Installation hardware is not included, and improper rope choices can cause failures, so extra purchases are required.
• Customer reports on durability are mixed; some users have reported tearing under certain conditions, so expectations should be tempered for high-wind exposure.
