ColourTree 12' x 18' Beige Sun Shade Sail Rectangle Canopy — 190 GSM HDPE, UPF50 UV Block, Water-Permeable

ColourTree's 12' x 18' beige sun shade sail is a heavy-duty, water-permeable HDPE canopy that blocks up to 95% of UV while remaining breathable and built for long outdoor life.

This rectangle shade sail is made from 190 GSM 100% virgin HDPE with UV-stabilized compound and reinforced edges, designed to reduce temperature and protect outdoor spaces like patios, pools, balconies and carports. Its open-weave fabric allows rainwater and air to pass through so water won’t pool, and each corner includes a stainless steel D-ring for secure attachment. ColourTree offers three years of limited warranty and can customize sizes on request.

How does this shade sail reduce heat and sun exposure?

The tightly woven virgin HDPE fabric is engineered to block up to 95% of harmful UV rays while still permitting airflow. That combination lowers surface temperature beneath the sail without trapping hot air.

• 95% UV blockage rated for sun protection
• 190 GSM virgin HDPE for consistent weave density
• Breathable mesh design prevents heat buildup
• Reduces glare and direct sunlight for shaded comfort

What makes the material more durable than other shade sails?

ColourTree uses 100% virgin (non-recycled) HDPE that passed extended UV testing and a UV-stabilized compound to resist fading and drying. The thicker 190 GSM construction and heavy double-stitched hems protect against fraying and deformation from regular outdoor exposure.

• 20000-hour lab UV testing for proven longevity
• 70% more durable versus recycled HDPE under sun exposure
• Double-layer reinforced seams for edge strength
• Extra heavy stitching around stainless D-rings

How do I install this 12' x 18' rectangle shade sail?

Installation requires separate mounting hardware and cable ropes; each corner’s stainless D-ring connects to a cable or hardware kit anchored to a fixed point. Do not use nylon rope—ColourTree recommends metal cables or their hardware kits for best performance.

• Each corner has a stainless steel D-ring for secure fixing
• Use steel cable or purpose-made shade sail hardware (sold separately)
• Anchor to posts, trees, walls or poles spaced for a rectangle layout
• Regularly inspect hardware for tension and wear

Will the fabric collect rain or require frequent maintenance?

The woven HDPE is water-permeable so rain passes through instead of pooling; this lowers strain on attachment points and reduces cleaning needs. Occasional rinsing is usually sufficient to remove dust or pollen.

• Breathable weave prevents water pooling after rain
• Low-maintenance: hose down to clean
• Resistant to fading and mildew with proper airflow
• Designed for outdoor year-round use; remove only in extreme storms if desired

Who is this for? This ColourTree 12' x 18' beige sun shade sail suits homeowners, renters, and small-business owners who need a durable, high-UV-protection canopy for patios, pool decks, carports or outdoor dining areas. It’s ideal for anyone wanting long-lasting sun protection with low maintenance—especially users who prefer heavier, laboratory-tested virgin HDPE fabric and secure stainless-steel attachment points.
