ColourTree Order to Make Custom Size 21 ft x 24 ft x 31.9 ft Blue

In this review of the ColourTree custom right triangle sun shade sail, the bottom line is simple: it is for homeowners and commercial users who need a large, durable fabric canopy that blocks intense sun and holds up over time. The most compelling reason to buy is the fabric - a 190 GSM 100% virgin HDPE mesh treated with a UV stabilized compound- which the reviewer found delivers robust shade and color retention where lighter recycled sails often fail. Installation is straightforward if you use proper hardware, and the sail performs well over patios, pools and carports.

Key Features

• 190 GSM virgin HDPE: Thick, non-recycled fabric resists tearing and retains strength after extensive UV exposure for longer service life.
• UV stabilized compound: Laboratory-tested material prevents drying, fading and brittleness so the sail stays usable through seasons.
• 95% UV blockage: The woven mesh cuts most harmful UV and noticeably reduces heat in shaded areas during peak sun hours.
• Breathable weave: Air and water pass through the fabric to avoid pooling while still providing effective sun protection.
• Reinforced edges and stainless D-rings: Double layered seams and heavy stitching secure corners and resist fraying under tension.
• Three year warranty: Limited warranty provides added confidence in normal weather and usage conditions.

Who It's For

This shade sail is aimed at people who want a durable, commercial-grade canopy for patios, pool decks, balconies or carports where strong sun and occasional wind are concerns. It suits homeowners, small businesses and property managers who will pair the sail with proper shade sail hardware and anchor points.

It is not ideal for buyers who expect a lightweight seasonal cover or who do not want to invest in separate mounting hardware; the sail requires compatible cables and fittings (nylon ropes are not recommended). Those needing an exact custom triangular fit should measure carefully to match the 21 ft x 24 ft x 31.9 ft dimensions to their mounting points.

Pros & Cons

Pros

• Heavy 190 GSM virgin HDPE feels noticeably more robust than thinner recycled sails.
• Effective 95% UV blockage that lowers heat and protects shaded surfaces.
• Sturdy construction with reinforced seams and stainless steel D-rings for secure anchoring.

Cons

• Requires separate hardware kits and proper cable choices, which adds cost and planning to installation.
• The large, fixed triangular size means exact placement and measurement are essential to avoid fit issues.

Frequently Asked Questions

Will this sail keep the area much cooler?
Yes, the 95% UV blockage and dense woven fabric reduce direct sunlight and lower surface temperatures in shaded areas.

Can I use my own ropes to hang it?
Use steel cable or recommended shade sail hardware rather than nylon rope; the product guidance warns that nylon can break under stress.

Is the sail waterproof?
No, the fabric is breathable to allow water and air through, so it prevents pooling but is not a waterproof tarp.
