ColourTree Custom Size 18ft x 18ft x 25.5ft Brown Right Triangle Sun

In this review of the ColourTree custom size right triangle sun shade sail, the bottom line is simple: this is a durable, heavy duty shade sail for anyone needing reliable UV protection and long-lasting outdoor coverage. It stands out because of its 190 GSM 100% virgin HDPE fabric, which the reviewer found noticeably thicker and less brittle than recycled alternatives after prolonged sun exposure. For patios, pools, carports or balcony corners that need a breathable, high UV block solution, this sail delivers consistent shade and reasonable longevity.

Key Features

• 190 GSM virgin HDPE: Thick, non-recycled fabric provides a sturdier feel and resists tearing compared to thinner recycled sails.
• UV stabilized compound: Laboratory-tested fabric resists drying and fading, extending usable life under constant sun exposure.
• 95% UV blockage: Blocks most harmful UV rays and noticeably reduces heat and glare in shaded areas.
• Breathable woven construction: Allows air and water to pass through so rain does not pool and airflow remains unhindered.
• Reinforced edges and stainless D-rings: Double layered seams and heavy stitching secure corners and help the sail maintain shape under tension.
• Three year limited warranty: Backed by a warranty that covers normal weather wear for added buyer assurance.

Who It's For

The ColourTree right triangle shade sail is best for homeowners and small commercial users who need a robust, long-lasting canopy that withstands intense sun. It suits patios, poolsides, balconies, carports and 90 degree corner installations where a custom-sized triangular sail fits neatly. Those who value fabric strength and UV testing results will appreciate the 190 GSM virgin material and UV stabilization.

It is less suitable for consumers who want an all-in-one mounting kit included, since installation hardware is sold separately, or for people expecting a lightweight, temporary fabric for occasional use only. Also, if exact tensioning hardware and professional mounting are required for large spans, plan to buy compatible high-quality cables and fittings.

Frequently Asked Questions

Is mounting hardware included?
No. Installation hardware kits are sold separately and each D-ring will require a cable or fitting; use non-nylon cables recommended for strength.

How much UV protection does this sail provide?
It blocks approximately 95% of harmful UV and is treated with a UV stabilized compound for long-term sun resistance.

Can the fabric handle rain and wind?
The woven, breathable HDPE allows water and air to pass through to avoid pooling; reinforced edges and D-rings improve wind performance but proper tensioning and quality hardware are important.
