ColourTree CTSLT Custom Size 9ft x 18ft x 20.1ft White Right Triangle

Our review of the ColourTree CTSLT Custom Size 9' x 18' x 20.1' White Right Triangle Sun Shade finds it best for homeowners and small businesses who need a robust, breathable canopy that blocks sun without trapping heat. The single biggest reason to buy is the thick 190 GSM virgin HDPE fabric treated with a UV stabilized compound, which according to lab testing resists sun degradation far better than recycled alternatives and offers long-lasting protection for patios, pools, and carports.

Key Features

• 190 GSM virgin HDPE: Thick, non-recycled fabric provides a dense weave that improves durability and resists tearing compared with recycled materials.
• UV stabilized compound: Laboratory UV testing shows enhanced resistance to fading and drying, helping the canopy last through prolonged sun exposure.
• 95% UV blockage: The woven fabric significantly reduces harmful UV and lowers temperature in shaded areas for safer outdoor time.
• Breathable design: The mesh allows air and water to pass through so rain does not pool and the shaded area stays ventilated.
• Reinforced edges and hardware: Double layered stitched seams and stainless steel D-rings provide strong attachment points for secure installation.
• Three year warranty: A limited warranty covers normal weather and use, giving buyers added confidence in the product's lifespan.

Who It's For

The ColourTree sun shade is ideal for homeowners with patios, balconies or above-ground pools who want substantial UV protection and a breathable canopy that reduces heat. Small businesses with outdoor seating or carports can also benefit from the heavy duty 190 GSM fabric and reinforced corners for a tidy, long-lasting shade solution.

Customers who need a precise fit should note this is a custom size right triangle and installation hardware is sold separately, so those who prefer an all-in-one kit or who require an exact commercial engineering spec might want to consider a different system that includes mounting hardware or professional installation services.
