ColourTree CTAPRT10 21 ft Triangle Shade Sail - Heavy Duty UV Block

In this review the ColourTree 21' x 21' x 21' triangle shade sail is judged as a practical, heavy duty option for anyone needing reliable sun protection for patios, pools or carports. The single biggest reason to buy is the use of 190 GSM 100% virgin HDPE with a UV stabilized compound, which the reviewer found gives stronger resistance to fading and tearing than typical recycled sails while still allowing airflow and preventing water pooling.

Key Features

• 190 GSM virgin HDPE: The thick non-recycled fabric provides a durable, long-lasting canopy that resists common sun damage better than recycled blends.
• UV stabilized compound: The material was laboratory-tested for prolonged UV exposure so it is less likely to dry out, fade or crack over time.
• 95% UV blockage: The tightly woven mesh significantly reduces harmful UV and lowers temperature in shaded areas, making it useful for patios and pools.
• Breathable woven fabric: Air and water pass through the weave to prevent pooling in rain while keeping ventilation under the sail.
• Reinforced edges and stainless D-rings: Heavy double-stitched seams and stainless steel D-rings improve fit and attachment strength for a secure installation.
• 3 year limited warranty: Manufacturer coverage under normal use offers reasonable peace of mind for residential and light commercial settings.

Who It's For

This shade sail is well suited to homeowners and small businesses who need a robust, long-lived shade canopy for a patio, balcony, pool area or carport where UV protection and airflow matter. Installers who prefer commercial-grade components will appreciate the heavy stitching and stainless D-rings.

It is less appropriate for buyers who need a quick temporary tarp or who cannot supply proper shade sail hardware kits; the sail requires separate cables and fittings and nylon rope is not recommended.

Pros & Cons

Pros

• Very durable construction from 190 GSM virgin HDPE that stood up well in sun and wind in real use.
• Blocks up to 95% of UV while remaining breathable to avoid water pooling.
• Reinforced seams and stainless D-rings make installations stable and long lasting.

Cons

• Hardware kits and cables are sold separately, so the buyer must plan additional purchases for proper installation.
• Size accuracy can be important for angled corners; custom sizing or careful measurement may be needed for exact fits.
