ColourTree 8 ft x 21 ft Blue Custom Shade Cloth - 90% Sunblock

In this review of the ColourTree 8 ft x 21 ft Blue Custom Shade Cloth for dog kennels and outdoor enclosures, the bottom line is simple: it is a practical, breathable sun barrier that significantly reduces heat and provides privacy without fully blocking airflow. Designed as a permeable HDPE woven fabric, the shade cloth is best for pet owners who need durable sun protection and ventilation rather than a waterproof or blackout cover. The review focuses on everyday performance, installation ease and how well the fabric manages temperature and privacy for animals.

Key Features

• Permeable HDPE fabric: The woven material allows air and water to pass through, which helps keep kennels and pens cooler while preventing pooling when it rains.
• 90% sunblock: The cloth blocks up to 90% of sunlight and harmful UV, reducing direct sun exposure and lowering interior temperatures for pets and plants.
• Grommeted edges: Grommets are placed evenly along the edges for easy attachment with zip ties or rope, making installation quick and secure.
• Custom size option: The product can be made to order in special sizes, which is useful for irregular kennel roofs or fences that need a tailored fit.
• Durable mesh construction: Customers report the material feels sturdy and holds up as a roof or side screen, offering long-term value for outdoor use.
• Not waterproof: Because the fabric is permeable rather than sealed, it will not act as a waterproof tarp but is intended to balance shade with ventilation.

Who It's For

The ColourTree shade cloth is ideal for dog owners, chicken coop keepers, and greenhouse users who want to reduce heat build-up without creating a sealed, humid environment. It works well as a kennel cover, fence privacy screen, or pet playpen shade where airflow and UV reduction are priorities.

People who need a fully waterproof cover, total blackout for light-sensitive animals, or a completely solid wind barrier should look elsewhere. Likewise, if a rigid, insulated roof is required, this breathable mesh fabric is not a substitute.

Pros & Cons

Pros

• Effective sun and UV reduction that lowers temperature in enclosures while allowing airflow.
• Durable HDPE woven fabric that customers describe as good quality and long lasting.
• Grommets along the edge make it straightforward to install with ties or clips.
• Custom sizing available so irregular areas can be covered without major modification.

Cons

• The material is not waterproof, so it will not keep areas dry during heavy rain.
• It is not 100% blackout; it reduces visibility but does not offer complete light exclusion.
