ColourTree 4 ft x 21 ft Black Custom Shade Cloth - 90% Sunblock

In this review of the ColourTree 4 ft x 21 ft Black Custom Size Shade Cloth the bottom line is simple: this is a practical, no-frills shade solution for pet owners and gardeners who need strong sun protection with airflow. The reviewer found it most useful as a kennel roof or fence privacy screen because the woven HDPE fabric blocks up to 90% of sunlight while remaining permeable so heat does not trap. Installation is straightforward thanks to evenly spaced grommets, and the option for custom sizes made in the US is a meaningful advantage for nonstandard enclosures.

Key Features

• Permeable HDPE fabric: Allows air and water to pass through so covered areas stay cooler and dry out after rain, reducing humidity and heat buildup.
• 90% sunblock: Blocks most sunlight and UV to protect pets and plants while still admitting enough light for visibility and comfort.
• Durable woven mesh: The fabric resists wear and retains structure when fitted as a roof or side panel, providing reliable longevity.
• Grommeted edges: Grommets placed evenly along the edges make attachment with zip ties or cord fast and secure on kennels, fences, and frames.
• Custom sizing available: Special sizes can be ordered to fit odd-shaped runs, small coops, or oversized playpens without awkward trimming.

Who It's For

The ColourTree shade cloth is aimed at dog owners, poultry keepers, and small greenhouse users who need a breathable cover that reduces heat and provides privacy. It works particularly well for kennel roofs, fence privacy, pet playpens and chicken coops where airflow and sun protection matter more than full blackout.

Those who need a waterproof tarp, total blackout fabric, or insulated roofing should look elsewhere; the material is explicitly non-waterproof and not 100% opaque, so it is not intended as a full weatherproof or darkroom solution.

Pros & Cons

Pros

• Blocks up to 90% of sunlight while staying breathable, which helps reduce temperature inside enclosures.
• Durable woven mesh that customers report holding up well as a roof or screen over time.
• Evenly spaced grommets make installation quick and compatible with common fasteners like zip ties.
• Custom sizes available and made in the US, useful for nonstandard applications.

Cons

• Non-waterproof fabric will let rain through, so it is not a substitute for a waterproof tarp or shelter roof.
• Not fully blackout; while adequate for pets, it will not create complete darkness for certain plant or privacy needs.

Our Verdict

The ColourTree 4 ft x 21 ft Black Shade Cloth is a solid value for pet owners and small-structure users who need strong sun protection with airflow. It performs well as a kennel cover, fence screen or coop shade and is durable enough for regular outdoor use, while custom sizing makes it flexible for odd layouts. If waterproofing or total blackout is required, consider a different product, but for breathable heat management this is a sensible, cost-conscious choice.
