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

In this review the ColourTree 4 ft x 21 ft Red Custom Size Shade Cloth is examined for pet owners who need a simple, durable way to reduce heat and provide privacy in outdoor enclosures. The bottom line: it is a practical kennel and coop cover that blocks up to 90% of sunlight while remaining breathable, so it noticeably lowers temperature and improves comfort without trapping moisture. The fabric is permeable HDPE woven material with reinforced grommets, and the option for custom sizes makes it especially useful for irregular fences and runs.

Key Features

• 90% Sunblock: Blocks the majority of sunlight and UV to reduce heat and sun exposure for dogs and poultry.
• Permeable HDPE Fabric: Allows air and water to pass through so the cover remains ventilated and dries quickly after rain.
• Evenly Placed Grommets: Grommets along the edges make installation fast and secure using zip ties or rope.
• Custom Sizes Available: Can be ordered in non-standard dimensions to fit odd-shaped runs, kennels, or greenhouse frames.
• Durable Mesh Construction: Woven fabric resists tearing and performs well as a roof or fence privacy screen under regular use.
• Non-waterproof Design: Permits drainage and airflow, avoiding pooled water and reducing humidity inside enclosures.

Who It's For

This shade cloth is ideal for pet owners with outdoor kennels, chicken coops, or playpens who need privacy and sun protection without sacrificing ventilation. It is well suited for people who want a long-lasting cover that can be attached quickly with zip ties and who value the ability to order a custom size for an exact fit.

It is less appropriate for buyers who need a fully waterproof tarp or a blackout barrier; the fabric is intentionally permeable, so those wanting total rain protection or complete visual blackout should consider a different product. For most backyard uses, however, it balances shade, airflow, and durability effectively.

Pros & Cons

Pros

• Provides strong sun and UV reduction, keeping enclosures noticeably cooler.
• Breathable woven fabric prevents heat buildup and allows water to drain through.
• Grommets make mounting quick and stable on fences, runs, and frames.
• Custom sizing option helps achieve a neat, secure fit for unusual spaces.

Cons

• Not waterproof, so it will not keep out heavy rain or create a dry shelter in storms.
• Not fully blackout; it reduces visibility but does not create total darkness.
