ColourTree 4 ft x 21 ft Grey Shade Cloth with Grommets - 90% Sunblock

In this review of the ColourTree 4 ft x 21 ft Grey Shade Cloth, the bottom line is simple: it is a practical, heavy-duty shade solution for pet enclosures and outdoor barriers where sun reduction, airflow and privacy matter most. The reviewer found the cloth effective at blocking up to 90% of sunlight while remaining breathable, making it ideal as a kennel roof or fence privacy screen. The fabric is permeable HDPE woven material with evenly spaced grommets, and the product is offered in custom sizes and made in the US.

Key Features

• 90% sunblock: The fabric blocks most sunlight and UV, helping to reduce heat and light inside kennels and covered areas.
• Permeable HDPE fabric: Air and water pass through the mesh so ventilation is preserved while still providing significant shade.
• Grommets for easy install: Grommets placed along the edges make it straightforward to secure the cloth with zip ties or rope to frames and fences.
• Custom sizes available: If the standard 4 ft x 21 ft does not fit, custom sizing can be ordered to match a kennel, greenhouse or playpen.
• Durable construction: Customers report the weave and finish hold up in outdoor conditions and perform well as a roof or divider.

Who It's For

This shade cloth is best for dog owners, small animal keepers and gardeners who need a breathable cover that reduces heat and provides privacy without trapping humidity. It works well as a kennel cover, fence privacy screen, greenhouse shade or chicken coop shade where airflow is important.

Those who need a fully waterproof tarp or a total blackout screen should look elsewhere, since the fabric is intentionally permeable and not designed to be 100% light blocking or water-resistant. Buyers requiring rigid UV-proof panels or insulated roofing will also want different materials.

Pros & Cons

Pros

• Blocks up to 90% of sunlight, lowering temperatures in covered areas.
• Breathable HDPE weave preserves airflow and reduces heat buildup.
• Evenly spaced grommets make installation quick and secure with zip ties.
• Custom sizes and US manufacturing make it adaptable to nonstandard openings.

Cons

• Not waterproof, so it will not keep rain out of an enclosure.
• Not a total blackout product, so it reduces but does not eliminate visible light.
