ColourTree 4ft x 21ft Green Custom Size Shade Cloth with Grommets

In this review of the ColourTree 4 ft x 21 ft Green Shade Cloth, the bottom line is simple: this is a practical, heavy-duty shade solution for outdoor pet areas and small structures. The cloth is made of permeable HDPE woven fabric that blocks up to 90% of sunlight and UV while still allowing air and water to pass through, so it reduces heat without trapping moisture. It is especially useful as a dog kennel cover, greenhouse screen, fence privacy panel or chicken coop roof where breathability and privacy matter most.

Key Features

• 90% Sunblock: The woven mesh blocks most sunlight and UV to noticeably reduce heat exposure in shaded areas.
• Permeable HDPE Fabric: Air and water pass through the material, preventing moisture buildup and keeping ventilation for pets and plants.
• Grommeted Edges: Evenly placed grommets make installation with zip ties or rope straightforward and secure.
• Durable Construction: The mesh fabric stands up to outdoor use and provides privacy without easily tearing under normal conditions.
• Custom Sizes Available: Manufacturer offers made-to-order sizes for projects that do not fit standard dimensions.

Who It's For

This shade cloth is aimed at pet owners, small-scale growers and homeowners who need a breathable, durable cover for kennels, pens, greenhouses, fences or coop roofs. It works well where shade, privacy and airflow are priorities rather than full blackout or waterproofing.

Those who need a fully waterproof tarp, total blackout or an opaque fabric should look elsewhere; this product is explicitly non-waterproof and is designed to let air and light through while providing substantial sun protection and privacy.

Pros & Cons

Pros

• Blocks up to 90% of sunlight, helping to lower temperatures under the cover.
• Permits airflow and water drainage thanks to the HDPE woven construction, reducing heat buildup and dampness.
• Grommets make attachment fast and stable for a variety of mounting points and applications.
• Custom sizes available for non-standard enclosures or retrofit projects.

Cons

• Not waterproof, so it will not stop rain from passing through or keep an area dry.
• Not 100% blackout; although effective for animals with poorer vision, it does not create total darkness.
