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

In this review of the ColourTree 4 ft x 21 ft Brown Shade Cloth a reviewer looks at who benefits most and why it stands out. The bottom line: this is a practical, heavy-duty shade tarp for pet owners, small greenhouse users and anyone needing a breathable privacy screen. It excels at reducing heat and providing privacy without trapping moisture thanks to its permeable HDPE woven fabric, and the evenly spaced grommets make installation straightforward for fence, kennel or coop applications.

Key Features

• Breathable HDPE fabric: The permeable woven mesh allows air and water to pass through so the covered area stays cooler and avoids puddling after rain.
• High sunblock: Blocks up to 90% of sunlight and UV to significantly reduce temperature and sun exposure for animals or plants beneath.
• Grommeted edges: Grommets placed evenly along the edges make it easy to secure the cloth with zip ties or rope and keep it taut.
• Durable construction: The mesh fabric is designed for outdoor use and customers report it holds up well as a roof or privacy screen in daily use.
• Custom sizing available: Special sizes can be ordered so you can get a fitted cover for an odd-sized kennel, coop or greenhouse frame.

Who It's For

This shade cloth is best for dog owners who need a kennel cover that reduces heat and offers privacy while still allowing airflow, small-scale greenhouse users wanting partial sun control, and backyard chicken keepers looking for a breathable coop cover. The fabric's 90% sunblock and permeability make it well suited to locations where shade and ventilation matter more than full blackout.

It is less appropriate for buyers who need a waterproof tarp or full blackout fabric; this product is explicitly non-waterproof and not 100% opaque. Also, if you need heavy-duty canvas for industrial sheltering, a different material would be preferable.

Pros & Cons

Pros

• Effective heat reduction and privacy while remaining breathable, praised by users for airflow and temperature control.
• Evenly spaced grommets make installation fast and compatible with zip ties for fences and frames.
• Durable HDPE woven fabric that customers describe as good quality and functional for roof-like use.

Cons

• Non-waterproof design means it will not keep rain out and is not a substitute for a waterproof tarp.
• Not 100% blackout, so it will not fully block light for applications that require complete darkness.

Specifications

Our Verdict

Frequently Asked Questions

Is this shade cloth waterproof?
No. The fabric is permeable HDPE designed to allow water and air through, so it is not waterproof.

Will it keep my dog calm by blocking view?
It is not 100% blackout but it provides strong privacy and blocks up to 90% of light, which is generally sufficient since dogs have limited vision.

Can I use the grommets to attach it to a fence?
Yes, grommets are evenly placed along the edges and work well with zip ties or rope for fence and kennel installation.
