18x36 ft Shade Cloth 80-90% Sunblock - Cool, Breathable Garden Cover

Our review of the 18x36 ft Shade Cloth finds it best for gardeners, pet owners and patio users who need a large, breathable sun barrier without heavy structure. The cloth's main selling point is its balance of high sunblock and airflow: rated around 80-90% block, the fabric reduces heat while still allowing air and water to pass through, which helps plants and animals stay cooler and avoids moisture buildup. It is lightweight and easy to hang for temporary or semi-permanent shade solutions.

Key Features

• Sunshade and Breathable: Blocks a large portion of sunlight while permitting airflow so shaded areas stay cooler without trapping humidity.
• High Density Material: Made from high density polyethylene, the cloth is light but provides strength and stretch for common outdoor covers.
• Reinforced Edges: Lock-stitch knitting and reinforced corners reduce unraveling and help the cloth resist tearing at attachment points.
• Grommeted for Easy Hanging: Grommets are placed along reinforced edges every 120 in so the sheet can be secured in multiple configurations.
• Multiple Uses: Suited for greenhouses, patios, kennels, chicken coops, pools and other areas where sun protection and airflow are needed.
• Easy to Clean: Breathable fabric allows water to pass and can be rinsed clean with a garden hose.

Who It's For

The shade cloth is ideal for hobby gardeners, small-scale livestock owners and homeowners who need a large, economical cover for patios, pergolas or plant beds. Its light weight and grommet spacing make it suitable for temporary or seasonal installations where airflow and sun reduction are priorities.

Those who need a heavy-duty permanent roof or expect years of abrasion and extreme weather may want a reinforced industrial shade or a purpose-built structure instead, since some customers report mixed impressions of material quality and longevity.
