90% 12x20ft Sun Shade Cloth for Outdoor Deck Patio Pergola - 90% UV

Our review of this 12x20ft 90% sun shade cloth finds it best suited for homeowners and gardeners who need heavy sun blocking and straightforward installation. The biggest reason to buy is its combination of a high 90% shade factor and robust 185 GSM HDPE knit, which delivers meaningful sun protection and cooler outdoor spaces without sacrificing airflow. Installation is simple thanks to grommets every 20 in and reinforced taped edges, making it a practical choice for patios, pergolas, chicken coops and carports where coverage and durability matter most.

Key Features

• 90% Sun Protection: Blocks up to 90% of harmful UV rays to reduce heat and protect people and plants beneath the cover.
• 185 GSM HDPE Material: High-density polyethylene knit resists tearing and fraying for longer-lasting outdoor use.
• Brass Grommets & Reinforced Edges: Double-stitched brass grommets and taped edges add strength at attachment points and simplify mounting.
• Versatile Use: Sized and constructed for patios, pergolas, gardens, carports and chicken coops where broad shade and privacy are needed.
• Improved Airflow: The knitted fabric permits airflow to limit heat buildup while still providing strong shade and privacy.
• Easy Installation: Grommets every 20 in on all sides let users hang the cloth securely without excessive fiddling.

Who It's For

This shade cloth is ideal for homeowners who want a large, effective cover for decks, pergolas or patios and for gardeners seeking to shield plants from intense sun while allowing ventilation. It also works well for DIY projects like chicken coop enclosures and carport covers where privacy and UV reduction are priorities.

Those needing a decorative pergola canopy with fine aesthetic detail or an ultra-heavy-duty industrial tarp should consider alternatives, as this product balances durability and breathability rather than being a thick waterproof tarpaulin.

Pros & Cons

Pros

• High 90% shade factor keeps areas noticeably cooler and protects from UV exposure.
• 185 GSM HDPE knit construction feels substantial and resists fraying under normal use.
• Brass grommets and reinforced taped edges ease installation and improve holding strength.
• Grommets every 20 in make attaching the cloth straightforward for most setups.

Cons

• Mixed customer reports on long-term durability at grommet points suggest extra care or additional reinforcement may be needed in high-wind installations.
• Not a waterproof cover, so it does not replace a rainproof tarp for heavy precipitation.
