17x18 ft Sun Shade Cloth with Grommets - 95% UV Patio Cover

In this review of the 17x18 ft sun shade cloth, the bottom line is simple: it is a practical, heavy-duty patio cover for anyone who needs reliable sun control without blocking airflow. Built from high density polyethylene with double-sewn edges and reinforced copper grommets, this shade stands out for durability and straightforward setup. The single biggest reason to buy is its combination of 95% UV protection and breathable knit construction, which keeps outdoor spaces cooler while still allowing water to pass through.

Key Features

• Durable HDPE fabric: The high density polyethylene knit resists tearing and fraying, extending the life of the shade in regular outdoor use.
• Reinforced edges and grommets: Double-sewn hemming and copper grommets every 2 ft provide secure attachment points for long-term mounting.
• 95% UV protection: Blocks most harmful sun rays while preserving breathability so covered areas stay cooler.
• Water-permeable design: The fabric sheds water drops through the knit, reducing pooling and preventing sag after rain.
• Easy installation: Includes zip ties or ropes so the cover can be fastened without extra tools and with minimal effort.
• Customizable options: Available in multiple sizes and colors to fit different pergolas, patios, and gardens.

Who It's For

This shade cloth is well suited for homeowners and renters who want an affordable, effective way to reduce sun exposure over a pergola, patio, carport, or gazebo. It is also a good pick for gardeners or pet owners who need a breathable cover that provides shade while allowing air and water to pass through.

Those who need a rigid, water-tight canopy or a permanently sealed roof should look elsewhere, since the knit fabric is designed for breathability and water drainage rather than full waterproofing. Also, if you expect to frequently remount the grommets under heavy tension, consider reinforcing attachment points as some users report grommet strain during installation.

• Size options and custom colors make it versatile for many outdoor spaces.

Cons

• Grommets can stress or tear if mounted with excessive force; some reinforcement may be necessary.
• Not fully waterproof due to its breathable knit construction, so it will not keep heavy rain out.

Frequently Asked Questions

Will this shade block most of the sun?
Yes. The fabric is rated to block about 95% of UV, which cuts direct sunlight substantially while allowing airflow.

Is it waterproof?
No. The knit construction allows water to pass through to avoid pooling, so it is not intended as a waterproof canopy.

What hardware is needed to install it?
Zip ties or ropes are included and no special tools are required, though users sometimes add extra reinforcement at grommets for high-tension setups.
